8x301.5 2412mhz A64 3000+
Komusa PC4200 Adata chips cas 3 4 4 8 @ 2.9v

no its not stable. i'm riding at 295 though and its solid so far.

4571mb/s not bad for single channel cas 3 eh? ;)

i'm getting another stick to run 2x256 in my AI7 i ordered thursday which has 3.2v capability.

who needs bh5? :p my mushkin bh5 quit at 236mhz cas 2.5 but this stuff is good for 285 cas 3 at least.

[flapperhead]

now thats what i call crankin...

Little OT, but is your PCI bus really running at 33MHz?

[Richard]

That has to be a record for the socket 754 motherboards. :)

You have the Shuttle AN50R, right?

no its running at 50mhz :eek:

and my soundblaster audigy is still working fine :confused:

i don't think its a record. i'm sure there have been people on xtremesystems doing 330 or more.

301 is pretty good for no mods at all though :)

[flapperhead]

If anyones considering pc4000/4400 these sticks (256) are only 70 bux a piece. that is a great deal for pc4800 stable or not! i got ram coming outta my ears, but i think im gonna get some anyway..

[flapperhead]

hey max, when u get that ai7 let me know what kind of speeds ur getting in dc. thnx flapper

[Maxvla]

sure. np.

for now here's a better pic:

these results are repeatable, but not stable. it was not just a fluke thing.

[Albuquerque]

Definately wanting to see how this performs in dual channel... :D

[flapperhead]

amazing....

ask and ye shall recieve.

ordered my 2nd stick of this today should arrive in 3-4 days. my p4 2.6c and abit AI7 should arrive wednesday.

[flapperhead]

hmmm.if the 2nd one runs anything like the first (which i hope),i dont think you're gonna be able to adequately test the rams' limits with the 2.6. at 266. the 2.6 is gonna be running around 3450.. i think you're gonna need a 2.4c

[bill gates]

Whoa! I'm going to order them right now! I wonder what they will do on a Asus p4p800 deluxe with a volt mod @ 3.2v??? I really need some memory that will do 300fsb 1:1. Good thing I still have 2 days to return this Kingston HyperX pc-4000. The adata is cheaper and faster (I hope).

[Maxvla]

just like a billionaire... cheap to the last penny :p ;)

of course i hope every stick runs like max's superstick but its important to be realistic, 295-300 at 2.9v is amazing... plus i dont think higher voltages has too much effect on the newer chips,cause unlike the older d43,the newer d43 chips ive been testing actually dont like more that 2.9v...

[b|ind]

where are you ordering from?

[flapperhead]

komusa, they have memory built to order for them. It seems that the pc4200 hyperram they sell with the adata chips is of very hi quality, cause some of the guys are getting crazy overcloks, and for very cheap!69.00 for 256-238.00 for a gig. i bought some hyperram(adata) pc4000 last sept and it runs like 290 1-1. i think im gonna email them and ask what kind of chips are in the pc3200-3500. here is the link...http://www.komusa.com/

[wannaoc]

Don't forget to mention you have to get the ADATA chip upgrade. Its free but you still have to choose it.

[flapperhead]

oh yeah, get the adata cause i dont know how well the other stuff runs. i just emailed them about their pc3200/3500 hyperram, asking what chips are on them..

Well it may not do 301mhz but it will probably still do better than my kingston. Maybe I won't need the extra voltage, I will try it at 2.85v first. Hopefully I can get some good stuff, it seems like most people are having pretty good results with the adata stuff.

dont get me wrong, i would love it if u got 310 out of em. 1 of my sticks runs to 290 at 2.8 and look at max's crazy oc, so they gotta be doing something right...

[crimedog]

maxvla, why don't you give them more volts and try tighter timings?

[flapperhead]

soon as he gets his ai7, im sure he's gonna hit it with 3.2. im praying its an older adata binned chip. they love 3+ volts...

[Blunt]

i had 2 x 256 and 1 x 512 adata pc4000 it has adata chips and pcb and they ran 275 fsb 1:1 no problem at 2.8v if i had a vdimm mod they would have flew

[flapperhead]

thats why i think the adata stuff runs like a bat out of hell cause they havent been speed binned to death. no pc/4200/4400. u get pc4000 chips and they seem to just get started at 250.

[Maxvla]

my shuttle an50r maxes at 2.9v and no way i'm vmoding the board and killing my a64 chip.

my AI7 with 3.2v should be plenty to get these to shine. :)

i get the AI7 tomorrow and the 2nd stick should arrive by friday.

[flapperhead]

Just an got answer from randy lo at komusa. he says the adata pc4200 is selling well.. no doubt. since his pc3200/3500 comes from the factory with heatspreaders he said its either first grade samsung or whats left of the winbond stock... says it oc's pretty well.. since its pretty inexpensive i may buy a stick and see how it runs

[GWAR]

Here's my result running the same adata pc4200 on a K8N-PRO. @ 2.9 volts.btw is your pcb red on your mem Maxvla..?

http://home.comcast.net/~xgwar/292_fsb.jpg

[flapperhead]

GOOD GOD! another over 290. They must have the best binned batch of chips out of adata.

yes it is a red pcb on mine. good job on 292fsb however your pic won't load. only knew by the filename :p

[Albuquerque]

Come back in here Max, I wanna hear how these puppies are doing in dual channel mode on your AI7 :)

[Maxvla]

don't have the 2nd stick yet :(

supposed to be delivered today. usps delivery confirmation has let me down like 5 times in the past week. never had problems before. :(

on a different note.. i just bought a prescott 2.8e :D should be here in a few days.

[flapperhead]

darn it..

no worries. this same thing happened with my other stick of komusa ram. will probably have it tomorrow.

[tekOC]

What do I have to do to get this Komusa RAM with the Adata chips? Do I have to specifically ask someone or just buy it?

[Maxvla]

its a free upgrade. when you select the quantity on the page its right next to it with the other options.

[tekOC]

What store?

Nevermind, www.komusa.com - thanks again.

The upgrade is not free its an extra 16 bucks for PC4000 and extra 18 bucks for PC4200 :D

huh??

i just went there and pc4200 with adata is 69.00 for 1 256mb stick, the same price as regular pc4200.

[tekOC]

Oh my bad I'm talkin a bout the 2x512 sets.

[Maxvla]

Originally posted by tekOC

still free :confused:

the 16 i see is for copper heatspreaders which you do not need. actually my ram wasn't supposed to come with it but it has one.

[Albuquerque]

Not that I'm going to admit to anything, but I happen to know ;) ;) ;) that the ADATA upgrade on the PC4200 1gb setup was free too ;)

[Maxvla]

oh really? ;) :cool:

[flapperhead]

make sure u are in the hyperram store and not regular store

[Maxvla]

:D got the 2nd stick today :)

this one again has heatspreaders even though i didn't select it and pay more for it.

results later tonight. gotta go to work :(

[Maxvla]

quick run on my a64 the new stick does about 288 mhz max through sandra mem bandwidth test. remember this is with 2.9. i'll have to swap a chip into my AI7 to give it a thorough thrashing. :)

[flapperhead]

still, thats real nice for a $70 stick of pc4200-a 22mhz oc

[Albuquerque]

Yup, I wouldn't complain about 288 for as cheap as it is. If I can get 284 out of it at 1:1, it's exactly what I'm looking for! :cool:

[gplracer]

Do all of the 4200 memory modules on this page have Adata chips on them?

[flapperhead]

are u talkin about this thread?

[Maxvla]

Originally posted by gplracer

no when you select your quantity on the komusa page you must select adata brand chips in a drop down menu. don't worry about heatspreaders cause apparently they put them on whether you pay for them or dont.

[Albuquerque]

Yeah, now I'm curious if mine are going to come with the heatspreaders too. Max, did you order yours via the available free USPS priority shipping, or did you do the UPS? (it sounds like you did UPS, but maybe I'm dumb and forgot?)

Anyway, I'm assuming mine should be here on Tuesday or Wednesday as they actually shipped out on Friday afternoon. USPS Priority usually only takes like three business days, but it will be moving for most of the weekend so here's hoping ;)

[flapperhead]

i think the later batches of this stuff is coming from the factory with the heatspreader on it. cause when i asked eandy lo at komusa about the chips on the pc3200-3500 hyperram he said they were samsung grade A and winbond chips, but he couldnt say definitively in what proportion because their memory builder ships the memory with em already on. what the heck.. a nice copper heatspreader for free also..

[flapperhead]

WAAAAAA me cant wait much longer. MAX.....

[Maxvla]

sorry. i am going to wait til i have my new hd and prescott in that rig before i test out dual channel capabilities.

to run that one rig i'd have to disable 2 rigs and i can't afford to lose the folding power right in the middle of a race.

[flapperhead]

np. ill find something else to obsess about ..(lol)

[Albuquerque]

Well if it makes you feel better, I should have mine here pretty quick. I can give you the results from my rig when they come in; I know that Macci had pretty good luck with my exact motherboard when he did 270 or something FSB at 2-5-2-2 on some Kingston HyperX 2700 (BH5 sticks).

After researching a bit on USPS Priority mail, there's a good chance I can have it as early as this coming Monday. :)

[Maxvla]

i should have both my processor and hd monday or tuesday as well :)

i plan on getting a 240-250mhz fsb oc then ramming 3.2v down this ram's throat and going 4:5 with it :D

[Albuquerque]

Funny enough, this board has those same memory options... THe usual 3:2, 5:4 and 1:1 stuff, but then also 4:5 and 2:3 :D If only I knew what Macci did to vdimm mod this damn thing like he did...

[Maxvla]

most p4 mobos have 4:5. on most 800fsb boards you have to move the bus selection to 667 or 533 for it to appear as an option.

[gplracer]

Flapperhead, I see it now. There is an option when buying for adata chips. BTW I have an aMD motherboard. Do any of you have experience running these chips in an AMD nforce2 board?

[wannaoc]

If its a Barton or XP gplracer then the timings will be a little loose. They will work fine and you will be able to get a nice high fsb most likely but some with tighter timings would work best.

[flapperhead]

i just sold a set of 2x256 hynix bt-d43 date 3/53 to Red02TA. i havent heard from him but ill ask him.. seems max aint having much probs with his hyperram.. ive done alot of testing with this stuff. the newer chips bt/d43 actually perform best between 2.75-2.9,. kinda like the bh6/5 chips. the bh5 runs faster at lower voltages and the bh6 loves the juice. i hope that max got some older chips cause if he did they will resond to the higher voltages

[Albuquerque]

My board doesn't have a strap setting; it gives all memory options all the time. Wierd :confused: Nevertheless, I've found the electrical diagram for both voltage regulators on this board (one specifically for the CPU, another one for the vdimm/vagp/etc) which means maybe I can even get this board to chuck out some more chipset voltage and CPU voltage (limited in BIOS to 1.6v)

[flapperhead]

i just finished checking out my 2nd ic7 i bought from icarius. im gonna do the works(hipro5's 5 mods he did to get the board to run 400 mhz) i emailed hipro5 and asked what mods can be done to the memory itself.(can u imagine getting an extra 15/20 mhz from this memory?) now i have to find a real gem 2.4c so i can use the extra horsepower. i was kinda hoping the 2.8 precott i would be the one but sadly intel didnt do a good job with this cpu

[Albuquerque]

Since I;m running my current 2.4c at stock voltage up this high, I'm assuming it's the ram or the chipset holding me back -- it does even worse in 3:2 mode so that's out of the question.

I would wager that if I can run the FSB up to 292 with memory at 1:1, that would be a very solid system. Even my current 284 is still enough, but I'll always take more if I can get it :p

[flapperhead]

my hyperram wouldnt run didly till i went in and changed the timings to manual . then suddenly 1-1 worked fine

[Maxvla]

took the heatspreader off my slower stick. its a single sided dimm. uses 4ns adata chips on a adata red pcb. the record for this ram appears to be 314mhz using 3.6v. 3 4 4 8. i guess my 301 with only 2.9 is pretty good :)

i'm going to take the spreader off my good one and see if it does any better.

[Albuquerque]

After removing the spreader, did it help with the speed at all? I'm rather uneducated on memory heat-spreader effectiveness, but I've heard a few people saying it works better in some cases.

Just curious if you're seeing any improvement.

[flapperhead]

mine are like welded on. how'd u get yours off max?

[Albuquerque]

It's probably just uber-glue or something; either a ton of heat or a ton of cold would probably allow the spreaders to be snapped off... (guessing)

[Methodx]

I couldn't take it anymore! I had to order some. I just ordered 2 x 256 sticks so I can run in 1:1. Man this is going to be so sweet!

[Maxvla]

you have to remove the chromed clips then it pulls off rather easily. its got some adhesive on the inside but its not like its a death grip. the pad is rather THICK and i don't see how in the world it could help at all in thermal dissipation. this thing must be a good 1/8 of an inch thick.

haven't gotten to my good stick yet. no time this morning. i'll do it tonight :)

[flapperhead]

thats the first thing i tried to do last sept when i got it. the adhesive looks like a thick double sided carpet tape. it wouldnt budge..

[Maxvla]

popped right off for me :confused:

[flapperhead]

Hmmmm, i think when i get home tonite ill try it again. btw i think im gonna try to find a 4/5 ratio on my board and see just how far my best stick will run.. i think it may be available in the 667 selection...

[flapperhead]

finally got the heatspreaders off. my buddy charlie took a couple pics for me..http://www.theforumisdown.com/uploadfiles/1203/gdfer1.jpg

[Maxvla]

yours is green? or is it black?

mine are red. i'll take pics later. i didn't get a cool adata sticker though :(

[flapperhead]

you have to remember these sticks are almost 6 months old. some of the first adata to be sold in us. youre stuff may be speed binned vitesta which is adata brand pc4000 now.http://www.theforumisdown.com/uploadfiles/1203/flap333.jpg


the pcb is green, with adata in the middle in gold letters. sorry for the poor resolution i need to get a camera bad..

[Maxvla]

yeah mine is the same except red.

[Maxvla]

[tekOC]

I will be picking up a set of 512MB kit (256MBX2) PC-4200 533MHz Dual Channel DDR Hyperam with the ADATA chips tommorow.

Only $149.00 :drool: it will be going in my Intel system, so I can push this sweet 2.4C to 3.6GHz.

I dont think my Corsair XMS 512MB Single-Stick DDR that I have right now is gonna cut it, running 260FSB 5:4 right now, fully stable 3.12GHz - havent tried higher and I bet my highest with this RAM will be 270FSB, and this single stick crap is killing my performance, cant wait till dual stick!!!!

[flapperhead]

nice looking ram.. Id be very interested in how fast a gig of this memory would run...

[tekOC]

Yeah only downside is my mobos highest vDDR is 2.85V which sucks balls!!!! Gonna have to perform a volt mod later on :(

[Maxvla]

i was able to do 301.5 again but this time with 3 4 4 7 timings. negligable gain in sandra. 4586mb/s

[Xception]

If you guys had it to do over again would you still opt for the heatspreaders? I just ordered 256x2 for a comp I am building for my bro and didn't ask for them. Wondering if they may come with them anyway. That red pcb is cool looking Max :D

[OCLegend]

That's some MAD numbers Max. I'm new to the forum and OC. I'm gonna do lots of researching about OC and start messing around with it in summer. Too lazy now to look up some stuff, but is the P4S8X any good for OC? I'm running P4 2.4 533FSB.

neither time i ordered did i ask for heatspreaders so they will likely come anyways.

they didn't improve performance. rather limited me to 3 4 4 8 timings compared to 3 4 4 7 at same speed with the spreaders removed.

i would definately recommend the Abit AI7. with the high vdimm option you can really put any ram through its paces.

[flapperhead]

ive never been able to test the max on my fastest stick cause my 2.4c dies at 292. has anyone tried using the 667 strap with the 4/5 ratio in the ic7 bios? if my theory is correct i can run the fsb at 240's and with the 4/5 ratio it will allow me to oc the memory to the 300's...

well that didnt work, when i set the strap to 533 or 400 for 4/5 or 3/4 the mb wont boot WAAAAA drat!

I might just have to try these out and keep them if they will do 288 1:1. I got some other memory around here that I can put in my bro's comp. ;)

[flapperhead]

it is VERY VERY difficult to find ram that will run these speeds at any price...not to mention as cheap as it is.. if u think about it at ddr 600 thats 3.3ns. jeesh my golden sample ti4200's ram wont run this fast. it just blows me away,

[Albuquerque]

YAY! They came!! :DNo heatspreaders on mine, go figure... Red PCB, Adata logo in the center, 4ns Adata chips onboard. Looks exactly like what Maxvla posted after he removed his heatspreaders.

First thing: Flapperhead, don't feel bad. Anything over 200fsb and my board refuses to boot just like yours. If I leave it at exactly 200fsb, it's fine :confused: This sounds like a BIOS issue to me, at least on my board. Maybe for both of us...

Second thing: I simply don't have enough motherboard to run these things as hard as I can. I was topping out at 283 on stock voltage with my previous ram; I'm topping out at 284 on stock voltage on my new ram. To get it stable, I had to completely max out my AGP voltage (which I've now found is tied to my chipset voltage). Otherwise it just stops posting or else freezes in Memtest86. :(

Third thing: I didn't realize f'ing sandra was this huge, so I'll have to wait a bit until I can post benches...

[flapperhead]

wow at stock voltage! yep not too often does memory run an 865/875 mb and a 2.4c into the ground @ 1-1. i just wish i could get the 4/5 divider working, id love to see how far that one stick of mine will run. well guy what do u think was it worth 140.00?(i think i know the answer... lol)

[Albuquerque]

I slightly miscommunicated that last post:

283 was my max FSB when running stock CPU voltage on the old ram
284 is my max FSB now while still running stock CPU voltage.

The problem? No amount of higher CPU voltage gets me anywhere -- it's a limitation of the damned board :( My old ram was running 5:4 at 2.85v, my new Adata ram is running 1:1 at 2.75v. It's sorely obvious this ram has much more capacity, I just can't use it!

Thats a shame. i gotta tell u, if u think u have a plenty more in the cpu and memory, if were u i dont think i could resist an asus or ic7 that would take me all the way. my prob is i havent been able to get a 2.4c that will run past 290 fsb.. waaaaaa....

[Albuquerque]

My Sandra and Aida benchmarks don't look that great compared to many others; I think it's just this board. I really REALLY must resist the urge to upgrade! Arrrggg!!

Quit making me think about it!! :cry: :-/ ;)

[man_utd]

To answer about the p4s8x, not on this ram, that maxes out at 166mhz fsb on cpu, which will get you about 255ish FSB. Thats not even 4200 speeds.

[flapperhead]

yeah, if your getting 284 at stock cpu voltage, sounds like u may have a real sweet overclocking cpu... if u ever want to sell that cpu let me know...

[Albuquerque]

At 166FSB on an i845 chipset, that's 417mhz memory speed at the 2.66x setting (I think that's like 3:4?)

[Maxvla]

yeah those sandra numbers aren't that great. last night i slapped my 2x256 in my IS7 (only 2.8v) and got to 255 before the chip started kicking me. numbers at 255 were about 5700mb/s.

[Albuquerque]

I know, it sucks :( I know it's this board, it gave me crappy numbers on the Kingston ram too. I cannot enable PAT/PAM/PEM/whatever they call it to save my life, even at stock FSB. It had all the features I wanted, but obviously not the performance.

Maybe it IS time to buy another board... Argg... The woman would kill me... :-/

[flapperhead]

you can get a good ic7 refurb from newegg for about 75 bux..
my bw at 290 was like 6600-6700

I'm checking out the IC7-G, but I really want to find one that has the PATA raid on it because I DO NOT want to go through purchasing drives all over again. You guys have me looking at the IC7-G and the P4C800 now; thanks a LOT :p j/k

[crimedog]

anyone been giving these things over 3v? I'm really tempted to see how high my DFI will go.

[Albuquerque]

I'm actually now running these at 2.65v at 284 1:1 on 3-7-3-3... Damn man, I'm seriously considering a new board...

[Xception]

Alb,
I know exactly how you feel about your board maxing out. This AI7 I have runs 288 fsb prime stable, memtest stable and 3dmark stable but will not run 290 without giving me winblowze errors. You know the kind; applications not loading and thinking theyre are new programs installed when theyr'e are not. At fsb 292 all it does is beep at me no matter what the voltage. (mosfets? evil gremlins?)
I have seen guys getting over 300fsb with the AI7 but I know they won't all do it. I am starting to think boards are kinda like chips. You either get a good one or you don't. ;)

any 2.4c that runs that fast on default has a good chance of 3.6 or more, if i could only find one... be advised that those 2 mb's dont go over 2.8v without a mod..

[Albuquerque]

I keep screwing up and typing 3-7-3-3, when I actually mean 3-7-4-4 (if you look at the CPU-Z shot, you can see). But anyway, these chips were still MemTesting away this morning at 284 1:1 on 2.65v, so it's likely that they are stable there. I'll reserve final judgement until I see them later today, but I think they're good :)

If/when my Kingston HyperX sells, I guess I can use that money to pick up a new board. Time for some serious research!

[flapperhead]

congrats... u have 2 rare components.. a great cpu and memory that will run 284 at 2.65v. the third- a mb capable of running 300 is the easiest of the 3 to find, once u get it dont forget to post ur results...

[Albuquerque]

I think I'm gonna keep this board afterall; I just can't find anything that meets what I want. This board is doing pretty good, I just wish my Sandra scores would get higher. I'm also doing some reserach into voltmodding this puppy, which might increase my chances at 300fsb.

Really though, there are quite a few boards out there that have a hard time hitting 300FSB. I've found multiple IS7's, IC7-G's and P4P800's that my current board is out-gunning in terms of stable clockspeed. It just needs some more help :)

I also think the memory timing issues *might* be resolvable by way of changing the chipset registers from something like WPcrEdit from H-Oda. Those slow memory issues are coming from my total inability to manipulate PAT settings; it's either FULL-on or FULL-off and it isn't allowed to be changed over 200fsb. I know of several other MB's that had this issue which were fixed with either hacked BIOSes or upgrades from the company.

Since I'm not quite sure Albatron is that interested in overclocking, I doubt they'll put out such a BIOS willingly :)

[flapperhead]

2 days ago i would have been doubtful. but not after last nite.to make a long long story short, i have 3 different types of ram. somepretested(260 mhz) pc3200 bt-d43, my pc4000 hyperram,(290+) and some winbond bh6 modules. I always assumed my 2.4c ran around 290 cause thats where it usually ran to at 1-1 or 5/4 with my hyperram. well i did some in depth testing with all three types. the bt-d43 modules top speed is 260. so i put the ratio to 5/4 and the cpu only runs to 284. for the heck of it i tried 5/4 with my hyperram with different timings than usual and the cpu runs to 295! wait it gets better!, i put the winbond in and ran 3/2 and the darn cpu booted into the bios at at 305!god only knows how high my cpu is capable of running if i can figure out the correct combination .You are absolutely correct about bios timings and register settings and how they react to memory and fsb. With the correct timings and register setting u may be able to get a much higher overclock, cause i was able to increase my overclock by 21 when theroetically all three memory types were capable of taking my fsb/cpu to the same speed.. flapperconfused...

[Albuquerque]

Yeah, that is rather interesting... I haven't even tried 5/4 yet, duh!! :bang head I got busy last night with a soldering iron and modded my PSU; my 5v line has taken a nosedive since I got this ram. (4.75 normal, sees 4.68 dips on occasion! :eek: )

I haven't reinstalled the modded PSU yet, but my voltages are already a good ~0.75 higher when unloaded. I've also figured out where the voltage points are for doing the VDD and VCC mods to my board, so that's happening tonight or tomorrow.

I figure here in the very near future either I will get as high as this CPU can go, or I'll burn out my motherboard :)

[flapperhead]

when i hit 305 my eyes bulged out of my head, cause the cpu never ran anywhere near that. now im going back to square 1 and retest at every ratio and combination..

Well I'm new to here and to the forum? So Hello All!!

My question is what should I buy? I've read through the thread. Am quite excited! But am quite confused? There are 4000 (4ns) and 4200 (?ns) sticks, red and green, some 6 months old green yet bought in the last week, some new red pcb from a different line of Adata memory, Copper heatspreader or not, Speed Binning to take into account. Lot of factors. Advice! Advice!

Have a new ABIT NF7-S V2.0, Mobile Athlon XP 2500+ new, ready and waiting!!

Sorry 'bout the mess of a message. New to this message editing system.

Thanks All

BTW flapperhead you mentioned:

if u think about it at ddr 600 thats 3.3ns. jeesh my golden sample ti4200's ram wont run this fast. it just blows me away

where did you get "3.3ns" from?

[OneBitOff]

Oh Ya' forgot to mention I'm interestd in buy a 1 gig? Should I buy a matched set of 2 512 or 2 single 512?

Thanks again! :p

[Albuquerque]

Well, something else to ponder: We're buying these sticks because we're hitting FSB's in excess of 280+. We are also running these at very loose timings...

AMD's, especially the NF2 chipsets, really don't seem to be hitting more than about 230 stabily. The newest AMD-based DFI Lanparty motherboards are getting higher, but I'm not sure if they're donig 280 yet.

Why do I mention this?

If your FSB's are never going to see anything above 230-240, this memory will probably perform worse than something that's rated for lower speed and tighter timings. AMD systems prefer tighter timings anyway...

What I would suggest for you is a set of really good PC3500 memory that can run as close to 2-2-2 timings as you can get. It would probably be the same cost as this stuff, but would perform worlds better in a lower-FSB system.

[OneBitOff]

You have a point on the latency of lower fsb memory but I have a dual purpose. I want to use new memory for my new "Cheap" nforce2 system now. In the future though I want to use it in a new intel grantsdale chipset MB in 'bout half a year or so. I figure this ram would fly then with the kind of bandwith we'll be talking 'bout with those MBs. I would get good use out of the memory for a low price at a great performance ultimately. A good compromise on 1 gig of memory. Hedging against the future and still giving the present its due share of performance

What ya' think guy! ;)

[Albuquerque]

Heh, well who am I to complain? ;) It's your system, and I know this stuff would work in it. And if/when you get the bigger and badder system that can run 290+ FSB's, I guess this would indeed make you ready for it!

Of course, at that time, you may have other options available versus this stuff. It all ultimately is your decision, but I"m not exactly sure I'd buy computer parts today for a rig that I'd build when Moore's law has another half-cycle to catch up with me ;)

Know what I mean? :p

[OneBitOff]

Understand but it's still +- 600 ddr that even then could be
expensive and not as good performance. It's a bet! My only question as in earlier was what is everybodies consensious on what to order if I were to order. Heatspreader or not, speed 4000 or 4200. Red or Green PCB. The effect of speed binning on the decision to buy now or l8r when new chip stock comes down the line?

All input would be greatly appreciated!

WELCOME TO THE FORUMS...


this stuff is probably way too fast for what u need, but what the heck, a gig is only 238.00.. the reason why my sticks are green and everyone else's is red is because i bought my hyperram when it first came out in early sept. at that time the fastest they sold was pc4000. since then they have been speed binning (testing )the adata ram and the best overclocking modules have been upgraded to pc4200. that is why so many of the guys are getting these great speeds. its almost like having someone pretest your pc4000 and selling you the best of the best for 5.00 more. as for the ddr 600 and 3.3ns, i got it by taking the actual speed of the ddr600 which is 300mhz and dividing it into 1 billion, which is 3.3ns (a ns- nanosecond is 1 billionth of a second.) anyway welcome to the forums and i invite u to come over to the dark side (intel) so u can really crank your hyperram up...

I got good news! i just booted into bios at 310!!!(i think i have more) not yet stable in windows at 300 yet. im hoping its a memory / ratio/ timing issue, and not the cpu, cause its my dream to run this rig over 300. right now im using 1.74vcore, do i dare bump it up just to see if it responds???

[OneBitOff]

Thank your input was much appreciated and understood!

If you read the rest of my messages today you would see where I am coming from. The pickings in memory are thin and price / performance ratio are low and I'm just trying to get find a bargain in the ruff!

Thanks and keep em' comin'.

[Albuquerque]

No heatspreaders are needed, and you want to get the PC4200 stuff with the "Adata upgrade" selected. That'll get you set up perfectly :)

I got my board to boot at 292fsb after reinstalling the modded PSU; my voltages are significantly better now. Unfortunately it's not stable at 292 or else I'd show some benchmarks :( I upped the CPU voltage just to make sure, but I think it's the northbridge that's causing me this grief. That, or maybe I'm running into the limit on the ram at the 2.85v max voltage I can feed it? That's effectively 584DCDDR, maybe this board needs a VDD mod to get it higher?

Dunno, board mods have to wait till the weekend :)

[Maxvla]

you mentioned you were buying memory now and eventually using it with a grantsdale chipset. the grantsdale chipset will be DDRII not DDRI so your ram will not work in the new board. just thought you should know.

[flapperhead]

The new 915 (grantsdale) will be allowing the use of both ddr 1 and ddr 2. As ddr2 will be too costly for the mainstream until 2005. So intel and other other MB mags are providing slots for ddr1. After all the advantage of ddr2 isn't until the it speed passes 667 and beyond. No advantage over ddr1 now. It's a matter of the economic to performance ratio of the ddr 1 vs. dd2. Have to very slowly ramp up all the technologies so the market won't be shell shocked and get scared off.

[flapperhead]

Well guys i give up(no matter what i do)- i can boot into the bios at 310-312/boot into windows at 301 but it aint totally stable till 288. here i thought i had something going last nite but no luck. weird my pc4000 hyperram actually outruns my cpu .DRAT! WAAAAAAA... anybody else with good news??

[Maxvla]

well the guy i bought my prescott from is taking his merry time shipping it so who knows when i'll be able to run this ram properly...

[flapperhead]

i have a 2.8 prescott sitting here, been too disgusted to test it based on reports from the other guys, they just run too hot and beat the h*ll out of the mb. I had a line on a 2.4c that runs 3.6+ over at extreme forums last nite till "hardass" their hatchet mod deleted me for not having enuff posts... Have u ever seen a 2yr old throw a super tantrum and flip himself all over the floor ?? LOL.. well back to the drawing board...

Albuquerque,

Mine isn't stable at 292 either but I did get a screenie. Seems stable at 285 tho at least in memtest. This ADATA pc4200 is awesome!! And for the price can't be beat. Might have to go for another gig :D

I'm not going to directly embed this huge image -- it's 1152x864 (my full desktop) (http://www.hyundaiproject.com/computer/screen.JPG). This is my ADATA doing 255fsb 1:1 at 2.5-7-4-4 with the PAT-alike enabled!. Bios 1.03b for me seems to allow the PAT setting up to right at 255, and then it fails miserably again.

Kinda wondering if I shouldn't buy a 2.8 M0 so I can "only" top out at 255 :p FSB

thats pc4560/ not bad for 238.00 eh? the corsair and ocz pc4400/ is going for about 400.00. Can u imagine the shock i had when last sept when i tested one of my sticks to 290 at 2.78v?I cant vouch for their other speeds because i havent tested any, but these pc4200 adata modules are without a doubt consistantly the fastest and by far the most inexpensive ram for someone who wants hi fsb- memory 1-1...

[Albuquerque]

I have an odd scenario now... With this 1.03b bios, I'm suddenly getting literally billions of errors in Memtest86 2.8 (maybe I should try a newer one?) Prime and Windows both are just as stable as before, but I'm getting huge numbers of errors in every test -- no matter if it's single channel or dual channel, and from every speed from 266mhz 3:2 all the way to 575mhz 1:1. :confused:

Since Prime isn't kicking me out, I'm working on the assumption that MemTest86 is just having some conflict with this BIOS. I'm going to reload my 1.02b version and Memtest again just to make sure...

[flapperhead]

yeah sounds like bios timing..

[Albuquerque]

Sure enough, 1.03f fixed the problem - go figure :confused:

Here's something more interesting: I think I am maxing out the ram. I know for a fact that 284fsb is stable because it's memtested on the 1.02b bios for 24hrs. With the latest bioses (1.03b and 1.03f) I can post higher than 284...

Memtest ran fine through two loops at 284, so I booted it at 288 (576DDR) and immediately got errors! It wasn't tons of errors like the previous deal, just a few here and there. Knowing how this board undervolts the CPU when loaded, it's not impossible that the ram is being undervolted at load too.

I think it's time for the vmem mod before I can get any higher...

[flapperhead]

are u running them at 2.8v? i wonder how well they will respond to higher volts..

[Albuquerque]

Yeah, I need to update my sig don't I? ;) 2.85v is where they're at now. The 2.65 isn't stable in this BIOS; go figure :p

[fadaway0000]

I have some questions for you since we have the same board.

I can run stable at a 245 fsb with only .01 volts to the CPU and .03 to the ram with this new ram (komusa 1 gig 4200) But if I try at all just to overclock ddr I crash and have to reset the Bios. Any setting it does this. Now I'm sure I can get my CPU up to 250 or more easily but first need to get some cooling issues in line.

I guess my question for you is have you tried just overclocking the memory ( really just running it in 2.50 turbosettings )and not the CPU. What Am I missing/ Why won't it let me overclock just the ram?(or just run this memory at it's own stock setting of 533 without having to overclock the CPU?). I have done this with cheap 2100 ram and overclocked it with no problems.:bang head

[Albuquerque]

It's the strap setting in the northbridge... In english, most northbridges seem to have problems when an 800FSB chip is installed and then a memory divider higher than 1:1 is selected. Several different people that I've spoken to on this forum among others seem to have the same problem.

It works fine on my same board if I'm using a 400 or 533 FSB processor.

[lbbo2002]

Thanks for everyone posting pics. I have seached the New Zealand shops for some of Adata that matchs what you getting in the US and I came up with this. Is this what everyone is getting?

[flapperhead]

they appear to be an earlier version of the adata pc4000 like mine(green). my sticks are dated 331 like yours and also 329. the newer sticks have a red pcb. but nevertheless my pc4000 runs REAL well..

[Maxvla]

looks good. mine are 0402's even though i ordered them a week apart they came as same manufacture date.

[mattspalace]

Ugh! Mine won't be here until Monday, but I'll be puttin the stress on this stuff when it does come!

[Xception]

Mine are only 256 sticks :( but.. they are 0404's and are running 288 1:1 @ 2.7 volts :D (shows up in eq as 2.78) I just passed prime x2 tt for 24 hours @3.0 volts with them then I figured they should be burned in. So I kept lowering them and checking memtest. They have made 10 passes of test 5 so far without any errors. I will test them more later and let you know. I did notice that when I got them down to 2.9 I had to up my vcore to eliminate errors in memtest. This ram is awesome :D

[Albuquerque]

I'm starting to wonder if I need more vcore now, just like Exception mentioned. My memory seems to generate errors around 288-289FSB even at max voltage, but after turning up the CPU voltage to 1.6v the errors went down significantly (however still kept coming)

1.6v is my uppermost option for CPU voltage, so I'll have to voltmod the board to get any more. Fortunately that's pretty easy to do for the CPU, as there's a post online about the ADP3180 controller my board uses over on XS.com. However my board is a slightly different version than the one posted over there, because it uses an RT9174 regulator for memory instead of the "normal" RT9203. The difference is, the RT9174 is a three-channel regulator versus the single channel RT9203, so I need to find out which channel is running my RAM (and a voltmeter isn't seeming to help me :( )

But hey, one of those channels is likely my northbridge and the other two are likely VDD and VDDQ. Should be a good deal when I figure it out :)

Arg! Damn this memory for making me go so fast! :D

[Methodx]

I also got the red ones without heat spreaders just like Maxvla. I think they've stopped sending you free heatspreaders. They probably read these boards and realized ppl were figuring out that they would get heat spreaders without having to pay extra for them, lol.

[flapperhead]

i took mine off, the less clothes the better, for memory and women..

[Maxvla]

this is getting ridiculous. guy says he got the prescott back due to incorrect address, now i have to wait til friday...

bah!

[lbbo2002]

The Adata I just got (not from Komusa) is on read PCB. Looks the same as what has been reported for others. No one carried the 4200 so I have the PC4000 model. 2 X 256meg sticks.

Have to test it tonight and report back.

[flapperhead]

im pretty sure komusa is binning their adata pc4000 modules cause adata doesnt officially sell pc4200, so the primo, fastest sticks go to their pc4200. thats gotta be the reason why almost every stick runs so darn fast, cause we arent talkin about 5-10 mhz headroom, were talkin 20-30+ mhz which is amazing in my book..

[bill gates]

Wow you guys are awesome! I forgot about this thread and then I stumbled acrosss it again today. I can't believe that this many people are getting these high of speeds with this ram. I agree with flapperhead, this must be the best memory you can get for the money. I am willing to bet it probably outruns anything corsair or ocz has for $400. I didn't have the money to get any yet (saving for 1gb). However I did just sell a piece of junk celeron 800 computer for $200 today so maybe it is finally time to get some. I just got a 2nd I865 motherboard to test it on so now I have an Asus P4P800 deluxe and an Abit IS7. My cpu booted up at 300fsb in the IS7 but wasn't stable due to this crap-tastic Kingston pc-4000 memory even with a 3:2 setting. Well I know I can afford 512mb but I really want the 1gb. Has anyone seen how high these things will go with more than 2.9v yet??? I think my cpu is easily good for 300fsb+ I just hope this memory might be able to go that high too with a volt mod. That is my dream...300mhz fsb 1:1 with 1 gig running in dual channel. Drool.......:D

[tekOC]

I got my 2x512mb PC-4200 Adata set today, did the vdimm mod to my mobo and popped the sticks in for dual channel mode.

I score around 4500mb/s in Sandra with my 2.4c @ 285fsb(x12).
and I'm not saying thats good, I'm saying thats horrible seeing how Alburqurque is scoring over 6000mb/s at 284fsb and a Albatron mobo, same ram, same stepping CPU.

something is very wrong with your rig. 4500mb/s is LOWER than stock 200mhz on a 800fsb chip which is 5000mb/s. you are either running in single channel mode or there's a problem with your mobo.

[Maxvla]

wow this thing is HOT :D

its not a good oc'r, but i have another one coming tomorrow.

this one seems to be 'everyday' stable about 3250mhz 70c load.

i guess this board doesn't like running 4:5 either cause it wont boot at all no matter what its set to.

[mattspalace]

Hopefully mine will do a lil better for ya - or was this is one the CPU you got from me?

[Albuquerque]

To the guy that was running 4500mb/sec -- yeah, something is terribly wrong with your system. My ~6000 is actually horribly low compared to what it should be, but that's because I cannot run PAT any higher than 255fsb without stability issues.

In fact, with this board running at 255fsb and PAT enabled, I score ~5800, a mere two hundred points shy of almost 70mhz more speed. It's amazing the difference that PAT can make :)

I'm hoping a voltmod will cure my issues with PAT over 255fsb...

very nice!!

unfortunately for me i don't think i'm ever going to run a low enough multiplier p4 to get this high fsb. i thought i could run 4:5 using the 533 strap, but it appears it won't work. dumb intel needed to include a divider that ran ram faster than cpu with 800fsb chips. :(

i'm looking at a 3.0c. hopefully i'll get lucky and get a wu stepping.

yep same prob with me my cpu doesnt run well over 290. 1 of my sticks runs that fast at 2.78v. so i put in the 533/strap changed to a4/5 ratio and... nothing. it wont boot .DRAT! If i could only find a real fast 2.4c.. oh well...

exception, thats amazing and at 2.7v no less. the god of fast memory has definitely blessed this adata/hyperram

[gustav]

5:4 doesnt usually work well with pc4000 or higher from what ive heard/read, dont know what it is...

so from these few screen shots, i see people running 290 fsb and 290 on the ram (1:1), yet the scores dont get past 7,000 MB/s. this is odd that my pc3500 (running 220mhz) with 2-2-2-5 timings and 5:4 divider gets about 6,000 MB/s...i would think it would be less....i know my chip can do 3.6ghz stable, ive done it with the 3:2 ratio (ram was at 200mhz, pc3200 speeds). so what im trying to figure out based on people results with this mem is will i get better performance with my chip at 3.6ghz, 1:1 with komusa, 3-4-4-8 timings, or will it run better at 3.6ghz, 5:4 with mushkin pc3500, volt modded board to give it 3.2 volts, 2-2-2-5 timings? from my current setup, i think keeping my current ram would be best after a vold mod to my board. i would think the scores would be better with the komusa ram because its in 1:1 with the bus speed, so something is screwy i guess?!?

actually im trying to run my ram at a ratio of 5 to my fsb of 4. to do that u have to put in the 533 strap. but i havent found anyone who has been able to do it with an 800 fsb chip.

to be honest i doubt there would be much difference between running 300 1-1 3-4-4-8 and 300 5/4 @2-2-2-5.For me there's just the mystique of running 300 1-1. That definitely qualifies for bragging rights. . plus who would have thought some smaller outfit would put out such consistantly fast ram at such bargain basement prices!!!. Thats why maxvla has so many hits on this thread..

What the hell is wrong with this damn thing I'm not even stable at 280fsb, random BIOS corruption computer shutting off.

I dont know anymore, I'm giving it 3-4-4 timings and with a vdimm mod.

I dont have a clue, what chips mushkin uses. since there are only a couple companies that make chips capable of 250+ and hynix by far is the most common, id have to say they are some form of hynix chips.. I also believe adata uses binned hynix chips, with blanks on top carrying their name. secondly i remember when adata first came out last summer with their pc4000, alot of the reviews found theses chips were way ahead of their time in terms of overclocking headroom.. It seems they were probably doing some sort of speed binning on their pc4000. well in my opinion komusa has taken it 1 step further. they are speed binning the the adata pc4000 (which already has known tested chips) and only using the fastest in their pc4200.. Now this is only my opinion but, it is the only logical explaination of why these darn stiks seem to be so consistantly fast and inexpensive..

[bill gates]

Well I finally got my 512mb stick installed. I tried it in the Asus P4P800 deluxe and the Abit IS7 they both maxed out at 300mhz fsb with this memory! I did a volt mod to the asus and put 3.2v to the memory and did not get any higher. So adding extra voltage doesn't make any difference on this ram. I am going to order another one now and see how it does in dual channel mode. I do have PAT enabled and I am using the most loose timings I can 3.0-4-4-8. Still I am so happy with this memory. For $119 how can you choose anything else? Next I am going to put the memory in 5:4 and see just how high I can push this little 2.4c!!!!!!!


P.S. @300fsb bios temps are still reading 24 degrees celcius. Of course I know it's not 100% correct but I ran it for a while and then turned off the power and removed the heatsink and put my finger on the center of the chip and it wasn't even warm!

Yes sir! 300 1:1 I haven't tested stability yet because I don't have enough time until late tonight. I will keep you posted on my results. But if it boots into windows without problems at 300 then my guess is it will probably be stable up to at least 290. I will also try some tighter timings tonight too.

I bought the pc-4200 ADATA stuff.

Update: The 300mhz fsb is not stable. I tried to run sisoft sandra burn in test and it locked up after the 4th time around. I will see what happens with PAT turned off. I think 290 is going to be more realistic for stability. Not that I'm complaining though...:D

[flapperhead]

LOL ! first rumours,then disbelief, then disrespect(jealousy?) ,lastly grudging envy...

[bill gates]

O.k. here are the final results: 288mhz 1:1 is the highest it is 100% stable at. I have "PAT" enabled and the memory set to turbo. Also the best timings it will do are 3.0-4-4-5 and this is all with 2.85v on an Asus P4P800 deluxe. This is SINGLE-CHANNEL because I only have 1 stick right now so I don't know how good it will perform once I have dual channel enabled. I ran memtest-86 to test the stability and let it run for about 1 1/2 hours with no errors at the above mentione settings. Also my P4 wouldn't go any higher than 300mhz even with the meory set to 3:2 and with upping the voltage to 1.65v, it just doesn't like anything higher than 300mhz fsb. I am too afraid to add any more voltage than that, especially when it does 300mhz with stock voltage.

I have to say that I am very, very pleased with this memory. I searched for many months to find good memory and in my opinion this is the best stuff out there and it comes at a great price too!!! If anyone has a 2.4 or 2.6c then you will want this stuff!!! Thanks to everyone here for helping me find this stuff and for sharing your overclocking experiences, it has been a lot of fun. Keep posting your results. What has been the highest overclock with these things running in dual channel? Sorry I don't have any pics because I don't have a way to host them.

[Maxvla]

just bought 2x256 bh5 for 50 bucks, does that qualify? ;)

[lbbo2002]

Well had a chance to play with the Adata (red PCB) this weekend.

First this ram HATES :mad: both my IS-7's. Post dies at 258 on one and 265 on the other. No joy (hard hang on post). Just FYI on that.

On the MB- AI7 I can post and run all the benches at 290 but only prime stable for ~3-4 hours. This is with the 300FSB 2.4C CPU out of the IS7

100% prime stable at 284 but I need 3.05v to get therr :)

Adata PC4000 Memory running at 1:1

[lbbo2002]

First pic is mem at 284.

This is BH-6 running 2,2,2,5 at 292. I am confused why its low compared to the 1:1 at 284. Both have GAT at a,a,a,d,d

Any idea?

[Maxvla]

your bh6 is not doing 292mhz 1:1 that explains the 'lower' score than you thought you'd have.

[lbbo2002]

Yea the Bh-6 is at 5:4 but at tight timings? I know the AI7 benches like 300 points less off the Sanda mem vs IC7/IS7 but I didn't think 1:1 would match tight 5:4 timings.

Time to play with all the different benchs and see what the results are at 5:4 vs 1:1. Maybe I will lower the 5:4 down to enable GAT that would provide a differentiator don’t you think?

Any who for $217 NZ (~$149 USD) I got great 2x256meg RAM that does a great job of running high FSB at 1:1. Currently the adata has found a home in my IS-7 doing 250 with my 3.0c, 1:1 and it likes it :)

Help, please..... :(

[mattspalace]

My 2 x 512MB PC4200 (Adata) showed up today.. I'll run it through its paces over the next couple of days and provide some results.

[flapperhead]

cool hope it runs well

[mattspalace]

Okay, just ran a quick test..

Currently doing 260FSB 1:1 ratio with 2.9v to the memory and 1.65v to the CPU.. God this 2.8C I have is a real badass.. that's just under 3.7GHz on AIR folks..

I have an SL6Z3 2.4C sittin in a box. That will probably be going in soon, so I can push higher without worrying about maxing out the CPU.

[mattspalace]

Okay, this is getting interesting now...

Currently at 265fsb with 1:1 ratio. 3-4-4-8 timings (of course). 2.9v to the memory and 1.65v to the CPU. -And yeah, 3.7GHz!!
Of course I still need to check for stablility as I'm using Abit's OC-Guru right now.

My Sandra bandwidth score is only 5910. That seems a little low doesn't it?

[mattspalace]

LOL.. Nope 3.7GHz isn't stable. :rolleyes:

[flapperhead]

wow really nice cpu... i got about 6600-6700 and that was at 290 1-1- so i guess ur in the ballpark. there may be some game acceration settings that will give u a little more..

[Sophisticated]

yes...compliments on your cpu..gotta lucky egg....i should be getting some pc4200 adata's soon...

[mattspalace]

While this 2.8C I have does seem to be a really nice chip, to find out just how good this memory is will require a swap for my 2.4C.
I'll be back with some new results later. This RAM easily does DDR500 though, which is a nice change..

[lbbo2002]

mattspalace

I would be surprised if you didn't get 560-580 DDR our those sticks. I haven't been as lucky as some to get 1:1 at 290+ dual channel but its a rock at 284. Get a random error 1 in every 25 test runs with memtest from 285-290 at 1:1 so I call it good at 284 since it passed all the 24hr prime,3d, etc tests.

Waiting to hear about the 2.4c. I got mine up to 298 on the Adata on the AI7 at 5:4 only good to 290 at 1:1 (post, run bench marks, not prime stable over 8hrs).

flapperhead was your mem scores on the IC7? This AI7 is 300+ or so lower than my IS7 clock for clock in Sandra bench marks. Didn't notice much in anything else.

[flapperhead]

yeah, it was my ic7. seems of course, the 2x256 run faster, which is logical. but gosh 284 (pc4550)is a heck of an oc for a gig of ram..

[lbbo2002]

flapperhead

What are you Ram settings and game acc? Can you run at cas 2.5 above 260? Can you run 2.5,3,3,7 below 250? Seems the best I can do is 2.5,4,3,7 upto 265 then its 3,4,4,8 up to 290.

[flapperhead]

you know those are some good questions, i can run around 220-224 @2-3-3-5. but i havent tested speeds with 2.5-4-4-7 .my game acc i put to auto. my 2.5 timings are probably the same as yours, but when i get a chance ill test them..

[aldamon]

So, I'm gathering that this RAM would suck on the Athlon 64? I think the A64 would choke on 3-4-4-8. Too bad, I'm considering a Shuttle AN50R and my Buffalo CH5 isn't up to the task, unless I drop to 6:5.

[Albuquerque]

Alda,

Maxvla's very first post when he started this thread was on an AMD64 rig. All things considered, it was kicking a lot of butt Sandra-wise even despite it's very lax timings. Go have a look :)

[aldamon]

Sandra scores are pretty. Real-world apps and a comparison to a lower FSB with tighter timings would be prettier. Loose timings are one thing, but 3-4-4-8? I find it hard to believe those settings could beat a substantially lower FSB with tight timings on the A64.

[flapperhead]

maxvla's 301 is a whole lot of bw, yes even at 3-4-4-8. is it the fastest for every app and game,?probably not. bh5/bh6 is great ram, but its expensive and rare now. and to get to 240- 250 u need plenty of volts.. max is running this stuff at 2.9, and u just cant beat the price..

[mattspalace]

I know some of you have been looking for some results from me and my 1GB kit of Adata PC4200... So here's where I'm sitting right now..I swapped out my 2.8C for my 2.4C (My 2.8C is still a sweet CPU).

CPU 2.4C SL6Z3 - unbelievably enough, I got this off Newegg refurbs. Thank you to whomever sent this back so I could get a 1GHz overclock!

Currently using 1.6v to the CPU, 2.9v to the memory, 3-4-4-8 timings and the following:

CPU/RAM Ratio = 1:1
FSB for both = 285MHz
Operating frequency of 3.42GHz (Stable and room for more)
GAT/PAT = A-A-A-D-D
Sandra mem bandwidth = 6350MB/s

Needless to say I'm VERY impressed with this memory. :D

My guess is this is going to do just as well as a 2 x 256 kit, as I'm nearly there now. I'm just making sure everything is stable.

Will post more later! Woooo!!! this is FUN!

[lbbo2002]

mattspalace , great OC at 1:1...GO FOR 300!!! That would be so good to have a 1:1 300FSB rocket :D

Keep us posted. Looks like 290 has been done so its time for more.

When you hit your max could you bencth SuperPi, PCMark04, and 3dmark01 - before and after would be good but who has all that data just lying aroung :)

Thanks

[flapperhead]

wow, congrats u got 1 fast set of modules. do u think the memory will go even higher?

[mattspalace]

Well it passed memtest-86 at 285fsb with no errors so I'm sure there is room for more.. I think this memory doesn't particularly like high voltage though. It seems most happy at 2.9v.

Yeah when I find the highest I can go stable, I'll run some benchies and post screenies.

[lbbo2002]

Any thing over v3 and the Adata I have got very unstable. This is why I think all those none volt modded boards should do fine with this stuff.

I've been keeping quiet on the benchmark front because I'm getting another Alby board as a warranty replacement. Mine had a serious problem suddenly with a CPU mosfet burning up :eek:

Fortunately I hadn't touched it yet with a soldering iron; I was about this close (holds fingers about 1/8 inch apart) from doing it this coming weekend now that I have all the needed parts and equipment.

I have also tested the CPU and the ram in another machine and neither seem to have suffered. The other machine was a POS and only had FSB options to like 255, of which both my CPU and ram booted right up and ran at stock voltages at 1:1 so they're not damaged :D

I should have the new board tomorrow, so I'll report back if per-chance it performs better than my previous unit. Here's hoping :D

[lbbo2002]

What??? how in the world you do that??? Your PS is modded right?

Only had than happen on a lightning strike, yikes :cry:, on a UPS ever since :D , you get a power surge?

[Albuquerque]

Actually I'm wondering about my PSU upgrade -- I checked the voltages with a brand new Fluke meter that I borrowed from my boss. The 3.3v line was precisely 3.52, my 5v line was 5.28 and my 12v line was 12.89... Obviously they are higher than stock, but they're well within the 10% tolerance that is usually communicated.

I haven't tested the PSU on another system yet, maybe it took a hit? We had a few storms here over the weekend, but all my equipment is plugged into a good surge protector and my gaming rig (the one that burned) wasn't powered on at any time during the storms. Besides all of that, we never lost any power to the house -- I'd assume it would have hit my normal firewall rig that was running if it hit my powered-off gaming rig. They're on different circuits, but :confused:

Of course the firewall rig is an old POS Pentium 166 (yes, the ORIGINAL pentium :p ) with an equally POS AT power supply. Maybe it's not near as sensitive?

Dunno, it made me sad :( I've talked to this same tech dude a few times and I even have his "home" Hotmail address. I told him if it wasn't warrantable I'd just have to go buy another one because I couldn't take the downgrade in options going to Asus or Abit or Gigabyte :p

Maybe he's biased? Or maybe it just really died? Dunno, sucked either way.

[fadaway0000]

Albuquerque I have some albtron questions for you? How much voltage do you think my 2.6c can handle? This board undervolt it seems and cpuz is giving these reading.

default 1.54v = between 1.472 and 1.488
+.10 = between 1.552 and 1.584
+.20 = between 1.16 and 1.648

Should I go higher or is it to risky? +.30V ?

I can get 255 fsb with .2 v to the cpu and .2v to komusa but can't get the ram to stock frequency. at 260 I locked up and that seems to be the max for the 2.6c . Any suggestions on getting this ram to stock speed or better since this board doesn't like overclocking at a 5:4 and crashes (Bios reset) when I do.:bang head

Is this the ram you guys are working with?

I can't speak to the Pro version; I have the Pro II and the voltage regulating hardware is quite different. You can certainly try the +0.30 setting, but I wouldn't advise that you keep it there. My BIOS / Motherboard Monitor reported voltages were actually lower than real life by a little bit -- I experienced very little sag even under full load when measuring with a true external digital voltmeter.

Several other components on my board are different as well, here's what I would suggest:

Keep the ram at 1:1
Adjust the timings -- at 255FSB, my ram was stable at 2.5-4-4-7 on 2.65v.
Enable PAT (Albatron calls it PEM) -- My board was perfectly stable at 255FSB at 2.5-4-4-7 while also using PAT.
Try replacing the northbridge passive cooler with an active cooler (I think the standard Pro unit uses a passive one)
Turn up the AGP voltage by one or two notches

Tinker with it... While 255FSB isn't the full speed of the ram, it had no problem belting out a ~5800mb/sec score in Sandra '04 and a screaming ~5400 read / ~2500 write score in Aida32. It actually scored better in Aida32 with the above-mentioned settings than it did at 284FSB with loose timings and PAT disabled. I also had to run up my AGP voltage by a few notches to get the board stable at VERY high FSB with the ram at 1:1.

The FedEx tracking number says I'm getting the new board today, so hopefully I can post back tonight with at least SOME news :)

[flapperhead]

last summer, b4 their pc4200 i bought 2x256 of the adata pc4000 hyperram. it runs 290+. however i would think the better adata sticks go to the pc4200. if u get some ,let us know how well it overclocks..

[KOXC2003]

But if i only need it to go 270 max.. probably only 265 would that be ok? "it runs 290+" Why do you suggest the pc4200 instead?

[flapperhead]

thats a good point. the only answer i would give is that the pc4200 is only 20.00-25.00 more and if u ever upgrade or need the extra speed it is definitely there. but u are absolutely correct, if u only need 250 or so the standard ram should be fine. oh yeah, one other point, the adata seems to get along with the various chipsets better than alot of the other ram..

edit: Im kinda curious how far the standard stuff will run..

My new board is here; it's memtesting right now at my previous settings of 284FSB 1:1... I have already noticed something, I needs less AGP voltage to run the newer board at this speed. I also just quickly tried a few settings, and my previous board wouldn't even post with PAT enabled over 265fsb... This one will allow me to set PAT here at 284FSB (although it's not at all stable at that speed :) )

I'm gonna let it memtest for a while tonight, and I'll do some more playing before the weekend.

just finished soldering an extra cap on my ic7, working on 2nd mod, higher agp voltage, involves cutting a trace and adding components. what a pain!i got 3 more mods left after this. I hope this stuff is worth it.

oh it will be worht it

[Albuquerque]

I'm a little more skiddish on voltmodding my just-replaced board. :S It'll take me a few more weeks probably to get the cajones grown back before I decide to think about it :)

But if i only need it to go 270 max.. probably only 265 would that be ok? "it runs 290+" Why do you suggest the pc4200 instead?

people suggest the pc4200 because it most likely gets the better ram chips, which most likely OC higher. its like P4 processors. most of them can do 3.2ghz, but the ones that cant are bound down to 3.0, 2.8, 2.6 and 2.4ghz. there is only such a market for 3.2ghz cpus, so since a lot of them can do 3.2ghz, they are still bound to the lower speed cpu's because they cant have 3000 3.2s and only 100 2.4s, the 3.2s wont sell. this is why the 2.4s OC so good, they are higher chips that are downgraded, and a 2.4 is prefered because you can get high FSB speeds.

so if you need the headroom in the future, get pay the extra $20-25 and get the pc4200 and underclock it to what you need with a bit tighter timings, and if and when you do need the extra speed, it will be there.

yo Albuquerque! check your pm's! :D

you have email turned off so this is my only course of contact. hope it works.

[flapperhead]

Albuquerque, guess what i just got my hands on????? a 2.4c guarenteed to 3.7...goody goody goody... i can hardly wait to mate it up with my 5 in 1 modded ic7... now finally after 6-1/2 months, i can test this ram to its max..... It costed a pretty penny,(230.00) but i dont care, heheheheheh. (jeeesh i used to only get this worked up over girls, lol) wish me luck on my quest for the hollowed grounds of 300+ fsb and 1-1 memory guy...

[Albuquerque]

I'll go check my PM's right now; I haven't received any notifications, and I purposely leave those enabled because I never think to go look on my own :p

As for the 3.7ghz 2.4C... DAMMIT BOY! :D Why are you posting here and not out there overclocking your little board to death? :p I wish you all the best, it looks like I'm having problems now with my replacement Alby. This one is giving me REALLY bad voltages on the CPU.

Get this: 1.6v in BIOS = 1.55 reported in MBM and about 1.58vcc in real life -- but my AGTL voltages (you know, that second CPU voltage that's supposed to be just slightly lower than vcc?) is at 1.81v :eek:

I eventually found that while trying to figure out WTF was going on with my CPU temps. It keeps idling at like 46c even at stock speed while running my Swiftech MCX4000 sink and a Y.S. Tech 80mm fan! Hell no wonder, I'm feeding it 1.8 volts!

I just figured this out about half an hour ago, so I'll be calling Albatron first thing in the morning. I'm posting this from my podunk laptop; no way in hell I want to fry such a great chip with a screwed up board.

Maybe third time is the charm?

[flapperhead]

actually i just bought it, so it should be shipped by mon or tues, i was so worked up i posted like i already had it.. man i gotta get those mods done asap... good lord 1.8v yep u had a little heater there.. i also have an mcx 4000 with a 120 cfm tornado plus im suking cold air in from outside via ducts with an additional 130 cfm fan. right now its 27c at 1.66 volts, jeesh al, sorry to hear about youre probs with the boards, yaknow, some of the guys swear by the 875 chipsets claiming that at extreme speeds they just seem to be more stable.. also i know the asus also feeds voltage to the nb as u increase vcore, maybe a decent reurb from
newegg? would help... anyway youre a good guy and i wish u a ton of luck, getting the the probs worked out... flapper...

[mattspalace]

Giving this thread a bump as this is some very good memory, and I don't want to go searching for this thread eventually. Currently 288FSB with 1:1 ratio.

[mattspalace]

Oh yeah.. I have a 2 x 256 kit of Adata PC4200 on the way.. I'm curious about the overclocking differences between a 1GB kit and a 512MB kit.

[flapperhead]

I would think at least 5-10 mhz benefit .my stuff runs 290 np, then my cpu dies..

[mattspalace]

Yeah, I need to set a 5:4 ratio and 300FSB - just to see how well my CPU is doing..

[DMC8260]

I have noticed something really strange here.
People with 2X256MB PC4200 Adata ram will most likely to hit 300FSB+ then the people with 2X512MB stick.... Also for Asus P4C800-E board, what ram can run 5:4 ratio up to 280+FSB??? SInce I have a pair of Hynix PC4200 they run 280FSB rock solid at 2.85V and when I try to run them using 5:4 at 280FSB... my comp just won't post at all!!

[Sophisticated]

mayb u should lower your voltage to them because they are way underclocked to 448MHz @ 5:4 280FSB so try the Vdimm range of 2.6-2.7
