G.SKILL Extreme Series 2GB (2 x 1GB) OC Report

[dominick32]

I had to post this review for one reason. Newegg is currently shipping the GSkill Extreme Series PC4000 2-Gig sets for $157 with no Mail In Rebate, only an instant discount.

G.SKILL Extreme Series 2GB (2 x 1GB) 184-Pin DDR SDRAM Unbuffered DDR 500 (PC 4000) Dual
Channel Kit System Memory - Retail
Model #: F1-4000USU2-2GBHZ

http://images10.newegg.com/NeweggImage/productimage/20-231-021-02.JPG

Over the last month I have been through 4 different memory sets: Corsair XMS PC3200, Team Xtreem Micron, Team Apollo TCCD, and now currently the GSkill 2-Gig set. I am trying to figure out what set is best for my system. As far as absolute overclocking potential is concerned I vote my TCCD Apollo sticks. I achieved a 315mhz fully stable overclock with them. The down side and reason for my switch back to 2-gig dual channel is that some of my
games wouldnt run correctly in Ultra Quality/High Resolution settings. The ram would immediately run out and shove a gig into in the page file. Ex: (Quake4, BF2) Right now, the GSkill in a price to performance ratio is unbeatable!! With the price of high end dual channel 2-gig kits going for upwards of $200 and even close to $300 for the newer -5b f modules I was a little disheartened after obtaining results of 282 mhz with absolute EASE on my GSkills.

The other high end modules in question, costing upwards of $250 have been clocking in on average at 260 to 275 mhz based on my most recent observations on multiple online forums. I do have the latest run production GSkills the "0603" serial number and I have a hunch that newegg.com has a crap load of the same exact "0603" binned stock that I received. For a price of $157 I would highly recommend these sticks.

Another important thing to note is that these are not cherry picked. I simply pressed the "Buy it now" button using Newegg.com. That means that my results may be average for many of you buying the same ram set as me. "Please note the words: may be average"

On to the results. I always test out my ram initially with stock rated timings and no adjustments in the bios or using A64Tweaker. I like to see how far I can push the frequency without touching a thing.

First test: 250Mhz 1T (3-4-4-8) 2.6v Memtest Stable in dos for 5 runs on test#5, Superpi32m stable.3D gaming stable (BF2,Q4,Farcry)

http://www.strippoli.com/ocforums/gskill250.JPG

Second test: 275Mhz 1T (3-4-4-8) 2.6v Memtest Stable in dos for 5 runs on test#5, Superpi32m stable.3D gaming stable (BF2,Q4,Farcry)

http://www.strippoli.com/ocforums/gskill275.JPG

Third test MAXIMUM STABLE SUPERPI 32M OVERCLOCK, VOLTAGE RAISED .03 Points in Bios: 282Mhz 1T (3-4-4-8) 2.65v Memtest Stable in dos for 5 runs on test#5, Superpi32m stable.3D gaming stable (BF2,Q4,Farcry)

http://www.strippoli.com/ocforums/gskill282.JPG

Finally, I strapped down my normal processor overclock settings and finally achieved my goal of getting a 1:1 memory/cpu setup of 10 X 280 (2.8Ghz) 1.52vcore :) The results are excellent bandwith at stock timings and settings and great 1:1 setup.

http://www.strippoli.com/ocforums/gskill280maxcpu.JPG

Thank you GSkills!!
Now its off to adjusting all of the timings in A64Tweaker to get the absolute maximum out of these.

Dom

Very nice looking for memory Dom, especailly at that price. You could have 4GB of these Gskills for what my Ballistix cost.

Could you tell me what your superpi times are for 1M and 32M at 280MHz 1:1? That is exactly my overclock atm with my X2 (differing cache sizes though) and I like to see what effect the memory timings have between our kits. I'm still running the Cronus atm which should perform about the same as my Ballistix at 3-3-3-7.

Thanks for the response Mustanley. My 1M times are usually 29 seconds, with an occasional 30 if I am internet browsing in the background. My 32m times are usually around 26 and 1/2 minutes, give or take a few seconds.

[mynihilism]

any one know if its compatable with an A8N32-sli ?

i f#(ed up and bought some corsair xms pc3200.. needless to say i'm returning it to new egg because it would crap out at 210mhz.

165 opteron going to 2.4ghz+...... yeah stupid move on my part.

I'm REALLY interested in this ram especially with those numbers.

I received my sticks on Wednesday. For some strange reason, I can't get them to boot into Windows. I can't figure it out. I was trying for the past two nights to get them to work. I even reset everything to optimized settings. No take. I ran memtest86 on it a few times (test5) and everything looks good. I get the Windows swishy bar load screen, but when it tries to get into the OS, I will either blue screen or the machine will just reboot itself.

As far as I can guess, my BIOS revision is too old, my OS just doesn't like me, I'm using the wrong slots (orange) or there is something I'm forgetting. Tonight I will probably try installing a new OS on a spare drive to see if it's just the OS. I'm guessing no matter what, I should really install a new BIOS... Got any suggestions?

I am using the 11/14/05 bios. The newest revision. Try testing sticks individually as well. It could be that you received a faulty stick. This happened to me recently with a Micron Cronus Purchase. Good luck!
Also, what bin stock are your sticks? 0603?

Dom

[Luftwaffle]

How do I check the bin? I'm at work right now, so I can't do anything till I get back later tonight. :T

I'll surely give the one stick at a time a shot. I think I tried it before, but the motherboard wouldn't post and started beeping angrily at me. Also, when I replaced all my old TwinMOS RAM, it wouldn't post until I switched sticks. Like literally, I had to put one stick in the slot occupied by the other or it wouldn't post. What's up with that? I think my computer is crazy.

The production number will be the first four digits of your serial number.
Example: Serial# 0603XXXXXXXXXXXXXXXX

Keep me posted with updates on your situation. Another thing, after looking at your bios version. It is definitely way too old! Off subject: I dont even think the Ultra-D has X2 capability until the 6/23/05 bios. On subject: I am aware of many ram compatibility issues being fixed through upgrading to 6/23/05 or 11/14/05. I would definitely give this a shot before anything.

you haven't had any issues with it on your A8n32 then? been stable and reliable?

Well, go out and buy them before Newegg.com raises the price based on demand generated from my review. No joke here: Newegg.com actually raised the price on WD74 Raptors after my Raid0 Raptor review( http://www.overclockers.com/articles1297/index03.asp ) displayed promising results. I must have made 100 people go out and buy a second raptor. :santa:

i actually wen tback to stock 3-44-8 cuz of random errors...but its all good everest gives me 7200est bandwith and sisoft gives me around 6200megs

[inkfx]

You got a nice set there. Mine seem to stop around 270mhz.

[avalanche83]

That is definitally a nice set there. Especially pushing 1T.

Avalanche, Ink,
Thanks for the remarks.

**UPDATE**
I did it!
Finally broke 12,000. Thank you GSkills!!
I raised CPU/RAM to 10 X 277 = 2.77 Ghz 1:1
Raised GPU core to 690 and memory to 732. For some reason with previous testing my memory craps out any higher than 740. Anyway here is is:

Congrats on breaking 12k! Can you bench at 280x10?

Congrats on breaking 12k! Can you bench at 280x10?

My computer is stable @ 10 X 280. It completes Super PI 32m no problem, and runs dual prime no problem. But recently my PWM IC temperature has been climbing to 52*C under load. Lowering my speed to 2.75 to 2.77 keeps PWM IC temps just below 50*C under load. Until I figure out a way to mount some fans over my power management area on the Ultra-D I am going to keep the clocks below 2.77 ghz. As far as benchmarking, yeah. No problem whatsoever running 3dm05 at 10 X 280. :)

[Luftwaffle]

It was a rather harrowing weekend, but I'm back. I managed to at least get the sticks to work, but my computer ate my nVidia RAID driver diskette in the process and all the drivers on DFI's site cause errors during the windows installation... Dammit.

Dramatics aside, I've only managed to get 260Mhz at stock timings and stock voltage. At 265, I'll get 4-16 memtest errors per pass in test 5. At 270, I'll get a lot more errors, and at 280, forget about it.

I'm binned at 0603. Maybe I just got a pair of weak sticks? Dom, do you have a fan blowing down on your memory?

Do you have something like a house fan you can put next to your case just to keep it down during benching? Thats what I do and it drops my temps by like 7-10c. If you dont want to do that you could always buy a new heatsink for it.

I think my best bet is going to be mounting two 72cfm fans a few inches over the power management sinks. This seems to be the best bet to dramatically lower PWM IC temps. I would like to keep my rig stable @ 10X280 all the time, so the actual mounted fans are a necessity for me.

Man,
Thats dissapointing to hear. You sure the bios is set @ 3-4-4-8 timings? I know a trp of 3 causes massive amounts of errors for me at anything over 260 as well. Can you boot into Windows and post up a screenshot of A64Tweaker? Maybe the DFI bios is shooting some random automatic settings into your sticks causing instability. Example: Weird DS/DDS settings or a wrong twcl setting. <---- This number impacts my sticks dramatically on anything other than 1.

Let me know.

Tonight, when I get home, I'll try setting everything in the BIOS to the settings you have on your CPU-Z screen. The timings are the same as yours, but some of those numbers on the bottom are different, namely the Trc and the DRAM cycle times. If it's no go, I might RMA them and get a new pair.

Yes, I'm running them on my setup at 265 1:1 and have yet to even push it.

I hope I'm no patronizing you by giving you the following. just in case, check to see if your settings are near where mine's at. Perhaps this would allow for slightly higher clocks than the 260 you've received.

Look for my post with settings in the below link.

Personally, I'm willing to try anything at this point. I really don't want to RMA the sticks. Thanks for the suggestion. I'll give it a shot when I get home tonight. :D

i bought these the other day when i saw the kit listed in "cyberdeals" should be getting them tomorrow... will let u know what i get out of them.

Definitely keep us posted. I am hoping you achieve the same max OC as me. The ease of obtaining a 280 mhz OC with these sticks only led me to believe that I did not have a "lucky set" but that the new 0603's are actually averaging 270 to 280.

But seeing some of the results from others within this thread led me to believe that maybe my set actually was lucky. Maybe your results will be on par with mine, than I can throw that theory out of the window. So please, as soon as possible post some positive 280 1T results!! :p

not to kill the buzz... but my board/cpu maxes at 275... and it's on an Epox 4pca3+ (intel 875) i'll be ablr to test the timings... but i cant select 1t or 2t...

but u can bet in a few months when i go socket 939 i'm gonna max these out!

well i just came to this forum to question the quality of my sticks and ran into this post, so this is probably the best place to ask. i was running my system at 285x9 with the g-skill DDR500 ram @333 on my Asus a8nsli board, but i was having stability issues and decided since i rarely use my CPU past 80% usage i would just back down to 250x9 and run the ram sync at 400mhz which resulted in 250 frequency on the ram, and it was at this point i realized my ram cant even boot into windows at stock timing. i tried memtest at 250 and it failed in the 7th test and i stoped at that. would you say its time to get an RMA, or am i doing something wrong possibly.

I dunno about your motherboard, but I have the A8n32-sli and it detects this ram at 3-5-5-10 for some reason or another and with those timings its really really unstable and will fail at the 7th test in memtest, atleast it did for me. So go into your bios and try manually setting your timings to 3-4-4-8 and see if that helps.

[Cow Hunter]

hmm now that you mention it, take a look at these shots and maybe someone can help explain them
http://web.bryant.edu/~cjs2/ram.JPG
does the SPD page tell me what my ram is suppose to run at and the memory page tell me what it is running at. right now i have it set to manual in the bios from when i had it running it unsynced at 333mhz, and i just changed it back to 400mhz and the timeings are still set to 3-4-4-8 manualy. i guess i will try to set it to auto and see what happens. And these shots were taken at 333mhz, hence why the memory is running at 225 and CPU at 275

UPDATE: ok i tried Automatic ram settings and it put the ram divider to 266mhz, so then instead i tried 250x9 at 400 divider with timeings 3-5-5-10 and it blue screened just after entering windows, which is what happens every other time i try to boot up at 250 with synced ram.

[protocol_droid]

SPD is showing the details of the ram you have and its rated speed at stock (1:1).

The memory tab is showing what your ram is actually running at.

[inkfx]

Dominick, ive got a few questions for you if you dont mind. Id like to start by asking what settings you are using for your ram in the bios. Im pretty new with DFI and am not sure what most of them mean or do. So id love any help you could give me. I set my twcl to 1 like you and put my Trc at 15. By doing that I was able to pass Memtest86 test #5 5 times with no errors. I tried for 275 at the same settings but no luck.(only had 2 errors) Im sure with a little more tweaking I might be able to do it. One thing I find wierd is that even though Memtest passes I still cannot boot into Windows at 270x9. I set my HTT multi to 2.5x so im definatly not going over there. (ive been using 2.6v since thats where people seem to have the most luck)

The highest ive tried to boot into Windows is 265, here is a screen shot:

[dominick32]

Ink,
What is your Drive Strength, Data Drive Strength (DS/DDS) set at? Weak or Normal? Take a look at my screenshot of A64Tweaker. It has all of my current settings. My settings are ultra conservative and for stability, nothing more. Like I said in my initial post, with automatic settings and manually setting 3-4-4-8 in the bios I was able to boot up into Windows with full stability @ 282mhz. Another thing to remember, I am using a Toledo core x2 4800+ processor with a great memory controller that has no problems handling my ram at high mhz. There is always a chance that your actual memory controller is having problems with it.

http://www.strippoli.com/gskill282.JPG

For the users questioning the SPD tables in CPU-Z, dont worry about the numbers. You need to manually set your timings to 3-4-4-8 in the bios. Its no wonder some of you were getting problems booting into Windows. :p

Another thing, for the two guys having issues: What is the production number on your modules? 0603? To find this number, look at the first four digits of your serial number either on the sticks or on the packaging.

Cow Hunter, download A64Tweaker and post up a screenie of your current ram timings. I want to see how your numbers look. You are definitely doing something wrong. If your sticks will not even boot at 250 mhz, rated timings and voltage I would definitely RMA them. But after reading your post it looks like you are simply doing something wrong. Maybe a small setting in the bios is incorrect.

Cow hunter,
Try running your ram at 200 mhz 1:1 (no divider) and clocking your FSB/HTT to 280 mhz using a 6X or 7X multiplier on your CPU. Get your CPU out of the equation and see if your ram is capable of 280 mhz. If this does not work, try using my "extremely relaxed" A64Tweaker settings in your bios and let me know what happens. I think you should have 280+ mhz out of your sticks. Keep working at it bro.

Dom

[Luftwaffle]

Does A64 Tweaker automatically pick up the RAM timings and stuff from the computer when you run it? I tried it last night and it was spitting out some crazy settings... I'll take a screenshot tonight. I wasn't able to do much last night.

Yes,
A64 Tweaker should automatically take all of your bios settings and display them fluidly on the windows xp desktop.

DS and DDS are probably both set to normal. Maybe this s754 just can't handle those speeds. I suppose ill have to wait till I get my new rig before I can see what this memory can really do. Thanks for you help.

[Thoth]

So.... i finally got these... the UPS man just left my babies on the front porch :rolleyes:

anyway... after testing them out a bit... i think i've hit a wall on my MB... the reason i say this is... i can run stock timings and voltage from 250mhz up to 269mhz... and everything runs peachy... i can run all my games... (super pi 32m running now) ...

but as soon as i cross 270mhz... the comp freezes something nasty in memtest... no errors... just freezes... and usually 2-3% into the 1st test... increasing voltage doesnt help... (i know this stuff likes low volts) 2.7 and 2.8 dont help the stuation any... i was already stuck at 275mhz @ 5:4... and now it seems at 269mhz @ 1:1...

since i have a i875p i don't have the mem options u (a64) guys have... but with the bit of tweaking i can do (i875p tweaker) i got some nice results out of it...

i have another MB i could test it on... but i don't think it'd matter.. as the MB is a Shuttle with limited vcore (limited vdimm doesnt matter now that i got these bad boys :cool: ) and i don't think i could get up to 270mhz fsb anyway ... so i guess i've just gotta sit on these sticks till i go a64...

(btw... do have an 80mm fan over these... even @ 2.6v they get toasty without a fan)

Edit : even if i cant get 275 1:1 on this old board... the jump from 1gb to 2gb makes this worth it also...

Edit2 : Super Pi32m Stable @ 269 3-4-4-8 2.6v w00t

[eric003]

I'm recently picked up those GSkills for my new build, I am just starting to OC them. I got mine from Newegg just like you Dom..they also have the 603 serial.
So far I have gotten to 260 stable. working on 265 right now. I booted into windows at 265, but PI showed errors, and I also got memtest errors. I just found this post, so tonight I will check those timings you posted, Dom, and see what I can do.

CPU: AMD OPTERON 170 (currently clocked at 265x8 1.375V)
MB: DFI NF4 SLI-DR EXPERT
RAM: GSkill PC4000 HZ 2.6v (3-4-4-8)
GRAPHICS: EVGA 7900GT CO (newegg)
Swiftech WaterCooling on cpu, gpu, chipset

i tried setting my timings and everything similar to yours Dom with A64 tweaker and choosing the option apply settings at startup, but it didnt seem to work, and unless i am not looking hard enough the asus board doesnt have much more than the basic timing settings found mostly on the left half of A64 tweaker. i lowered my HT to 3x and CPU multiplier to 6x and i still failed Memtest at 250mhz

also whats up with the Refresh Rate (Tref) being 100mhz, thats one of the settings i couldnt get to stick properly. incase you havent noticed this is my first time using A64 Tweaker, and i never really went far past adjusting the 4 main timings before

DS and DDS are probably both set to normal. Maybe this s754 just can't handle those speeds. I suppose ill have to wait till I get my new rig before I can see what this memory can really do. Thanks for you help.

Ink,
I am banking on the s754 having a lot to do with your OC'ing issues. I am almost certain that these new 0603's are clocking 270 to 280+. Keep me posted and send me a PM when you get your new rig up and running. I am curious to see what a motherboard/cpu swap will do.

Eric003,
265 is a great start. Sometimes these motherboards are just very finicky with ram settings. Just a quick example on another set of sticks that I tested. With my Ultra-D and the Team Apollo 2X512 TCCD: The difference between a DS/DDS of 5/3 and 7/3 was complete superpi32m and memtest stability vs. an almost immediate failure of superpi and over a thousand errors. That is just one example of how finicky motherboards and ram can be sometimes. Simply changing my Drive Strength to 7 vs. 5 made a huge difference. With highly tweaked settings I was able to clock those TCCD sticks to 315mhz and boot into windows with spi32m and dual prime stability :p but thats another story. Keep working and make sure you continue to post your results in here.

Cow Hunter,
It seems as though you may have a bad set of sticks. This stuff happens every once in a while. First I would give GSkill Tech Support a call and see what they have to say. If nothing pans out then I would send the sticks back under RMA and make sure to state "They will not run at the rated speed, timings, and voltage: DDR500, 3-4-4-8, 2.6v" Based on that last quote, you should be able to get a replacement quick from any of the vendors or the manufacturer. I would prefer going through the retailer because chances are they will expedite a replacement much faster than a manufacturer.

Regards,
Dom

[Cow Hunter]

yeah i will just have to RMA it through newegg this weekend when i can get my hands on my old ram to use in the meantime.

Edit: it turned out to be my motherboard, not the ram, so dont let my posts stop you from buying this ram :P

[ou_phidelt]

Looks like newegg finally figures out they were selling them for alot cheaper than they could get for them. They are back up to 192.00

okay, I was able to get it stable at 265 :) now for 270...

http://www.unix.eng.ua.edu/~kneyn001/pics.htm

[eric003]

ok, i got 270 :D (took quite a bit of work though...lol, for giggles, check this post's time stamp, with my last post's time stamp)

Anyway, stable in memtest...trying PI right now... will prime over night i think..
*One thing I noticed, is that even at 2.6V, ram gets hot to touch... So I put a 72mm(?) maybe its an 80mm :shrug: idk blowing over ram, now its only warm to touch :cool:

Here is a link that I found over at DFI Street. THIS LINK IS GREAT! :D

it explains all the crazy memory settings for DFI NF4 mBoards! This link really helped me to understand the what i was doing when tweaking the settings..knowing which was a tighter timing, and which one is a looser timing and better for increased Freq headroom. It very much led to my succesful 270 posted above :D

[HousERaT]

yeah..... I bought them yesterday..... delivered today. I got in on the last day of the deal. Seem to be pretty stable right now in memtest at 273 3-4-3-8. I'll be playing with these throughout the weekend.

275 to 285 mhz 3-4-3-8 and superpi32m and dual prime stable = $157 :shrug:
I guess a representative from Newegg finally found my thread on OC. lmao. :p

[HousERaT]

They were on sale for a good while...... I'm sure they'll put them back on sale soon enough. Still, I'm glad I got them when I did. I love the fact that they run with so little voltage. Great for people who run rigs in warm weather climates. I'll see if I can get them to run 2.5-3-3-7 up to 250 and 3-3-3-8 up to 273. Those will work great with my 150 Opty.

Thats some kickass ram!

Is that a max stable so far? I thought you were at 273 before?

Dom

[HousERaT]

that was just in all the memtests..... now I'm starting to work within the OS. I'll do some more tonight. There's a good chance I might be able to get 3-3-3-7 stable up to 273 in Windows, which is what I really want. People have been able to get some good timings with this ram.

I havent even tested straight 3's yet with any kind of realistic Mhz. I tried 3-3-3-7 @ 280 Mhz. :p and it crashed on the XP desktop. But I am enjoying 3-4-4-8 @ 280mhz dual prime stable. Maybe I will try for some 275 @ 3-3-3-7 tonight.

[=ACID RAIN=]

I got this kit in yesterday and fired it up immediately at 244MHz (current overclock on my 1GB kit) and it seemed fine. I'll be tweaking it over the next few days, I'd like to hit 275-300MHz 1:1. I booted at 275 but it showed errors in windows.

so far so good, testing with superpi right now then some gaming later.
i'll see how far i can get it this weekend.

THANKS dominick for all the info, the install would have deffinitely been a pain in the ass tweaking all those settings on my own.
I'll make sure i have one for you at the bar tonight in thanks for your efforts. :)

[HousERaT]

Here's another update..... 3-3-3-8 was a no go at 2.54v or 2.64v@268. I don't want to fry my UCCC just yet so I knocked down a few more of the timings. Took 4 seconds off my time.

[Nevalite]

Is this the same ram:

It seems to be the only place I can find in Canada but that price is really high. Anyone know another canadian retailer that stocks g.skill?

That price seems pretty steep. Maybe you should find someone in the U.S. willing to buy these sticks for you and ship them over.

OMG I spent literally ALL night last night working on this ram and the $@&*&^% Memory timings... :bang head :bang head :bang head
http://www.unix.eng.ua.edu/~kneyn001/pics.htm

pretty much I have read so much info about ram timings it unbelievable. unfortunately, all this info just lets me realize how much of this process is trial and error. I tried forever to get 280..with no avail.. kept getting 41,000 errors in memtest.

So I instead concentrated on 270 with tight timings (on the other stuff, not the normal 3-4-4-8)

I think I will start on the cpu now...

270 is a great spot to be at. Remember, not all of these gskillz are going to be guaranteed overclockers. Assuming you received decent sticks from the manufacturer I figure that 270 to 280 mhz would be about average on the new 0603's for someone with decent OC'ing knowledge. So you are right about in the ballpark. Nice OC! :)

Dom

[eric003]

thanks Dom :) I just spend another couple hours tweaking after I hit up the forums. I got them to run stable at 270, but this time at 3-4-3-6. [with the other settings same as before] still at about 2.61V

One thing that I find odd, is that I will get errors in MemTest86, but I can pass super PI 32M and Prime 95 all day... ? any thoughts? and not just like 2 errors, like 30 errors..

SuperPi 32m and Prime95 stability? Dont even think twice about those 30 or so errors in Memtest. Overnight prime stability can give you some nice assurance that your sticks are perfect at that frequency-270mhz.

[demidrol]

my G.SKILL are coming this monday, so I think I'll have few question on oc and checking if my memory is OK, but for now I'm wondering can I test my gskill in my HP system if it works before I disassemble my whole system?

[Albaholic]

aww crap, i wish i had a pair (of this ram) Price is back to normal :(

[JasonBr]

Cant seem to get Super PI to pass 255 with mine.
Mine are even 0603's

Tried voltages 2.5-2.8 dont make any difference, except 2.5 seemed to be less stable.

Timings atm are as follows:
Cas 3
Tras 8
TRP 4
TRCD 4
TRC 12
TRFC 12
TRWT 4
Have a DFI Lan Party SLI-D MB & AMD 4400 X2

you might want to fool around with the drive strengths and the max async latancy as well. Depending on your sticks there's more to overclocking memory than just changing a few timings.

Nice results HousERaT:D

So are these the sticks to go with for 2GB's? I'm looking to upgrade my pitiful amount of RAM. lol.

[HousERaT]

Well they're not on sale any more so I'd say to go for whatever you can find cheap. These happen to be from a really good lot of UCCC (according to GSKill Technician over at XS). OCZ has a nice rebate for a 2GB set over at Outpost right now.

Nice OC's HouseRat! :)

I have little doubt I can get these sticks well over 280. I just don't have any need to do so at this point. These are some darn good UCCC.

[dominick32]

Anyone experiencing any cold boot issues with this ram and the Ultra-D mobo? For the last week or so, my computer started having problems cold booting. It will fully power up the HDD's and fans, everything but the monitor and the PC will freeze before post.

A simple depression of the reset switch will remedy everything and boot up the PC. I would only happen a few times a week, but lately it has been happening almost every boot. The ram is fine, I have tested it and pushed it well beyond physical limits as well as my CPU overclock.

This is not a stability issue as I can leave the computer on for days at a time at my current cpu/ram frequency and voltage with no problems it is only an annoyance. Anyone else experiencing this?

[HousERaT]

The only time I ever experienced anything like that was when I tried to run them in the yellow slots. Otherwise it's all good over here.

[Slammin]

Just a guess because the problem went away before I could conslusively nail it down, but try dropping vdimm and see if that helps.

[dominick32]

Just a guess because the problem went away before I could conslusively nail it down, but try dropping vdimm and see if that helps.

My vdimm is currently at 2.6 volts. You think dropping it to 2.5 would be a plausible solution? It may not run @ 280 mhz at 2.5v

Dom

[Thoth]

first of all lemme say that this Epox Motherboard's memory dividors are the most CONFUSING thing in the world... memtest apparently doesnt like memory frequencies above a certain number and makes 300mhz (ddr600) look like 150mhz (ddr300)... so... yea... here's the pic alrdy...

http://webpages.charter.net/rbeitzel/good-i-think.jpg

if i can figure out how to work the dividors i think i could get more...

the bios is set to 250mhz fsb 4x htt... mem set @ (ddr466) 233mhz... and i have NO idea how the heck it got 296mhz on te ram... :shrug:

mem voltage is @ 2.7v i think....

[Mustanley]

It's difficult to calculate your mem speed when running half multipliers. Try running at 9 or 10 instead of 9.5. I know that on my DFI board, even if the ram and cpu ratio are at 1:1, running a half multiplier will force the memory to a lower divider.

[Thoth]

mem voltage was @ 2.6

i looked through the "a64 101" and found out a bit better how to work the multipliers... as soon as i find the ceiling for the cpu i'm gonna work on the ram again... i tried the same settings as in the scr shot at the next ram divisor up... which would have given me 312mhz (ddr624) and memtest kept freezing... so... my max is prob somewhere between 296mhz and 312mhz... hopefully above 300mhz... w00t!

one thing... i thought 1t was like not supposed to work above a certain mhz... i booted up @ 296mhz with 1t just fine...and its blazing fast in sisoft too... like 6600mb

[Cow Hunter]

i would just like to update my status. way back on page 2 of this post i complained that my ram wouldnt run even at 250mhz stable in my system. well after finally having the time to get spare ram so i could RMA it, i ran into worse problems running my back up ram. i went back to step one and tested each of my sticks individually and they ran properly, so i tried the 2 back up sticks in the other 2 dimm slots and problem was solved. it seems my dimm A1 slot is broken in some way, so now i got my 2 G-skill sticks running in dimms A2 and B2 at 250mhz fine. they memtested all night without any error, so i think it is ready for some overclocking, but the rest of my computer isnt. I am still getting crashes while playing world of warcraft, but each night i leave stress tests up to try to crash my system and i never do, so i am still evaluating if i need to buy a new powersupply or not before i get back into overclocking past 250mhz.

[Nevalite]

Just to let everyone know, it seems that the ram is back on sale!

http://www.newegg.com/Product/Product.asp?Item=N82E16820231021

I am really tempted to upgrade to these bad boys... :burn:

[Sniper.nkc]

I bought the HZ when they where $195. I can run 270 1:1 with my X2 3800. I did a memtest86 on each memory seperately and guess what...I have a memory that can run at 285 with no errors and I have another that can run at 275. Damn, I wish these two can run at 285. I don't understand why buy a dual kit when each one is different. Memtest86 and my overclocks on a dual channel will fail on the weakest ram @ 275. I like to trade one and get another that can run @ 285. Has anyone experienced this?

[=ACID RAIN=]

You're overclocking them man, it's luck of the draw. They guarantee 250MHz, not higher ;)

I'm right on par with 250MHz due to a 183 divider on a 300MHz bus, but they run fine at around 270 for me. I tried 300MHz but got errors eventually in memtest. I think I could tweak to near 300 on the ram, but I want to keep my bus at 300 or higher so I'm staying where I am currently.

[eric003]

how much of an performance improvement did you notice ACID RAIN, from giong the whole divider route. with a 300mhz HTT. Cause i am thinking about doing the same thing, as i cant seem to get past 270 on the ram. I was thinking maybe 300x9, or 333x9, or 333-375x8

[=ACID RAIN=]

Basically with the A64 chips, sync'd ram is not as important on the nforce chipsets as it was in the socket-A days. Do whatever it takes to ramp up the bus speed and overall CPU speed, with whatever being your closest to CPU max with highest possible bus being the best option. In other words, 300x9=2700 would probably be better than 275x10=2750, even if there is a memory divider in place. At 300, for instance, a 183 divider would give you 250MHz ram, which is perfectly fine for A64.

This "bus vs multiplier" rule may be less evident on A64 platforms due to structural changes of the system overall, but I do not know that for sure. I do know however that rule above would definitely apply to socket-A or any other platform with a northbridge. So in theory it should be the same for A64 as well.

Go for the divider, it won't hurt you as much as you might expect.

[eric003]

yeah, i read over at dfi streets, an article by angry games, about the pros/cons of dividers. And it seems that the dividers had absolutely NO negative impact on performance. as far as 306x9=2754 vs 275x10=2750. obviously you get a boost from running your ram higher, but if you cant run it higher, then achieving a higher HTT seems like the best scenario. and to an extent can be more beneficial then higher mem clock (which can be compensated for, in turn, by using tight mem latencies)

[eric003]

I forgot to mention, i have a DFI expert, which some people have achieved crazy HTT speeds...in excess of 450... :drool

[Velocity]

Will this ram work on my current motherboard?

[Nevalite]

I don't see why it wouldn't.

[dominick32]

Little update for tonight.
I tried pushing the envelope tonight.
Got it to boot @ 297 mhz, 2.76 volts, Drive Strength/DDS @ 7/3
It immediately BSOD's after a few seconds cruising on the xp desktop. I didnt have a chance to open up sandra.

Tried running memtest. Thousands of errors appeared.

I slowly came back to down to 290 mhz, was able to operate with the same settings at 2.76 volts and use XP flawlessly. Memtest produced 38 errors and superpi32m failed so I went back down to 286 mhz, no problems whatsoever. These sticks are really impressing me. Finicking with DS/DDS and voltage gained me 4mhz stable from 282 to 286.

[Sniper.nkc]

Very nice clocks. Glad to see you get that high. You are very fortunate. :p BTW, what is Drive Strenght/DDS 7/3? Can you provide more details on this and where the setting is? Thanks.

[Seinken]

Wow that's really nice, I was going to buy a low timing set of these but that had a 50$ rebate that would have taken forever, looks like I'll be buying these tonight!!

Will definetly update on how far mine clock =P

[dominick32]

Very nice clocks. Glad to see you get that high. You are very fortunate. :p BTW, what is Drive Strenght/DDS 7/3? Can you provide more details on this and where the setting is? Thanks.

Yes. It stands for Drive Strength, Data Drive Strength. Hence DS/DDS
You need to go into the Genie bios options in the DFI Bios. Select DRAM Settings and you should have the ability to configure all ram settings depending on your motherboard and bios version.

If you have the capability to adjust all ram settings you will see a selection for: Drive Strength and Data Drive Strength that will be on "Automatic" from the factory. If you are a noob to memory overclocking I would definitely read up on some of the information in these forums before tweaking any of these settings. It is very simple to cause complete instability with a wrong value.

PS- You can also adjust these settings on the Windows XP desktop using a proggy called A64Tweaker. Download it. :)

Good luck and keep us posted.

Isnt that what this thread is about? hehe :santa:
I am commenting because it seems that almost everyone reporting results in my thread so far have displayed at least a 270 mhz OC which is outstanding considering the fact that we are not just dealing with another 1 out of 10 chance at a decent overclock. These sticks are proving to be generally good OC'ers right from the manufacturer. :cool:

Man I cannot get these buggers to do 250mhz, even with my cpu multi at 8x and my ldt multi at 2x they only go up to 225mhz =(

Any quick tips? I'm sure everyones sleeping atm and i'm tired as well... may mess with this tomorrow.

[Velocity]

I'm easily getting 250 now. Going up tomorrow. Do you have some nice cooling?

[Seinken]

11c load... using a super cold air conditioner in place of fans lol

edit: i think the problem may be PCI bus going out of spec, but i hear there's an alternative way to lock it?

It moves up with clockgen, and i get a bsod at around 230mhz.

Won't boot windows at 230 either, barely gets into windows at 225

Most people here including myself are using 939 mobo instead of 754. I'm not sure how well these will overclock. See if you could up the power on the mobo and see what you get.

[Seinken]

Yeah I'm gonna blame it on the socket type, I bumped RAM up to 2.9v and still no go... =( kinda sad but I'm really enjoying the benefit of having 2gb for BF2, completely smooth gameplay now and no crashes, at the very least i junked this crap valueram i had.

[Seinken]

Just a follow up -- I got it to run 270MHZ easily after loosening timings, setting drive strength to weak and max async latency to 9 w/ read preamble at 6

[Reefa_Madness]

Have you tried each of those modules individually to see if one is stronger than the other?

[HousERaT]

Just a follow up -- I got it to run 270MHZ easily after loosening timings, setting drive strength to weak and max async latency to 9 w/ read preamble at 6
I hope you dropped the voltage as well....... UCCC memory doesn't require a lot of voltage.

[Seinken]

Would it affect stability?

[HousERaT]

maybe/maybe not but it will sure reduce the life of your memory.

Hello

I just got my G.Skill 2GB PC-4000 set today. Have done some testing on my PC.
My PC is not up to date like you guys, but my ABit AI7 took them fine. I am not running the ultimate AMD 64, but a rather "older" P4 2.4C.
I was not sure they would work. Sure enough, The PC started and I got the PC as high as 275Mhz 1:1 on A-A-A-D-D. Could not get the memory to run turbo.
My scores are not that high. PC Mark04 Score: 4554.
My set of mushkin PC-3200 512MB set at 2-3-3-5 280Mhz 5:4 PC Mark Score: 4625

Thanks

Daniel

picked up a pair since they were on sale at the moment...its time to go 2gigs now that my x1900xtx and raptor drive are coming :D

[U|tim4T3z]

Just want to ask, does this gskill mem spoilt easily when raced higher than 250MHz?

[Janus67]

how does this look guys?

[EvilAerosolCan]

Does anybody else's run hot? I have mine at 260 3 4 4 8 at 2.6v, and it seemed very hot. Not burning hot, but enough to say "Wow that's hot".

[Janus67]

seems cool to the touch to me at 2.7v, then again i have my rad fans above the sticks.

[EvilAerosolCan]

I put a fan on them after I felt it. I had Memtest errors at those settings before the fan, then afterwards no errors. Hehe, the only fan I had was a Vantec Tornado, now my wife asks why the computer is so loud :)

[n0aH]

just picked up a set for 130 bucks...like them so far :) Only have them at 224 because my 17X stuck multilier is limiting me

Darn all you people ordering these things....now the price is up to $180 shipped!

on Newegg it keeps raising $5 every day!

Anyone know where to get them cheaper?

*sigh* was waiting until finals ended and I wasn't so busy to buy a pair, guess I blew it :bang head

[jivetrky]

Well I'm still gonna buy them even though they will cost $180...but I'm not going to like it!

[n0aH]

just picked these up for 130 bucks...love em :)

[jivetrky]

Where did you find them for $130?

[n0aH]

bought them from a guy on the forums..you can get them on new egg for 149 shipped at times..just e patient..they are 175 shipped right now i think

[squads]

mine came in the mail today....sweeeeeet can't wait to try it out

mine came in the mail today....sweeeeeet can't wait to try it out

nice, will do 280 like water, im waitng on my new cooler to go father then 2.8

[jivetrky]

well unless it drops by the time Newegg refunds my money from my Ballistix ram, I guess I'll have to pay full price :(

[jivetrky]

nice, will do 250 like water, im wiaitn gon my new cooler to go father then 2.8
Was 250 a typo? cause it SHOULD do 250 on air as that's the stock speed. :eh?:

Hello guys

This might be a silly question but here it is. Can I use A64 Tweaker on any other MoBo such as a NForce2/3/4 or even a Pentium board? Or what other program is there that would alow me to adjust as much timmings as A64 Tweaker allows?
I have 2GB G.Skills on a Abit AI7 that runs good up to 265 1:1 3-4-4-8
I am thinking I might be able to get more out of them, but need help with memory timmings.

Thank you

Daniel :beer:

[dominick32]

Well, I am back in business again. Seeing some other interesting posts throughout this thread and others I am going to try for 290 Mhz tonight and full stability. If you remember, I was able to boot XP 290 Mhz plus but with some stability. My goal is 290, Spi 32m stable.

Dom

[basiliskdragons]

Hi I brought a set of these to replace some value ram but I can't even get them to run at 250.I lowered my ht to 4x but it won't even get into windows at more than 230.Could it be the motherboard it's a neo2 platinum with the latest bios on it.
Cheers for any advice

[jivetrky]

Welp I finally got the credit back from RMA of Ballistix RAM....so I Ordered a set of these guys! I can't wait....hopefully will get it Thursday...then my rig won't be sitting there collecting a top full of dust! It will be running, collecting dust on the inside!

Dominick32: are you using active cooling to get that 280+ Mhz ? Just curious Thanks!

Dominick32: are you using active cooling to get that 280+ Mhz ? Just curious Thanks!

Jivetrky,
Immediately upon purchase of my ram it worked flawlessly at 280 mhz without any cooling whatsoever. The rig was even left on for 24 hours Priming with no problems. 280 mhz and 2.7 volts

To get 286 mhz it took a DS/DDS setting change, 2.76 volts and a simple 80mm fan "ghetto" affixed 1 inch above the sticks. I am still working at a 290 SPi 32m pass its just taking some time. :)

Dom

[seer33]

Well I think i might be ordering a set of these sticks..I need 275 mhz in a 5/6th divider to run with my opty @ 330x9 my mushkins fell shory about 10 mhz..and started having 3d errors so they got rma'ed. I hope I'm in luck with these!

[seer33]

how are u guys fixing a fan above the ram I'd like to know, I have a spare 80mm case fan and a spare 120 That i Wouldn;t mind puttin to use.

[dominick32]

Twist ties my friend. Just tie them up in any way or fashion possible. hehe :) Ghetto tie it.

Dom

[squads]

These sticks are great...I tested them stock and they worked great. Stepped it up to 275 at stock timings and no problems at all. I only needed 270 for the 180mHz divider so these are great. I might see if I can tighten the timings a tiny bit and still keep them stable. I saw far less stuttering in Oblivion with these sticks...now I need to go tryout FEAR with max texture resolution :D

[jivetrky]

ok....so I can't really say what my Opteron will do yet...but when I get this RAM I can test for sure. But speculating that I can hit 3006 Mhz (which is 334FSB) I could run a 5/6 divider or possibly even a 6/7 divider? of course that's assuming my CPU will do that and my RAM will perform similarly to yours, Dom.
And I kinda hope that my CPU will do better than 3.0 :drool: :)

I can start finding out Thursday or Friday! here's to hoping! *cross fingers*

[dominick32]

I have an interesting pointer to add to this thread.
I noticed that a user posted that Samsung UCCC has compatibility issues with Asus A8 motherboards and this could be the reason that some people are failing memtest at stock rated speed and timings with the Gskill.

Can anyone confirm this information? I was just browsing through a few other threads and found this.

I can confirm that I had stability problems on my A8N Premium @ 250mhz. What I did was increase the chipset volt to 1.6v and lower the Vdimm to 2.65v (I think) @ 3-4-4-8 1T.:beer:

These settings worked for me and I'm currently at 236x 11 with my crappy 3500+:bang head. I have yet to try 260X10 but I'll be back with results later maybe.

[redrumy3]

mine do 11 x 265 stock voltage and stock timings 3-4-4-8 and can do 10 x 280 stock as well, im working on hitting 3ghz, 11 x 275 might have to bump my cpu voltage up so im not sure

[dominick32]

Bump for recent questions.

[jivetrky]

I tested mine to 280Mhz @ 2.62 and they did fine....I didn't try any higher cause I only needed 278.
I'm sure they would do a little bit more tho, I basically found my CPU's max and what the closest divider would get me to and shot for that. So I didn't do the normal overclocking procedures...I just dialed in 280 and ram memtest for 2 full passes...

[sofarfrome]

how are the recent sets running? I heard that the later modules didn't clock so well.

[bboyfobulous]

i just got mine yesterday from the egg ... runnin @ 265 x 11

hopin to push to at least 275 and hopefully 285-290

[redrumy3]

i just got mine yesterday from the egg ... runnin @ 265 x 11

hopin to push to at least 275 and hopefully 285-290
im doing 265 x 11 as well, on stock voltages tried 275 and was having some problems have to play around more with my dfi board. weird i can do 280 x 10 but not 280 x 11 =/ still trying to work on 280 x 11

[bboyfobulous]

i just memtest'ed my 265 x 11 and i'm gettin like a thousand errors .... i can run it at 250MHz 3-4-4-8 1T with no problems... anything higher and memtest gives errors ....

at 265 i use 2.75v and still get errors.... i can guarantee that its not the CPU ..

did i get a bad set of sticks ????

Mine are basically the same way, I think it all depends on the manufacturing date on how good these O/C

i might try raising the chipset voltage .... did that help you pass memtest? ??

hopin it'll help me

[jivetrky]

I think that most peoples experiences with these is that raising the voltages does not help with OC's ...and in some cases can hurt it (as is some people actually got better results going a little below 2.6v)

You just have to keep playing to find your sweet spot (mine was 2.62v)

[bboyfobulous]

okae here's my status update

Opty 148 @ 265 x 11 and RAM @ 1:1 3-4-4-8 1T 2.5v
I Prime-tested my CPU & RAM for about 22 hrs w/ no problems whatsoever...
after that I ran Memtest and received errors at around 40% through the test (approx 60 errors)

okae so what I wanna know is ...
Is this okae to say my system is relatively stable??
or should I just use a divider and lower the FSB on the RAM back to stock speed?

[jivetrky]

well....those memory errors are gonna catch up with you eventually. And I dunno...maybe running the memory unstable can cause it to have more problems? sounds possible.

But I would say that unless you like blue screens and random reboots and stuff....you should probably lower it with a divider

[jivetrky]

You can always figure out what your max RAM is...and then see if maybe you can up your HTT and lower your multiplier (still giving you the same CPU speed) but giving you a higher HTT. Then the divider might come closer to your RAM's maximum.


Like if you goto a 290HTT and multiplier of 10 ...then you could do a 9/10 divier and your RAm would be at 261 ...maybe it'll do that just fine

[Mustanley]

Any errors in memtest indicate an unstable system in my opinion. Just because Prime95 did not error does not necessarily mean other programs won't. What prime tests did you use... small fft, large fft, blend? Small fft frequently won't cause memory errors because most of the data is held in the processor's cache.

Play with the voltage and secondary timings... those gskills ought to be able to handle 265MHz. Maybe some others can suggest which settings will affect stability on your combination of gskills and asus board.

[bboyfobulous]

in prime, the test I used was blend. i'm at work right now, but when i get back i'll try playing with the voltage more. i think that might the biggest problem right now.

hopefully these can handle 265 ...if not, then at least i know it'll run stock ...

[soulfly1448]

OMG, I'm buying some... Friday, when I get payed.

[dominick32]

Guys with the week 603's do not raise your voltage any higher than 2.7.
My sticks actually like 2.6 stock volts @ 282 mhz. The only time I needed 2.72 volts was OC'ing from 286 to 290 mhz. Samsung UCCC has a tendency to like lower voltages.

Cheers.
Dom

[Thoth]

Still running these... running them @ 275mhz @ stock timings/voltage... had problems tweaking the ram @ 275mhz.. but i had them @ some nice timings @ 265... (10x265)

when working on 275 tonight... i was working through the settings and got through most of them and then when i got to idle cycle timer everything went haywire... even when i rebooted the comp and put the setting back (to auto) the comp refused to boot... it was passing memtest... but bsod'ing as soon as windows loaded... o well...

[bboyfobulous]

i finally got these babies stable !! woo hoo!!

2.65v 3-4-4-8 1T

What did you set to get your divider at 9:10 on the A8N32? What value do you lower your memclock to, I tried setting it to 133 or 166 and just raising FSB, and it doesn't get high enough.

[bboyfobulous]

use above settings and use a 183 memclock limit

9 / 10 = .9
260 / 286 = .9

and i see you're runnin 0903 bios....i'm usin 1205

[CGR]

I have gotten mine stable at 275 with stock voltage. Have not been able to get them any higher. Even 1 mhz more and I get massive errors in memtest #8.

[Thoth]

i ALMOST had them stable @ 280 @ stock timings... lowered the "read preamble" and "max async latency" and the ram ran through 4-5 test 5's... but started generating errors on pass 6... (before someone asks... YES i do have a fan blowing over the ram... they are only *warm* to the touch)

would persue 280mhz more... but i have a lan party to go to tomorrow @ 9am... so tweaking will have to wait...

[darksparkz]

Mine isn't even Prime stable at 250, for a 1:1 ratio. How come many people get to 270 or higher? Maybe it's since I'm using an Opteron 175, the 11x multipler doesn't allow the ram to be clocked too high? Any ideas? I've tried loosening the timings, lowering and raising ddr voltages and everything. My previous OCZ Performance PC3200 could clock a bit higher then these G.Skills, while I thought the G.Skills were much better.

Thats very strange. Something in your configuration must be wrong. Can you post up a pic of A64Tweaker and CPUZ for me. If you are sure all configuration settings are correct, try changing your voltage to 2.6 volts because I see you have 2.7volts listed in your sig. If all else fails I would definitely consider RMA'ing these sticks because failing Prime @ 250 would mean the sticks are not considered quality and may have passed right through Gskills QC department.

Good luck.

[kbtat2]

When I first recieved my set from newegg they weren't stable even at 250 and I rma'ed them and the second set is great. Have you tried memtesting them? I tested my first set and they spit out errors like mad.
Maybe you could just get another set?

[darksparkz]

Here's my screenshot, CPU-Z says 1.250v for vcore, but my motherboard is set to do a 0.2v overvolt, so the actual vcore is 1.450v. vdimm is set to 2.6v now as well in BIOS.

I never did an RMA before, I ordered these from newegg. What would my RMA reason be? Defective/Failure? Since these were PC4000, and they weren't even stable at 250mhz. Do I just put the sticks back into the box and ship it back with their RMA number on it? They would ship me a new set for an exchange right?

Yes, definitely call up Newegg customer service and tell them that you ordered memory from them that is defective. They will issue you an RMA number over the phone and e-mail you with details on how to return. Newegg happens to have a very fast RMA program as well. Once they receive your sticks, there is usually a 3 to 5 day turn around.

Any sticks that do not run at the rated frequency/timings: 250 mhz (3-4-4-8) are to be considered defective/failing.

Good luck man!

[darksparkz]

Thanks a lot for the information! I'm hoping the new sticks would let me hit 260x11 with 1:1.

Also: RMA is 30 days from invoice right?

[Fangs404]

I have to post here. This ram is totally ridiculous. I'm running 250x10 1:1 right now 3-4-4-10 1T in my ASRock mobo at 2.7V. One of the reasons I picked this ram was because of how little voltage it requires. I made the right decision. I stuck the ram in, tuned to 250, memtested, and bam, I'm home free. I'd recommend this stuff to anyone.

A+++++++++++++++++++ WOULD BUY AGAIN

[Thoth]

I have some new findings... as i was able to successfully reproduce the conditions in my last full scr shot (ram @ 296mhz) ... and post a a64 tweaker shot of the settings... (which btw except for the "main 5" were auto set)

Cpu @ 9.5 x 250 , ram @ ddr466 (233mhz) dividor

http://webpages.charter.net/rbeitzel/ram%20at%20296mhz%20full%20shot.jpg

a thing or two i noticed about this that don't make a whole lotta sense...
1. this statement (from http://www.dfi-street.com/forum/showpost.php?p=203179&postcount=4 "Usually, this should be CAS latency + tRCD + 2 clock cycles. For example, if you set the CAS latency to 2 clock cycles and the tRCD to 3 clock cycles, the optimum tRAS value would be 7 clock cycles." ....so that would mean tcl (3) + trcd (4) + Delay (2) = 9 ... so how can this ram run BETTER at 8..
2. look at the "Max Async Latency" and "Read Preamble" .. stock settings for those are 7ns for "Max async Latency" and 5.5ns for "Read Preamble" everywhere i've read for those two settings... lower = faster... seeing that the motherboard automatically raised the "read preamble" didn't suprise me, but seeing that it LOWERED "Max Async Latency" by 1 did...

anyone else think this is just a tad weird...
also... correct me if i'm wrong... but even despite being a few hundred mhz slower than normal (cpu speed wise)... shouldn't 296mhz on the ram give me more bandwidth in sisoft (everest read lower #'s also but didnt put it in scr shot)

Comments/questions/suggestions welcome.

[Mustanley]

A few things...

First of all, on the DFI, dividers are computed using only whole multipliers. So when you are running a half multiplier (9.5 in your case) the board rounds up to the next whole number multi (10 in your case). Thus the actual frequency is not what you'd expect it to be, or even what is reported by cpu-z.

You actual memory frequency is more like 277MHz. 233/200=1.165 ratio.
So 250x9.5=2375MHz

2375(cpu freq)/10 (rounded up multi) = 237.5MHz x 1.165 (your ram ratio) = 277MHz

http://www.dfi-street.com/forum/showpost.php?p=203167&postcount=3

Next thing is that memory bandwidth is affected more by overall cpu speed than by memory speed on the A64 due to it's integrated memory controller. While increasing the memory bus speed does indeed help increase bandwidth, it still will not have as big of an impact as further overclocking the cpu.

For instance, leaving the FSB locked at 250MHz and changing the multi from 9 to 10 will have a huge impact on bandwidth.

Comments/questions/suggestions welcome.

I have a feeling it's because of the divider. The ram can finish with data faster than the CPU can get the data to the ram. I'm running 250x10 1:1, and my bandwidth is near 7000 (I need to rerun Sandra.....I forgot it exactly). My superpi is right around 34 or 35 also.

Im getting errors on Memtest v1.65 on test 8, theres massive errors on it like 80 errors. Im running it 264Mhz and timings and voltages on stock. The RAM is quite hot to the touch. Can anyone give any suggestions?

Thanks

[sofarfrome]

first off I would try some active cooling to see if the errors decrease...after that perhaps you can bump vdimm a little but typically these sticks do not like more V. what mobo do you have?

80 errors is nothing. I was testing my RAM at 290MHz yesterday and I got over 1,000,000 errors on test 6 in the first run :bday: Turns out I was only memtest stable up to 265, which works out fine for me.

[Rickster]

What batch of RAM do you have? I have 0606. OK maybe 80 errors isn't as massive as compared to yours

I have an Abit KN8, I like the board. (Don't tell me to change it to DFI)

When I get back I'll let you know about the Memtest retest on test 8 again with and without cooling and on stock frequencies and voltages.

[Rickster]

ok guys i did COLOR="Red"]test 8COLOR] last night

I'll call one stick A and the other B.

so i tested one stick at a time to see if it was actually the memory and these are results:

A in DIMM 1
pass 1: 0 errors (with fan)
pass 2: 0 errors (with fan)

A in DIMM 2
pass 1: 12 errors (with fan)
pass 2: 18 errors (with fan)

B in DIMM 1
pass 1: 0 errors (with fan)
pass 2: 0 errors (with fan)

B in DIMM 2
pass 1: 0 errors (with fan)
pass 2: 0 errors (with fan)


this concludes that both sticks are fine seen both can atleast pass the test in DIMM 1. but its real weird that A cannot pass DIMM 2, but B can pass DIMM 2 perfect. maybe the stick is just really chosey. computers are really weird.

so now i try A in DIMM 1 and B in DIMM 2 since A can pass DIMM 1 and B can pass in DIMM 2.

this is where the problems start again.

A in DIMM 1 & B in DIMM 2
pass 1: 2 error (with fan)
pass 2: 2 error (with fan, i tried R/W queue bypass counter at 16 in this pass)
pass 3: 1 error (with fan, i tried R/W queue bypass counter at 16 in this pass)

what is going on? i have no idea could another help me out? the fan seems to help out but there's still errors. howcome when i run 1 RAM at a time is works fine, but in dual channel it doesnt?

please help, thanks guys

I figured I would chime in here as well, seeing as how I have a pair of this ram. I have it set at 3-4-4-8, 1T, 2.6v in my bios, and can get it up to 255mhz only. 257 will cause me not to boot :(

I haven't tweaked them any further yet, especially since I do not understand most of the settings outside the "basic" ones (as above.) I may try using some of the settings from the screenshots in this thread though, and read up on it more.

Have you tried 2T? Often, when you start to get higher HTT speeds, you have to drop the command rate.

Actually yes (I forgot to mention it,) I tried 2T as well as 2.625v, and could not boot with either setting. I'm currently focusing on testing out my cpu's oc potential, however if I decide that I think I can push it further, I'm really going to have to try to push my RAM first, as I am already running it at 255mhz. Perhaps 2.65v would do it, or maybe I just have to relax some timings- that is, if relaxing the timings some won't defeat the purpose of gaining some extra mhz on the cpu.

you got to try both settings and benchmark both to get the better.

could you try setting your ram to 2.5Vdimm? ive set mine at 2.5Vdimm and it works better. dont know why. (maybe too much burning in:P). i just wanted to know if you can run it on 2.5 aswell
