lousy p4 overclock results?? p4c800e... read

[LuckMan212]

hey guys,

I have the following stuff:

P4C800E-DLX (v2) mobo BIOS 1014
P4 3.0C @ 3.5ghz (233fsb x 15)
Swiftech MCX4000 w/ Panaflo 92mm
Corsair XMS4000Pro 512MBx2
2x Raptors on ICH5R SATA RAID0
GFFX 5700 Ultra

I was fairly happy with this setup, getting decent scores in Sandra, 3Dmark, etc. But I really wanted to get the most out of my RAM and run it at least at DDR500 since that's what it's rated at. And the loose 3-4-4-8 timings of the Corsair are kinda crappy unless you really push it. As it is, 233fsb only gets me to DDR466 which aint so good.

BUT this machine is ROCK STEADY at 3.5ghz and is 100% prime95 stable for 24+ hrs, never gets over 47C at full load, idle @34c. I tried pushing the FSB to 240 so I could run at 3.6ghz but it's not stable in Prime95, but does boot and run winXP pretty well. So I backed off a little. whatever..

So I though I could do better with a lower multiplier and went a little crazy and bought a whole bunch of P4s from newegg and other places, and got:

(3) 2.4c's (some SL6Z3's and some not)
(1) 2.6c and
(2) 2.8c's (one SL6Z5 and one not)

I really was hoping to get a good 2.8 that I could run at 250fsb at least to get full potential out of my RAM. I have a lot of stuff hooked up to my rig and taking it apart so I could gain access to the cpu socket is not something I like to do too often because there are a lot of cables and everything is pretty tight. So I spent the better part of Friday and some of Saturday morning with the hood open, every time having to remove and reinstall the massive Swiftech heatsink (!!) without damaging everything. I used up almost my entire tube of Arctic Silver5 swapping all those CPUs.

bottom line?? WELL........ won't go into it too deep but suffice it to say, after so many hours of playing around in there and cleaning off heatsink goop, playing in BIOS, running Prime95 and pulling my hair out... I tested 8 different CPUs and wound up discovering that my ORIGINAL 3.0c was the best overclocker. I got the following:

2.4c SL6Z3s = maxed out at ~264fsb = ~3150mhz
2.6c would NOT even boot once I tried o/c'ing it... it's getting RMAd
2.8c's, both maxed between 225-237fsb = ~3300mhz

so none of these were very good overclockers, including the famous SL6Zx versions that people were all hyped up about for awhile for being P4 "EE" cache bins... even the 2.4c ~264fsb which was my HIGHEST fsb overclock was only getting ~5650 in sandra memory bandwidth which is only about 200 more than my 3.5@233 was getting. not worth the significant MHz drop. phooey.

are these results really bad? am I just unlucky? :confused: I see on these board peeps getting real nice fsb overclocks 275fsb+ some people even getting 290fsb++ which is really sweet. I realize that you must go 5:4 on the ram but I even tried that and it wasn't happening... guess I just got some crap CPUs.

any other advice or wisdom?? :eek:

I doubt they were all "crap".


Ever consider "limited practical application" as part of the problem? I seriously doubt you saw the maximim oc of any of those cpu's in "hours of testing". Even with a week of testing you would have a hard time hitting the maximum oc on half those cpu's much less all of them. I'd be willing to bet I could get 3.4 from one of the three 2.4's if not two of the three. You can't oc a rig in a day, I'm not sure Macci, Opp, fugger or any of the heavy hitters get the max. oc in a few hours.

ok, but what exactly do you mean that I did not do enough testing? are you talking about "burn-in" or what? also I did do a fair bit of testing on each CPU. I spent at least 2 hours on each one, toying with various FSBs, voltages, and mem ratios... most all testing was done at 1.675v but I did push up to 1.75vcore on occasion. I am open to suggestions but I'm just not sure what I missed in my testing......

of course I am using air-cooling but I do have one of the beefiest HSF combo's money can buy. I am not really into water (yet) but I hear stories of people getting great air-cooled 2.4s up over 3.5ghz pretty easy. :D

[Detract]

Maybe you should try some 3200 or 3500 BH5 Ram. Give it some extra voltage and it should run ddr460 with tight timings easily. Even though your RAM isn' maxing out, I found that switching made a significant difference in my case.

[LuckMan212]

where do I get BH5 ram? and you are talking DDR460 in 5:4 right?? cus I'm already running ddr466 @1:1 with my current ram but at 3-4-4-8 ... don't want to 'downgrade' :D hehe

edit: I was checking out these OCZ PC4200 EL series (click here) (http://www.ocztechnology.com/products/memory/OCZ+EL+DDR+PC-4200+Dual+Channel) they're lookin pretty sweeet!! but they are expensive like $450++ at least from what I can tell, and hard to find too.

guess they can go on my 'wish list' :p -- anyone else got any experience with these new OCZ sticks??

[Grandpa Dan]

I don't know where to start. My system will run stable with a fsb over 300 at 1.6 vcore. It won't even post at 1.625 vcore. I tried Hyper-x PC3200(2x256) and PC3500(2x512) and a fsb of 260 is the highest I could go regardless of dividers, voltages, timings anything. Now look at my sig...Same exact system except with Mushkin. The process to get a system to boot up, make needed adjustments, reboot, memtest, and then stress test and benchmark takes a certain amount of time. I know with my rig if I change too many bios settings at one time it freaks out and won't boot up on the first try. These things are just off the top of my head, I know there is plenty I've left out. I'm sure some of the guys here will be happy to fill in the spots I left blank.

GD

P.S. I'm running DDR 466 at 5:4, 2-3-2-5.:eek:

[LuckMan212]

you think the Mushkin is better than the OCZ or the Corsair? also, do you overvolt your northbridge at all? got any cooling on the NB? just curious. sometimes I wonder when going >250fsb if it ain't just my NB giving out. things got real sketchy >266fsb with my 2.4's (SL6Z3's) even though temps were in the mid-30's and everything else seemed OK. random reboots & such. I didn't see that with the other chips (never got over 240fsb with anything except a 2.4).... just got errors in Prime95,etc is what makes me think it could have been the NB.

P.S.- sweet OC you got going there;) .... I'm jealous of that FSB what are your sandra scores? 50% overclock on a northwood .... reminds me of the good old celeron 300A's !!!!

[batboy]

I have Corsair PC4000 Pro, OCZ PC3500 EL, and Kingston HyperX PC3000. The PC4000 does pretty good using the 1:1 ratio. I have a 2.8C running at 250 FSB using the 1:1 ratio. I've gotten 2.58 gig out of it although it wasn't Prime stable at that speed. But, that same PC4000 RAM totally sucks when I tried using it with my 2.4C at high FSB and with the 5:4 ratio.

My PC3500 stops at 275 FSB using the 5:4 ratio and won't go higher even using the 3:2 ratio. My lowly PC3000 with BH-5 chips is the best performer with my 2.4C. It'll do 283 FSB using the 5:4 ratio and tight timings, plus I've gotten it up to a max 308 FSB using the 3:2 ratio (not stable... see signature for Prime speed). My point? RAM makes a big difference and some RAM just don't play well with certain combinations of components and settings.

so how can I find out where to get some sticks with BH5?? I have some PC3200-LL Corsair sticks in my other rig... might those work? I will definitely be buying some new sticks it seems... :( the ol' wife ain't gonna like that............:D :D

[Detract]

Ive had the same luck as batboy in regards of RAM. Kingston KHX3200K2/512 is BH5, the same as Mushkin Black Level II 3200-3500 RAM and platinum versions of OCZ 3200 - 3500 as far as I know.

You managed to get 7 CPU's past her, Im sure you can manage a couple sticks or RAM :D .

[batboy]

Yeah, at high FSB, N/B cooling starts becoming important. Here is a link about my cooling mod.

Here is Sandra benchy at 300 FSB:

[batboy]

Supplies of RAM using the BH-5 chips are running out fast. If you look at newegg.com, the KHX PC3000 and the "non A" KHX PC3200 RAM has a good chance of using BH-5 if it's rated 2,2,2,6 timings.

Mushkin PC3500 Black level 2 has BH-5 chips (perhaps the PC3200 Black level 2 too, but I'm not sure). A while ago, the OCZ PC3500 Platinium Edition had BH-5 chips. Not sure if they still do or not.

Your Corsair PC3200 probably ain't, unless you've had them for a while. I'd try them anyway just in case since you have them handy.

[pkrew]

Wow, I wish I had the money to buy all of those cpus. While its possible that you just got unlucky with all of them, its not likely. I've had two 2.8Cs. One a Costa Rica did 3.4 and a Malay that does 3.6 at 5/4. I run it at 3.45 using 1/1 and the timmings in my sig becuase its faster that way. I sold the Costa Rica and picked up a 2.4 MO just for fun and it ran out of the box at 288. I'm hoping to do a little better with better NB cooling. The advise that Batboy et al have given you is right on the money. Try out your Corsair pc3200 and if its not bh-5 then I'd buy some that is. Once you have the ram then get back on here and post how you're doing. I would be supprised that with the input of people like Batboy and Grandpa Dan you wouldn't get a couple of your cpus running very nicely.

[LuckMan212]

ok thanks for all the tips guys.. I'm gonna check out my old twinX corsairs 3200LLs (they are old so maybe they're BH5) and if not, I'll sniff out some new sticks.... I'll check back in w/ the results...

also thanks for the tips on the NB cooling.. the Swifty looks NICE but I am worried about those clips poppin' off, so I will probably go with something simpler-- any other specific recommendations? That italian one looks decent but I have no idea who is distributing it in the USA....

[LuckMan212]

guys please I need a little more help... I am trying to get a good overclock going but I am at a loss when It comes to the RAM.

it seems there are no more BH5 chips out there and the chips I have (corsair CMX512-4000PRO's) are from what I can tell, pretty decent chips, or they are supposed to be.....

i see there are now PC4400s from corsair and I also looked at the OCZ PC3700EL Rev2's which claim to run 2.5-3-3-7 which is better than my 3-4-4-8 corsair's but I wonder if they will help me OC better? currently Im running DDR466, 1:1 at 3-4-4-8. no problems but I have pretty low UNbuffered Sandra scores:

http://f2systems.com/files/snap059.png

can anyone recommend some real specific modules that are good for OC'ing on i875 chipsets?

also please post your sandra UNBUFFERED scores for comparison.
thanks!!:)

thanks for the tip!!
just ordered 2x512mb's..................:D

[LuckMan212]

well I said I'd post back after making some changes to my rig... so here I am, back to post my latest findings!:D

I ditched the Corsair CMX-512-4000 sticks I had and found some Mushkin BH-5 PC3500 level2 chips (2x512) and snagged em. Ran all my CPUs through the usual battery of tests, this time with tighter timings and at 5:4 instead of 1:1. As most of you all suspected, the BH5 ram was a much better "fit" with the high-fsb SL6Zx's, especially the 2.4's. In particular, I settled on a 2.4C that was 100% PRIME stable at 279fsb, 5:4@2-3-2-6, 2.85vdimm, 1.675vcore. CPU is nice and cool at 33C idle, 46C at full load (2 instances of Prime)

The other 2.4's topped out all in that range, 275-280fsb, so I don't know if I am bumping up to the limits of the Air-cooling (I am using a Swifty MCX4000 with a 92mm Panaflo-- pretty hefty as far as air goes, so it's decent!! :D ) or if my Northbridge is giving up at those fsb's, or maybe the RAM. at 5:4@279=446MHz on the Ram which is only rated to 433 so that's not too shabby IMHO!! I was gonna try a northbridge cooling mod but after looking at it I realized I might not gain too much since I would have to use adhesive vs. the clips (my Asus mobo has no holes) which might have just been about the same, and a lot of extra hassle to put all that stuff in)...

So, here's my new benchies, for enjoyment. I am happy for now .... until Tejas comes out! hehe :beer:

P.S.--- Grandpa Dan, you mentioned that your system "wont even post at 1.625vcore" but is totally stable @1.60

hmm... was that a typo or are you saying that more voltage is sometimes detrimental to an O/C? (I know >1.7v is dangerous on Northwood's!!)

I am currently very stable @1.675v, low temps, etc. At full load with 2 instances of Prime running, my voltage as reported by MBM drops to 1.55v which is about as low as I think it should get :eek: But now you make me wonder if I wouldn't get a better OC with lower voltage?? or, please clarify. thanks!

[Detract]

Each CPU will have its own sweetspot in regards of vCore. Some like a lot of voltage while others get no added performance with extra voltage. You should always try and get the most out of chip @ default vCore before increasing it. Personally on air I wouldn't go over 1.7v, of course some will argue that this will decrease the life of a chip, however by the time it dies you'd of probably upgrading anyway.

[LuckMan212]

I see what you mean... but am I right in my thinking that at full load, your vcore shouldn't dip below 1.50v ?

[Detract]

Dont know why its doing that, but if its stable its fine.

[LuckMan212]

well I did some more testing and found that this new 2.4C is stable at 1.625vcore so I backed it off to that. That puts me exactly at 1.50vcore under full load which is perfect. Runs for 12+ hrs prime stable. Temps went down 1C as well... bonus:D

[skane]

Your 2.4C 'Z3s can probably do more with good air or average water cooling. Try using a 3:2 ratio and find the top end of the CPU @ the vcore you plan to use 24x7. Then vdimm-mod the board to *make* the Mushkins run at that top CPU/FSB speed using 5:4 ratio and tight timings.

[LuckMan212]

is there a good site that shows how to do the vdimm mod on a P4C800-E?

Correct...more is not always better. I back the voltage off until I get errors than bump it up a notch. Try 2-3-2-5 on your timings. It usually runs as well as 2-3-2-6.

thanks Dan... I'll give it a try. Also, I'm curious, what was the highest FSB you were able to squeeze out (stable) on Air cooling? or did you go straight to H2O?

also, same question for the VDIMM MOD.. before and after.

reason is, I'm considering one of these mods (or both!) and want to know if it helped you a lot/a little/etc

thanks again for all your help, btw.:p

[Grandpa Dan]

Always been on water. The mod didn't give any more fsb. It allowed me to keep tight timings at a high fsb with a 5:4. It sorta gave a higher fsb(overall). but I can run over 300 with a 3:2 instead of 285 fsb 5:4, 2-3-2-5 before the mod. 294 fsb 5:4, 2-3-2-5 with the mod.

That Mushkin likes the volts. I giving mine 3.2v. 24/7

thanks again for all your help, btw.

You're welcome...btw;)

Here are 3 links to the same vdimm mod for the P4C800E. The IC legs have enough spacing to use small grabbers if you don't want to solder. Most folks use a 50K VR. I also use a 50K on my rig, but it's somewhat overkill for this mod; I have the VR set to 15 - 20 K to get around .28v increase over the BIOS setting.

:D Nice thread and some interesting testing - glad I came across it!
Grandpa Dan - your findings with the P4C/2.4C combo are intriguing!
After my 2.4C ES degraded a bit and would only hit 3.0/250FSB Prime Stable (very old chip, first of P4C), I got rid of it and "upgraded" to a retail D1 3.0C.
I had the vDIMM mod on my P4C and even with that whatever I did I could not get over 285FSB, even with an 8x multi, unless I dropped a stick of RAM to run single channel. I certainly could not get the CPU over 3.2 either on air. I thought it was a limitation of my board rather than my RAM for some reason. Possibly I needed to try some other RAM first!
Now my 3.0C does 3.5 at 233FSB and DDR466 CL2.5-4-8-8 at 2.8v on the same Twinmos 3200 so its a bit faster overall but still not fast enough especially memory scores. Maybe I will put the vDIMM mod back on to see if I can tighten timings but the high multi of the P4 3.0C is really killing memory.
Thoughts now are on an M0 2.4C or 2.6C, or a 2.8 Prescott.....I'll wait and see how the initial steppings go first.

[LuckMan212]

didnt do my volt mod yet... a bit nervous about it. what I did try was lower my FSB:MEM to 3:2, and I was able to push my fsb up over 300 no problem, prime was stable and temps <35C so no sweat there.

guess I got a good chip here... just need to get the RAM situation sorted...

I was thinking of ditching the volt mod and just trying out some Buffalo, GEIL or OCZ pc4400 sticks... what do you think of that.. I know they dont run 2-2-2-5 or anything but bandwidth should still be pretty decent at 292fsb 5:4.

whadya think

[Grandpa Dan]

whadya think


I thought none of those 2.4's would go over about 265 fsb?...lol... I think that 292, 5:4, 2-2-2-5 looks about like this:

i wonder if my Mushie's are up to the challenge as well.... hmmm!! ;)

maybe I will try that volt mod after all... hmmmmmmm

[Grandpa Dan]

Yeah, the volt mod gives a nice little bump in the bandwidth dept. The mod can be done in about a 1/2 hour with no soldering.

whadya think

if you can try to pick up some buffalo tech PC3700 with Bh-5 chips, the reason why your other PC4000 sticks didn't overclock as good as the Bh-5 chips is because intel chipsets (865PE/875P) have issues with CH-5 Chips and high FSB with the Dividers. this is why your seeing a increase in overclock because of your ram being Bh-5 intead of CH-5 chips, and almost all PC3700 and high are made with CH-5 CHips,

of coase this intel chipset and High FSB+dividers having issues is all a theroy i have, but your guys experiences, and others in other forums have pointed to this theory being true. i myself will test this theory, i gotten my 2.8C processor at 3.4ghz max on my OCZ PC3700 rev2 sticks, and i have my muskin Black level 2 PC3500 sticks comming in mon-tues, so i'll see if i can overclock higher with those sticks compaired to my OCZ sticks

[LuckMan212]

well I decided to be brave and attack my $200 mobo with a soldering iron.... I did the VDIMM mod and it took about 45 mins. thanks to everyone who posted tips + pics...

I used a 47k pot and used a meter to test the voltages. I have mine set for a +.3v mod, so 2.85=3.15. I verified this by reading the voltage at the VR location on the board.

OK... so now the fun part... the testing+benching. Well here's where it gets fishy. I booted into BIOS and set my timings to 2-3-2-5, PAT enabled, 292fsb, 5:4 and this is how my Sandra bench looks... It sucks:
http://f2systems.com/files/snap106.png
http://f2systems.com/files/snap108.pnghttp://f2systems.com/files/snap109.png
so what could be wrong??? PCI latency? DRAM idle/refresh time? I am at a loss. My bench didn't really budge more than 20 pts over my 279fsb 2-3-2-6 bench from before!!! and that's with another 150mhz AND tighter timings... so something is "UP" anyone got any advice??? I am a little bummed out now!! I even tried with 2-2-2-5 timings, and score only went up about 20pts and was very unstable... so that's not it.

It seems like Grandpa Dan and others score 6300-6500 which is a good 700pts higher than me, and apparently with the same settings!:mad:

Did you run a clean memtest86 at this setting? Memory errors can lower scores without crashing the bench. What version of Sandra is that? Bench scores can vary between different versions of SSS too.

[LuckMan212]

yeah Skane you might be right! :eek:
I ran memtest86+ and at 292fsb I am getting errors. So my new top end is 283fsb. There I can run stable, no errors in Prime or memtest.

Sandra score went up about 100 pts or so, now I am at ~5850 or so. A little better but still FAR AWAY from 6300+ where I see a lot of 292fsb'ers at. I am getting some OCZ PC3700 EL GOLD on Tuesday so hopefully that will let me run 292 or higher....

I figure if a 4MHz increase in FSB translates to roughly 100 Sandra points, then another 9MHz (283->292) should give me about 225 more points hopefully, which would place me around 6075 or 6100 in Sandra. Not breaking any records, but anything over 6K+ will make me happy.

Until then, I've updated my Sig with the latest. :D

also- I'm using Sandra v2004.10.9.89 -- is that what everyone else is using??

[LuckMan212]

also, a question. are most peeps with 6K+ sandra scores doing it on i865 or i875? reason I ask is b/c of PAT vs. MAM, etc... seems Grandpa Dan has a P4P800 which is i865, vs. my i875 P4C800-E Dlx.

Just wondering if this could be the reason for the discrepancy.

[Grandpa Dan]

This will probably only cloud the issue further, but I checked and with a fsb of 290, 5:4 @ 2-3-2-5 my sandra score is 6200+. Download ctiaw(I don't have a link...google) it gives a more accurate memory bandwidth assesment. with my settings as shown above ctiaw reads just under 6500.

GD

BTW, What did you do with the other m0's? PM me.

[BBThumper]

......did you ever look at Memtest Granpa Dan? It usually gives a little lower than SiSandra unbuffered test so I think its closer to the truth......

[LuckMan212]

here's my results... interesting:

ctiaw: Memory Read Bandwidth : ca. 5992.1 MBytes/s

pretty much in line with my sandra results (about 200 pts higher, but then Grandpa's is also about 200pts higher than his Sandra...
...so that still leaves me 500pts behind him!!:mad: )...

but I believe more and more that it's due to subtle differences in the memory timings of the i865 P4P800 vs. the i875 P4C800, not to mention I am only at 283fsb vs his 292. I am waiting for my OCZ pc3700 gold which is coming on wednesday... then we'll see if I can tighten this thing up!:D

I had to up my VCORE to 1.675 to maintain stability in Prime. so far I am 100% prime stable for 14hrs.. going to shoot for 24-36hrs to be sure.

I have the XMS4000 pro also and I run it at 2.5-3-4-6 and it's stable at 235MHz fsb. At higher speed, I drop it to 2.5-4-4-7 and it's stable. But at super high speed, the 3-4-4-8 is recommended.

Which memtest? Yeah, I've run sandrs unbuffered...don't recall the score or setting. All anybody asks for is usually the reg. sandra scores.:rolleyes:
