There is a sticky dedicated to C2D overclocking results. Why did you make this thread? Do we really need a thread for all models?

GrossmeisterB

I think it's easier having one thread for one CPU, as it is a lot easier for searching results of a certain CPU...

My E 6400 is at 3400MHz (8x425) so far, on my P5WDH, vMCH = 1.6Volt, vCORE = 1.43Volt (CPU-Z), all other settings on "Auto"...so, it's just the beginning, it is rock solid at that speed, I will try higher frequencies now... :)

Over 3.84 GHz Win XP can't boot because the less voltage on MCH. After that I've modded with a 10 VR and I have burned the mobo :(

Tomorrow I'will post the cpu-z screen and more details.

I'm starting to notice something here... all the best overclocks are being done on asus boards. I'm wondering if it's actually the chip at all, or if it's the board not wanting to go higher.

I have to remove my motherboard everytime I want to do that so it's a bit tedious. I did disable the Qfan settings and the fan is spinning @ max and knocked it down to about 62 load so not bad but still a little high for my liking. Using a Lian Li V1000 II Plus so there's no real fan blowing over the motherboard, just the CPU fan blowing air out the 120mm exhaust and I have a 120mm exhaust near the motherboard, and an intake in the front but it's in front of the hard drives.

Weird, I'm using Coretemp to monitor temps and I have it at 3.2ghz and it's reporting load temps in the 58-60c range but when I stop Ortho is drops down to 40ish and AIBooster/PC probe report load temps @ 43-44c, on stock volts. I touched the heatsink too and its not warm at all. Also shows 30-32c in BIOS whenever I boot up.

Wow I can't believe all of you guys are running 3.2ghz+ 400fsb+ using default VCORE!!! I need to pump my vcore up to 1.4125v to get my ds3 to post at 400fsb.

I wonder what causes some e6400/ds3 combos to be able to be stable at stock vcore with 400fsb???

after flashing the bios of my DS3 I am now prime stable at 3.2 GHZ with STOCK volts, instead of needing 1.43 volts. It was not the chip at all, it was the bios. I will update with new clock speeds when I get em.

Do me a favor and check what CPU-Z reports your voltage at under load, could you? I'm trying to get to the bottom of this possible overvolting at stock deal.

After 6 hours of testing last night after switching to F4 bios on the DS3 I have come to the conclusion that if you leave your VCORE set to "NORMAL" in the bios it will AUTOMATICALLY INCREASE VCORE to accomodate your OC. That is why you see people saying," OMGZORZZZZ I just flashed to F4 and I am OCed to 400x8 with DEFAULT VCORE!!!" Check CPUZ. I garauntee it will show between 1.39-1.45 and not 1.325.

On one hand it is nice that the board will automatically set the voltage to stabalize your OC however on the other hand this is not very accurate and every time you boot your PC it will fluctuate a bit. NEVER USE AUTO. I garauntee those people claiming to OC at default vcore will not even post if they set the VCORE from "normal" to manual 1.325.
geee man you were the one that started the hype and we jumped in to tell you what was actually happening with your system and all of a sudden you've come to a conclusion rofl..............next time just read your own overhyped thread and you'll get the answer much quicker ...............wonder what you tested that took you a long 6 hours to realise that something's strange about the new bios lowering the vcore for 3.2Ghz OC by a wopping 0.1V+: :exclaim: :exclaim: :exclaim:

I don't think you can make a general statement like that. No offense but I'm running 400x8 at default voltage. I haven't flashed to F4 yet. I'm still on F3, but CPUZ shows default voltage, even after 15 hours of dual prime.
http://www.cluboverclocker.com/images/stang/prime_stable.gif I just decided to link to it in case it was too big. Here is another one with dual prime running, CPUZ and EasyTune 5. I don't know what else I can use to tell if the voltage is accurate. http://www.cluboverclocker.com/images/stang/defaultvoltage.gif
Core Temp reports the temperatures at 34C and 32C at full load it barely breaks 40C

How do you guys get CPU-Z to show the correct voltage? Mine shows the same no matter what I do :( I have to use Asus PC Probe II to get a voltage readout.

By the way, what exactly is the default voltage for Core 2 Duos? I've seen .85v all the way up to 1.35v on Intel's site.

08-18-2006, 12:23 AM

My CPU is nice,too!!

I'm at 8x438MHz right now, week25 CPU on Asus P5W DH BIOS 1101, vMCH = 1.65V, vCore = 1.45V in Windows/PC Probe II (set to like 1.4625 in BIOS), memory runs with a divider at 657MHz CL4-4-4-16, too bad it won't do 1:1...

It is prime stable, but I only had it running for 1.5hours, I had do cancel it because I wanted to game... :-P

I will try it longer later on...

And I wanna do vMCH mod on my board and get some watercooling to it... ;-)

Vmch an other voltages if set to Normal also increase (vmch Normal = +0.3V) if you overclock. And don't trust cpuz, just use DMM :)

That's related to the DS3 posts, right?!?!

CPU-Z sucks, hehe...I saw one guy on eBay germany selling his C2D, claiming it would do 3400MHz on 1.213Volts, then I told him, that it's a CPU-Z bug, and he should show me the DMM measuring...lol...suddenly the auction was ended.. :P

stang

08-18-2006, 12:34 AM

It's hard to get a "screenshot" of a DMM and prove you are actually running at 400x8 while you are measuring. I guess it would have to be an integrity issue. GAM DMM= Digital MultiMeter.
F1 through F3 I have left everything in the BIOS set to normal or auto and just adjusted the FSB to 400MHz.

stang

08-18-2006, 12:43 AM

I just rebooted and manually set my voltage to 1.325v The computer still runs fine at 400 x 8 and CPUZ's voltage went from reporting 1.296v to 1.312v. I think I'll set it back to normal. LOL If CPUZ is right, manually setting it to 1.325v actually increased the voltage from what I was running before. :) Easytune 5 still reports 1.31v.

Just flashed to F4 and temps spiked on idle like 6C. CPU-Z was showing 1.4 instead of 1.3. I also found it would happen with the RAM too. It spiked to 2.1 and there's no way of setting 1.8 AFAIK, so it's at 1.9. The only one I didn't move was the PCIe, but now I'm wondering if that's getting overvolted too!?!? Anyway to check that guys?

is that orthos stable ???

i thought week 27 were good like week 25 and week 26 :(

Thats 100% stable via orthos. Ran for 20 odd hours. It might go further but not had a chance and to be honest a 3.28 doesn't seem to shoddy for air cooled??

I am glad I am not the only one who has needed 1.5v+ to get this E6400 stable at 3.3+GHz.

Right now I am priming at 3.4Ghz (486X7) at vcore 1.5875v so I hope this does it finally!

I fold 24/7 on both Core with this machine. I have never had a failed WU due to stability issues. I often play BF2 while folding as well with no issues. I don't run stability programs like Prime95 because I would rather be spending the CPU time folding. Although folding may not be quite as harsh on the CPU as Prime95, it is very demanding.

The limiting factor on my overclock is not the CPU or the Vcore. It is the memory. The NB will do 448Mhz, but my memory will only do 430Mhz. I am instistant on keeping this computer 1:1, so until I get new memory and do the NB Vmod, I am stuck here.

How many of these overclocks at 3.4,3.5,3.6Ghz are 24 hour stable on Orthos?

I can get to 3.5Ghz on my 6400, but its only 4 hour stable on Orthos, but every else seems perfectly stable on what I do? I can do single 32MB SuperPi also, but not dual. Is there any special assigning of cores to each SuperPi instance?

To tell you the truth, as long as my system is stable for what I need it for, why bother. Sure you can say my system isn't truely stable (I am not saying it won't pass the 24 hours Orthos, I just don't know, never ran it). But I fold 24/7 on both cores and have never had an issue. That is stable as far as I am concerned. Anything more is just unecessary.

My computer can do all the things I need it to do, and has never crashed or rebooted randomly. Ran SuperPi 32MB fine, yet because it didn't pass 24 hour Orthos I was concerned and started to take my overclock down.

But I am contemplating whether to put it back to 3.5GHz and just run it there.

Seem to have trouble keeping it stable at 3.4, 3d mark keeps hanging.

What voltages are you using (gMCH, FSB , memory & timings/ratio etc)?

I have it at 3.2 now, seems to need around 1.4 to keep it stable though

Just like you said, run your computer at whatever speed meets your daily needs. Orthos/prime is just an easy and standarized way of comparing the stability of your system to that of anothers.

That's why bother I guess... :)

Hmm, damn DS3 is giving me problems.

I flashed to F5, but for some reason it didnt seem to work. Still showing F3 in everything.

Also, even though it will run for hours, benchmark etc. I restarted it, and now black screen. Time to reset CMOS again, which means removing the damn video card because the CMOS reset is in such an awkward position.....

BTW, I dont know if this has already been answered, but when changing the ddr voltage on the DS3, does it add whatever amount (i.e. +0.4) to 1.8volts?

So if I put +0.2, my ram should be at 2.0volts?

:fact:
After 6 hours of testing last night after switching to F4 bios on the DS3 I have come to the conclusion that if you leave your VCORE set to "NORMAL" in the bios it will AUTOMATICALLY INCREASE VCORE to accomodate your OC. That is why you see people saying," OMGZORZZZZ I just flashed to F4 and I am OCed to 400x8 with DEFAULT VCORE!!!" Check CPUZ. I garauntee it will show between 1.39-1.45 and not 1.325.

On one hand it is nice that the board will automatically set the voltage to stabalize your OC however on the other hand this is not very accurate and every time you boot your PC it will fluctuate a bit. NEVER USE AUTO. I garauntee those people claiming to OC at default vcore will not even post if they set the VCORE from "normal" to manual 1.325.
I do not think so.My system would boot with NORMAL at BIOS.After I have selecte 1,475v,it actualy boots immediately and is completely stable:woot: :fact:

I'm making progress. Best thing was the cooling on the NB

http://i13.photobucket.com/albums/a294/DublinGunner/Benchmarks/3.jpg
One thing I have noted though. The NB heatsink is totally inadequate. I tied a 60mm fan on it, and it now stays cold to the touch, and I've had no re-boots or stability problems since. (I had to 'ghetto' the lead into a 4 pin molex though, have it @12v, gonna change it to 5v should be plenty to keep it cool)

Yeah, I've got a Ninja sitting here waiting to be lapped. But I don't have the padding anymore. I tried using the padding on the bottom of a mobo box, but that sunk over time and then the bolts came loose slightly. I noticed temps rising gradually and finally put 2 and 2 together. So I wonder if Scythe could send me a pad for some $$. That or I'm gonna cave and Tuniq it up. :D

Not even then. Some people are reporting lower temps, but I've tried everything short of actually lapping my E6400 and still get the same temps. Stock cooler, an Xp90, or an Ultra-120 all read 70~ when running Orthos. I've reapplied, readjusted, prayed, and everything else I could think of. At one point you just either accept that Coretemp is wrong, or your IHS is screwed. I went with Coretemp being wrong :p

It's not like my heatsink doesn't get warm; it does heat up pretty well.

I prefer run Orthos using Blend test (CPU & RAM) or Small FFts ( stress CPU) cause large FFTs test just stress RAM .

Large FFT's doesnt just stress ram, it stresses the CPU also. Its just with the size of the FFT's, it cannot all fit in cache, so system ram is also used extensively.

Small FFT's do ONLY stress CPU.

i believe large fft is more accurate then blend test.. last time during my AMD rig, blend test nvr gave error, but one day i tried large fft, it failed right after 10mins..

hehehe so show us some Orthos prime stable and vcore measurements. heheheh if you are only able to boot at that and do 1M or similar....................than you're 200Mhz short of the last CPU i've tested heheheh :p:

So if my week 28 E6400 runs 3.2-3.3Ghz at only 1.32v .. I should keep it?

Im thinking of buying a E6600, but I dont know if it worth it. I dont bench much theese days, so as long as my games run smooth im kinda happy.

Either my P5B or my XMS 5400C4 keeps me from running any higher FSB, so I dont know how far it will go.

With 3.3 @ 1.32v ... 3.5-3.6 on 1.4-1.45v maybe?

So if my week 28 E6400 runs 3.2-3.3Ghz at only 1.32v .. I should keep it?

so decide - 3.2 or 3.3 GHz. But in both cases my answer is YES!

Im thinking of buying a E6600, but I dont know if it worth it. I dont bench much theese days, so as long as my games run smooth im kinda happy.

in games the difference between E6400 and E6600 is almost none. If your E6400 overclocks well, then a 3.2 GHZ E6400 will be even better than an X6800.

Either my P5B or my XMS 5400C4 keeps me from running any higher FSB, so I dont know how far it will go.

XMS5400 is not a problem, 'cause it should do DDR900 without problems.

With 3.3 @ 1.32v ... 3.5-3.6 on 1.4-1.45v maybe?
you need 0.1V more to get about 180 MHz.

Lapping

Iâ€™ve finally got my E6400 running at a reasonable temperature. Using Orthos/dual Prime it had been reaching 70 deg C (T Junction) even at 400 MHz FSB, so I decided to take another look at the heat spreader. As you can see in Photo 1 it was clearly raised at the edges. See also that it has scratched the base of the heat sink where it was clamping at the edges only.

Photo 1
http://members.iinet.net.au/~gbyers/cpulap.jpg

After a bit of wet and dry at 360, 600, 800 and 1200 grit I reached a point where the centre of the IHS was bared to copper so the heat sink would make close contact directly above the core. I didnâ€™t want to keep sanding until all the nickel was gone without testing the effect of this first.

With everything reassembled and dual instances of Prime running for over two hours (400 FSB) I now had a CPU temperature of 62 deg C, a benefit of 8 degrees C! â€“ and thatâ€™s before the 200 hour bed in of the AS5 thermal grease. (Ambient was 23.5). I didnâ€™t believe it before, but you have to try it if you think your temperatures are limiting you.

North Bridge Strap

See this thread
http://www.bleedinedge.com/forum/showthread.php?t=23803

Iâ€™ve done some benchmarking with Driver Heaven Photoshop Benchmark v2 and SiSoft Sandra 2007 to test out this issue of the chipset strap setting. It can be clearly seen that 400 FSB is superior to 401 FSB and almost as fast in day to day tasks as using 425 FSB. However there is the option of setting BIOS to 400 for booting and then using ClockGen to raise the FSB to 425 from within Windows at start-up. This option produces superior benchmarks but requires a substantial FSB and NB voltage boost. See table below.

FSB--------------------------Driver Heaven--â€”SiSoft Sandra Mem BW
Boot 400 FSB------------------105.0 s------------7272 MB/s
Boot 401 FSB------------------116.0 s------------6700 MB/s
Boot 425 FSB------------------101.1 s------------7200 MB/s
Boot 400 ClockGen 425 ------98.5 s-------------7318 MB/s

Based on the results here it is apparent that this board produces great results at 400 FSB with minimal voltage increases over default required. The voltages required at each of these settings are as follows:

FSB---------------------------CPU V BIOS--Mem V--FSB Term V--NB V
Boot 400 FSB------------------1.3875------1.90--------Auto-------Auto
Boot 401 FSB------------------Ditto
Boot 425 FSB------------------1.5125------2.00-------1.400------1.45
Boot 400 ClockGen 425 ------1.5125------2.15-------1.450------1.55

Actual CPU Vload is 0.06V less than BIOS setting in all cases.

The maximum clock at all the pink (one less than red) voltages in BIOS (CPU 1.55V, FSB 1.4V, NB 1.45V)? Thatâ€™s 450MHz FSB or 3.6 GHz, but it needs all fans running at maximum which I donâ€™t want, and it fails Orhtos after a time. 438 FSB / 3.5 GHz is rock solid (see Photo 2), but requires too much voltage and fan noise

Photo 2
http://members.iinet.net.au/~gbyers/438%20FSB.jpg

Orthos (dual Prime) and ClockGen

I did have a suspicion that using ClockGen would allow some to cheat the benchmarkings. However, Orhtos reports the boot FSB frequency even after a change is made to the FSB with the PLL of ClockGen. Ha, so you canâ€™t cheat on Orthos.

Memory Settings

Using MemSet 3.0 is the easiest method of optimising your memory timings. From within Windows you can change most timings and apply them without rebooting. Obviously changing some settings will freeze the session. Once you have tested the settings you can either get MemSet to apply the settings for each session, or you can just apply the settings in BIOS. You can see the settings I ran with in the screen shot.

Other BIOS Settings

Iâ€™ve found that leaving CIE enabled does little to harm performance. This setting enables the Intel Speed Step function which allows the CPU to reduce from an 8x multiplier to a 6x multiplier when idling. Normally Speed Step would also reduce the CPU voltage, but this is disabled when using other than Auto in the BIOS for CPU voltage. As a result Iâ€™m not sure whether the savings are as great, but at least the CPU clock speed is reduced when the PC is sitting idling.

Quiet Computer

The best speed to run for quiet computing is 400 MHz FSB or 3.2 GHz CPU clock. Front and rear fans are at 1000 rpm, CPU fan is at 1700 rpm, GPU fan (Zalman) is inaudible on 5V. The two hard drives are in Scythe Quiet Drive enclosures and supported on foam rubber feet.

Upgrade to BIOS version F6.Disable automatic faw control in BIOS.Try to set memory multi @ 2,5,then drop the CPU multiplier to 6,and then increase FSB to see how far memory can go.Finally,you should have the idea of what your RAM is capable of,and then try the CPU.

P.S Thanks to Dinos22 for helping me with some advices.The memory multi was his idea,not mine.

I'm trying to clock my Ballistix @DDR2-1000 instead, got it to work at stock vdimm once w/ 3.2Ghz, but can't anymore. Need to play with that some more later. 1:1 FSB/memory gives awesome latency results though. Is someone running the ballistix faster than 4-4-4-12@800? I might try that instead of going to 1000.

Havnt run sp2004 for more than an 1 hour. Will test overnight soon. 3D benching and gaming are 100% stable so far, no random restarts.

Here's mine, been testing and tweaking for over 8 hours now, seems to be stable at 3.3GHz :). Too bad my motherboard won't go any higher than 425, then again my RAM won't go any higher than 415 1:1...although I'm very satisfied with the RAM oc results, as it's cheap value RAM.

1.4v 3.6G sp2004, could be lower vcore, haven't much time to try :)

Anymore settings you can share?
Vdimm,Vfsb,vMCH,vNB,vSB etc ...

I can hit 3.6ghz but i need more then 1.55V for it on WC setup and my NB get so hot i can't touch it. (need active cooling for it)
Anyway I still need much of testing but i'll post some results soon.

Can you post all the bios options you changed to achieve the overclock?
Because I have about the same setup but I need +1.55V to get 3.6ghz stable.

I remember simply changing the options like FreeCableGuy suggests in his P5B Deluxe thread. Really nothing more at all, so far. I hope to get the cpu further when I have some time to experiment.
