Obviously I didnt do that, Can you tell me why you should do the above?Quote:

I just find that if there is any weirdness after a bios flash, this fixes it. No need to reflash, just load up the systems defaults, save & exit and then after the reboot, go back in and load up your overclock. Even better yet, manually enter in your overclock again...

Always load BIOS defaults save & reboot before you flash to a new BIOS. After, go in and either recall your saved OC settings, or manually re-enter your OC settings again...
In terms of my settings, I will list all of the ones I have changed from default configuration here...
Ai Overclock Tuner - Manual
Multiplier - 21x
BCLK - 200MHz
DRAM - 1603MHz, 7-8-7-20-1N (in BIOS, 1N == 1T)

QPI/DRAM Voltage - 1.35000V
DRAM Voltage - 1.65681V
APIC 2.0 - Enabled
ROG Logo - Disabled (irrelevant but annoying :p:)
That's it. That's all I use for my OC. Everything else is set to whatever the defaults are, including Load Line Calibration (it is on Auto by default and I left it at that).
MatroX13 - Yes, there are plenty of people that have installed WC on the board, and it installs just fine. IIRC clearance for sound cards in the top PCIE 1X slot may be an issue, but I am not 100% sure on that. I am personally not cooling with water, but if you read the whole thread you will find the information you are looking for and even some examples of people setting stuff up.

Notes: I can run @ 4.2ghz with H.T. on but Vantage and prime 95 fails. With H.T. off Vantage and prime 95 passes. (Max 58c / Min 30c idle H.T. on)
However the Vantage score is lower by 700pts than @ 4095 mhz with H.T. enabled. :eek2:
OMG... FLASHING TO THAT BIOS NOW !Quote:

I cant say it to many times.., these chips are heat factorys..! :)
Here is 2 air runs with GTX 295 PPU disabled...

I will flash 0904 (on 0903 now) and give it ago.., thx for sharing everybody!
I'm wondering if more voltage on the cpu would help me get stable at 4.2. If I leave off H.T.. It can pass vantage. You guys think HT needs more voltage on the cpu ? I know it with it on it does make the cpu warmer. Whats the max voltage you guys think is safe? 1.45-1.48v? Should I go higher if the temps are resonable ?Quote:

My 920 could hardly handle 1.5 v-core cooled with SS.., over that and throttling..!!! You must cool these chips!!!
HT is the purpose of these chips.., leaving it off kinda rips initial intention to pieces...
Try finding sweetspot for your cooling and your chip.., trying to force high clocks by cutting the legs of chip.., no.., wrong path I belive...
When you find whats best for your chip.., then the nice reults will come.., and they will be stable.., takes sometime to figure it out.., but who said it should be easy to get massive clocks just like that..?
OC is not always that easy.., it takes experience and patients.., in time.., it comes.., and there is nothing so rewarding as when you actually find your way.., and can get decent stable benchmarks.., so.., dont think that your chip is no good.., give it the chance itīs worth it...
I am getting the code BCcode 124 (BSOD) when I am at 4.2 with HT turned on . Oddly this is releated to the xfi sound card. I think I'm topped out @ 4095. Temps look good at 4.2 but Vantage locks up on me. I guess I'll hold off a wile to see what others 940 users come up with. Its got to be my voltages...I just dont know which ones atm.
Im priming right now and I will keep it @ 4.2. But i have to disagree with you. If you are gaming/general Windows Vista usage the 8 threads do absolutely nothing. I think Vista 64 runs snappier with the 4 cores. Stable for me is doing @least 4 hours of Prime95 blend. Im not the 24 hour kind......If you have speciaal needs like development then 8 threads may be interesting. I can prime @ 4.2 with turbo and ht on but i think the temps are to high and the 4 extra threads give me nothing but higher temps and higher power usage..........Quote:

@ that voltage ...those temps are not that bad . I'm having to run 1.44-45v to stay at 4095mhz.
BringerOdeath , what is your CPU PLL voltage and your QPI-Dram voltage ? I think those voltage are keeping me from 4.2 stable.
I posted about this maybe here, maybe somewhere else before, but if any of you are using X.M.P. profiles for memory do check your QPI/DRAM setting in BIOS and then actually measure the voltage on the board. If it is not the same, then your X.M.P. is not working correctly and could cause instability of the system at which point you need to stop using it and manually configure the memory the same way that X.M.P. would do it for you.Quote:

yes it is, i think he means 'ioh' [nb]
Ah that would make much more sense... by the way Jason if you read this can you post your current settings for the 4.35ghz your rocking over there? I scanned the entire thread and couldn't find your settings for that... Would be much appreciated.
actually it cpu pll defaults at 1.181
No its 1.812Quote:

Hey guys! I have a question about OC the 965 EE. Right now I just leave the BCLK at default 133Mhz and simply pump the multiplier up, talking about the simplest and laziest OC ever. My questions are should I go for a higher BCLK/lower multiplier OC instead? Are there any real benefits, performance-wise, raising the base clock?
