Core i7/X58 Overclocking Thread

[herderien]

P.S. I finally stabilized the 920 at 4.0Ghz on the P6T Deluxe I will post some pics in a bit after I prime for a few more hours but I got 3 hours of prime95 in now and it looks like it's finally stable..

i'm really really interested in seeing ALL your settings :p

1.2V loaded.

Nice chip metroid, now go for 4ghz.

I'm priming it 4Ghz at 1.25V. It boots at 1.20V no problems runs a little and suddenly freezes. I need to adjust some settings.

You won the lottery, 8 threads 4.0ghz at 1.20V.

How many minutes priming so far?

The Processor running for 2 hour, and no problem.

common guys WTF
you are supposed to be quoting batch# particularly with these crazy overclockers

sick man, could you post your mobo voltages?

Thanks..

One question.

BCLK - 211 What voltage do you have to raise to attain this number? I read that you had to raise vtt. The highest BCLK I was able to attain was 205-207 and that is with 1.35 vtt(roughly).

my 211 bclk could also be acheived with vcore 1.312v HT disabled.

The cpu is stable at 4010Mhz with 1.20v.



Very good!

I'm having issues with Prime95.

I've had my i920 OCed to 4.2 and played online for like 3 hours, no reboots, no lockups, etc.

When I run Prime95 small FTT, I get it freezing on me in like 1 min.

I've raised Vcore even to 1.48 for 4.2 Ghz and still the same thing.

I think I may know what it may be. Tell me what you think.

I am using Gskill 7-7-7-18 1.9V memory.

My memory settings are on auto, but I think it is trying to run 1600 MHz on like 1.6 V, which I think is causing the instability when all 4 core are being stressed.

What do you guys think?

I've ordered some OCZ gold 8-8-8-24 1.65 1600MHz memory which should be arriving next week.

I've run Prime 95 on stock and it works flawlessly, but then again the memory is not clocked to 1600.

So, one way to test this theory would be to lower the Mem ultiplier to 6 and see if I still have that problem?

I manually set by bios Qpi/Vtt at 1.28v. I have no problems of stability.

So I'm not far away from you Joking

Voltage Bios: 1.27,5V Windows: 1.27,5V, no Voltage drop right here

I still need to make more tests,

Thanks for the ups

+1 I'd like to see that as well.

Where did you get your i7 920, what retailer?
