i7 920 overclocking thread

[ya mother]

4.7ghz ht off.

[Daveros]

Just tried my hand at my first ever bit of overclocking yesterday.

3.22GHz (161 x 20: Turbo Off: HT on) @ ~1.14 VCore. 10 hours stable Prime95 (ran overnight), will see how it is when I get home from work. Ran it yesterday at 1.125 but one thread in Prime95 failed after 8 hours. I'm quite optimistic with this effort.

Temps of around 55-60C under full load. Don't want to push it too much further as yet.

Hi guys - I've got a quick question.

I've got a D0 920 on a P6T Deluxe with 6GB of OCZ 1600 DDR3 that is prime 95 stable (13 hours) at 4.2 GHz (200*21) at a BIOS set vCore of 1.39375volts, which drops to 1.336v under load in P95 and betwen 1.32 and 1.36v under Intel BurnTest. Max temp on the hottest core was 67C (Megahalems with push-pull).

4.3GHz seems to need approx a BIOS set 1.41875v which drops to 1.360 under Prime 95.

I had not expected to need this much vCore, but given that the temps seems pretty good, and the amount of droop between the BIOS set voltages and the voltages in windows do you guys think these are acceptable vCore values? We had hoped to do better than this with our D0s, but could be happy with 4.3 if these voltages aren't too out of line for 24/7 use.

This is my first 1366 OC session so the BCLK/Uncore/QPI etc are new to me but from what I understand, it seems that once you set QPI/DRAM to 1.35, PLL to 1.88 DRAM voltage to 1.66, CPU Skew to 300 ps, CPU Amp to 800 that there isn't much more you can do other than adding vCore. . .is that correct?

Stable @ 24hrs! Hooray! My first ever OC!!!

Dear All, I'm new on this Web. I Just built my pc and was thinking about over clocking. Max Load cpu Temp is 59C. I guess I need a power full cpu cooler.

I was thinking about air cooling, not water cooling as here in summer it goes up to 42C and I was told that with water cooling at those temperatures i will be rather heating my cpu rather then cooling it down....

Any suggestions about which cooler should I get as my first step of over clocking from 2.66 stock to 3.8-4.0Ghz.

Here's my voltage, I got BSOD101 if I set vcore lower than 1.356



I'm worried about my voltage, am I doing it right?

It's stable (p95, linx, occt)

but I was wondering what could I do to lower vcore?

i answered this in your thread you made. should avoid posting the same thing twice. ;-)

Well, it's reading out as 1.26v which is a fine voltage for that speed. Maybe you could try turning on LLC to get rid of some vdroop/drop.

I hit 4.2ghz using the "EZ OC" option on my BIOS, but its not stable at all so I'm going to try to do it manually -_-
