My Overclock:
i7-930 @ 4GHz.
vCore: 1.29
Multipliers: 19x211 (got lower temps this way, used to have 21x but the temps was higher and required higher vCore to run stable.
Turbo: Off
Temps: 60-67 degrees max load under stress, rarely goes over 63-64 in gaming, which for me is ok.
Idle: 39-43 degrees with fan on 50%
I don't see the point in going higher, and it's not really smart either. The performance over 4GHz in games are very small. I would maybe get 5-10 fps more with 4.2GHz, and when in most games I have over 100fps what's the point?
I overclocked a friend's rig. He was using a Core i7-920 in a system he built himself.
Got it up to 4.4 GHZ on air cooling alone (using the Cooler Master Hyper 212 Plus).
At idle, it lingers at 40-50 Celsius. Under load, it reaches 70-80 degrees celsius (under Prime95), though I got it to hit 91 one time.
What's your memory running at? Just curious.
BTW I'm at 3.5GHz and happy with that.
Multi 21x160 (turbo 22x160)
Turbo on
Vcore 1.1875
QPI/Vtt 1.215
Memory 8-8-8-20-1T @1600MHz @1.640v
Idle temps 42 (CPU fan running at a quiet 890 RPM idle)
Prime 95 Load temps 72 (CPU fan running at a quiet 1200 RPM load)
Memory @ 1678MHz.
But I had to raise my vCore again "sight", cause my games kept crashing to desktop with my current config, for some unknown reason.
I lowered my OC to 3.85 GHz. Seems more stable, and vcore is much lower.
It's weird you need so much more vcore with just 150MHz more.
My temps are now better too.
What QPI/Vtt voltage did/do you have?
BTW 4gig+ is nice, if it's stable. It one thing to hit 4gig, it's another to be stable across all applications
I have the QPI to auto.
Yes. For some reason 4GHz runs stable with a 21 multiplier in everything, but then it gets too hot because of the voltage: 80+ degrees
And with a 19 multiplier 4GHz runs stable with lower voltage, but then I get these game crashes after 20 minutes.
