I'm new here. Interested in some of the finer points of overclocking my new i7 920. So far have a nice stable OC @ 3.8 GHz (stable defined as running all day on prime95 8 thread test). Can go higher but it gets too hot. I do lots of number crunching, CPU intensive stuff, so I'm really appreciating the speed of this system, and the 8 threads. Also good for games
Here's a summary of what I'm playing with at the moment (I'd put it in a signature but it seems us newbies aren't allowed signatures...)
i7 920 @ 3.8 GHz (multiplier 12-20, bclk 190, VCore = 1.27, everything else auto)
ASUS P6T Deluxe
Corsair Dominator 12800 @ 1530 MHz, 7-7-7-20
2 X GTX 260
ASETEK OEM liquid cooler (not recommended)
COSMOS S full tower
What I'd like to learn about here is what fine tuning I can do on some of the voltage and timing BIOS settings to get stable overclocks at lower VCore. At the moment I can go higher than 3.8 but my suck@#$se ASETEK cooler starts maxing out on temperature.
At 3.8 GHz with Prime95 running on 8 threads, I'm getting cores stabilizing at ~80 C, which seems hot compared to results others are getting with air. Idles in the mid 30's in ambient mid 20's, and under normal heavy use stays around the high 60's/low 70's.
