Hi guys. I've been a lurker for a long time but finally registered.

I recently purchased the following:

Intel i7 920 D0
ASUS P6T LGA 1366 Intel X58 ATX Intel Motherboard
G.SKILL 6GB DDR3 1600 (PC3 12800) F3-12800CL9T-6GBNQ

and a Noctua NH-U12P SE2 to cool it.

I'm just wondering if anyone has some settings for me to input into the BIOS since I'm overwhelmed by all the various settings.

Thanks for any help.

well when overclocking an i7 there are only three main settings to change
the cpu frequency/multiplier
the voltage
and the QPI link (voltage?)

for a 4.0ghz overclock i have it set to
200mhz x20 multiplier
1.30v cpu voltage
1.4 qpi voltage

you will have to find the lowest cpu voltage you can achieve, without it getting unstable during bootup/stress testing

Aren't there things I need to disable as well? I'm not sure what those are. Do I need to mess with the RAM settings?

Welcome :welcome: You're going to have to do some "reading up" on the i7 CPU and learn what you can and can't do first. I used this forum, Google articles and other forums for info and had an "understanding" of the limits before I even attempted to overclock mine and I suggest that you do the same.

Here are some articles that helped me understand what I was doing rather than just changing settings without a working knowledge of this chip. I found that overclocking the i7 is closer to the AMD cpu's than it is to it's C2D/C2Q predecessors.

Be sure to take it slow. Get your system stable with all your settings in manual mode rather than in the default auto mode before you begin overclocking. Make sure your temps are below 75 C max while under load and know what the limits of the voltage settings are (so you don't ruin a bunch of expensive hardware). Keep the uncore voltage within .5v of the DRAM voltage too but you will need to set your RAM voltage to 1.65v or so to get stable. The uncore frequency needs to be at least twice the frequency of the DRAM or 2x+1 but setting it too high will cause an unstable condition.

Good Luck and have fun at it!:beer:
