Why wont my CPU overclock more than 2.8ghz?!?!

post #1 of 14
Thread Starter 
I have the Intel Q6600 Kentsfield (G0). I've been trying to overclock it, but it wont go over 2.8ghz. Now I know it can go higher than that because I've seen many rigs with the Q6600 at above 3.1ghz. Why wont mine go over 2.8?! Am I overclocking it wrong??
All I do is I go to the BIOS on boot up, and increase the FSB 10mhz at a time. (Yes, I've disabled all options that limit the voltage)
AND I increase the cpu voltage a little bit when the cpu doesnt boot up as fast.

PLEASE HELP!?!?

CURRENT SETTINGS:
fsb: 1277
cpu voltage: 1.29375
(should I keep the execute disable bit on? and speedstep? because they are off)

it might be your motherboard. I know my p5n-e sli could not oc a quad at all, so it might be that the SLI 6 series boards in general just are not good at it.

Have you updated your BIOS yet?

Try to increase vcore to 1,45, fsb or vtt volt 0,20 from default, NB or MCP volt 0,20 from default and start with FSB 375 (FSB QDR 1500), multi 8 and have your memory linked and sync, then start to step up FSB (FSB QDR 20) in 5 at a time in this way you should reach 3.2GHz, that´s a start.

Good luck

OP: What model is that 680i? TR, T1, AR, or A1. The TR and AR can't overclock quads very well...

IF you don't know, the model is the last part of the product number
