Problem with E6600 Voltage

post #1 of 3
Thread Starter 
I've been working for a while on overclocking this system:

E6600, 2 gigs pc6400, Zalman Cooler, Gigabyte GA-965p-DQ6.


Heres the thing, by gradually increasing the FSB I can get it to about 420 or so with a 9x multiplier. Heres a snapshot of my overclock settings.




It boots into windows and runs fine up to 3.7 ghz but when I shut down it doesnt boot back up.

379 is the highest FSB I can get and be able to boot up from a cold shutdown.

I actually get the bios up to about 395 and then increase the fsb through EasyTune in Windows to get to 3.7.

The other thing is I have raised the VCore up pretty high in the bios (1.65 or so) but in CPU-Z it always shows around 1.2v. Pretty wierd.

So what does this mean if I can boot into windows stable directly after changing the bios, but not when shutting down and starting the computer fresh?

Does this mean there there is a particular location I need to increase voltage to?

Using easytune and the bios can cause conflicts. Also I believe on gigabyte boards there was a bios update that fixed cpu-z not reporting values correctly.

I am using the latest bios (F10).


Is it common for windows to boot at a high FSB but the computer not boot with the same settings after a shutdown?
