Cpu: Pentium D945 (3.4GHz)
I just used an option thT the board provided, which allowed me to pick from Overclock 5%, 10%, 15%, 20%, 30%, not doing the adjusting manually. I just jumped from one to another, if the system felt stable. Meaning, I tried 5% and if that did not lead to blue screen or non-responsive boot-up then I just cranked it up to 10% and so forth.
Well, when you oc, either you do it manually,i mean everything or predefined bios options,- which is not recommended.
Just try your oc, w/o using auto over clock in bios, only increase fsb -
