Maybe this is a really generic question but I found no answer, and Q6600 is a really popular CPU.
I've tried the HOWTOs on Google, all the stuff I could find.
However, once I set some higher FSB (can't set spread spectrum.. it won't let me), the PC won't boot, have to reset bios. I could set the CPU voltage to +0.125 ..but with only that, I'm at the same place just with more voltage.
(Why would I overclock?
1) Q6600 is a CPU made for overclocking. At least a lot of people use it on 3.0+ ghz.
2) CPU speed is the only bottleneck for me and it's very annoying.
3) Have no money for a full i7 upgrade. :/)
I know , Superuser is for Software related questions.. mostly. This is ..well ... kinda connected to software. If you disagree, please point me to the right "Expers exchange site". Thanks.
