Ok, mow Im sure everyone here is tired of reading threads about overclocking. I apologize for adding another, but I just want to make sure I get the concept.

E8400
EVGA 780i
4GB DDR2 800mhz
8800gt
750 psu




Now if I am understanding this correctly, I would have to down clock my RAM first. Then I could OC my FSB which would then raise the clock on the cpu and the RAM. Correct?
And what is this vcore? I have read multiple articles about this and I must be stupid because Its not dawning on me. Any help would be appreciated.

Correct, u need down clock ur RAM because the FSB is linked with the RAM and when u rise it the RAM clock rise too.

For the voltage is another similar thing, u need rise the voltage for stability of the rig BUT not above1.3625V that is the recommended by Intel.

The one good think about Nvidia chipsets is that you can totally unlink the RAM from the FSB so you can just leave it at 400mhz base clock and just keep it unlinked.

Chances are that you'll not need to up the CPU voltage if you are overclocking to 3.6 or below on that E8400. Many many cases where a simple FSB push to 400 did the trick.

Do you know a safe voltage to raise a phenom 2 955 be to?

Thankyou gents. Going to take my time doing this. Got it up to 3.1ghz right now and everything seems normal. Temps went up a little but that is expected. I plan on stress testing in a day or so. Does anyone know where to get prime95 or 3dmark? (i dont want to fill out an email address)

And SAA thanks for telling me about the unlink feature. Works wonderfully
