This is my first post at toms, but I've often found the website useful to read. I am attempting to overclock my e6400 conroe from 2.13Ghz. The maximum I can currently get it to is 3.4Ghz, but id like to reach 3.9 if possible ( I have watercooling so heat isnt an issue). for a stable 3.4Ghz, here are my settings:
CPU Freq : 427mhz
CPU ratio : 8
CPU voltage : 1.475V
Mother Board : ASRock P45XE
PSU : 1000W
GPU : 2 crossfired 3850x2's
RAM : 3GB MHz DDR2
OS : Windows 7 Pro 64
I know the motherboard isn't great, and that the RAM is kinda gutless (therefore post just outlining this wont be required :-p), but there must be a way of getting higher than 3.4Ghz.
what I would do, is set your CPU multiplier down to the lowest setting and gradually raise the FSB until your computer is unstable. If you can't raise the voltage on the FSB anymore, that is your max FSB wall.
That way you can see if you are hitting a FSB wall or if your CPU is the problem.
