Hi all!
I recently bought the EP45 Extreme along with the E8600 CPU. I have serious problems with my overclock.
I cannot get 500FSB x 10 mult. The highest I have gone is 4.7GHz (523*9) after that the computer almost does not start (I can see the system restart several times even before reahing the BIOS screen). Nothing over 523FSB works... I tried 523*10 but no luck...

I have tried increasing the FSB, lower it, change the multipel, Vcore, MCH core and some other voltage tweaks in BIOS.

My system: EP45 Extreme with water cooling.
F7 bios. 4GB PC8500 (1066MHz)
E8600 CPU. (water cooled)
Nvidia 8800GTS (512mb) - also tested with ATI 3850.

I appreciate any help and hints!
