I was wondering if anybody could help me out I cant overclock my cpu at all. I have an Asus M4A79 Deluxe, Athlon II X4 630, OCZ reaper DDR-2 1066 8gb, XFX HD 4870 1gb, baraccuda 7200.12 640gb hard drive, BFG 550w powersupply. I also tied a Phenom 9600 with no luck.
OK what happens is everytime it try to raise the clock speed the system just shuts down I am only capable of getting up to a clock reference of 204 anything more it crashes to the bios.
Thanks for any help Dave
