Hi All,
First time over-clocker here. Been reading up and found some settings that seemed to work for me:
RAM: 2 kits of OCZ: Newegg.com - OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model OCZ2RPR10664GK - Desktop Memory

overvolts this way to much. Optimal range for overclock would be 1.2-1.5 depending on Vcore, try
to keep at least .1 under vcore. Auto is fine if not overclocking
CPU PLL…………………....1.500V*.......: 1.500V<< If overclocking Please set to stock, Auto overvolts

I was able to run Prime 95 for about 8 hours stable when the comp stopped responding, I was recording the temps and the highest Cores (0+1) were at 59 and would max at 60. I am wondering if you have any advice.
CPU-Z reports a lower voltage. Anyone have any help for me?
