I am messing with OCing my CPU, but I heard that if you go above stock voltage, your CPU life will go down. If I have the voltage on "auto" on my mobo (P4P800-D), is this equivalent to stock setting or do I have to manually set it to stock voltage? Btw, my CPU is a 2.8 P4C and my RAM is Corsair XMS 2x512 MB 3200LL
