Yo guys,
before I installed my HD5970 I loaded the BIOS "optimized defaults". I have got CPU Clock Drive 700 mV, PCI Express Clock Drive 700 mV now.
If I oc my system to the clocks in the signature again would it be better to set the CPU Clock Drive up to 800 mv and the PCI Express Clock Drive up to 900 mV ?

I am running Windows Vista, Windows 7 in a 64 bit mode and Windows XP Home in 32 bit mode. What would happen to the Windows XP partition if I change the HPET Mode to 64 ?
