i come accross an option in BIOS for PCI-E Overvoltage.can anyone tell me if it helps with OC a 4670 in CF which is running on power from the PCI-E slot and no external power connector onboard.So what the safe voltage to go?
it only helps when you are increaseing the pci buss speed but it can be very damageing to your gfx cards also any other pci-e card u have installed eg sound card or wifi, id recomend not doing it tbh.
