I read that overclockers "overvolt" their CPUs. Is this simply to run the processor at a higher frequency? (As a voltage controlled oscillator?) Is there any other reasons for overvolting your processor?
yeah, the reason people raise the CPU core voltage is: it increaces the stability of an overclocked CPU no, well at least i don't think there is
I suppose if you wanted to kill it. Or if you wanted to make it warmer. So, no other reason really. Just don't overvolt too far! You may damage it.
The only non-OC reason would be if the motherboard undervolts a little and it's affecting stability. I know my DFI board (it's a known issue) undervolts, so while that doesn't really affect the CPU's stability (results may vary per situation), in a case like that, it does need to be factored in. But, yeah, in general, overvolting is only done in conjunction with overclocking. No oscillator, though.
Ive got a board which overvolts all by itself! If I set it to 1.5v I get 1.55v. Nout I can do about that either. Id only ever overvolt a cpu to increase the stability of an overclock and not to get a higher clock speed.
