evga p55 ftw pwm frequency

post #1 of 5
Thread Starter 
hey guys. can someone explain to me what changing the cpu pwm frequency can do for an overclock? my bios has about 5 options for this feature. The only information the bios gives me is "lower for better mosfet temps, and higher for better overclocks".

what does switching the pwm frequency actually do? does it have anything to do with power phases?

the bios also has vtt pwm frequency and dimm pwm frequency which can also be changed.

Saw this and I can't say I had anything other than a vauge understanding. A little searching and I'm not sure I'm any less vauge. LOL . Anyway this is the way I understand it. Changes the frequency of the Pulse Width Modulation power regulation. Higher frequency is more efficient, raise the frequency for cleaner power which can result in better overclock. Except that raising the frequency will also raise the VRM temps.

I take this to be more of a extreme cooling, suicide run sort of setting.

I also had this very same doubt.

As for extreme cooling I'm not sure.. the card doesn't seem to get hot at all at the stock settings on the VRMs..
I hate when something looks very important to our OC, but the more I search for answers, the more questions I get...

i leave them all on auto, every at temps with dry ice cooling. but with ln2, i do adjust, its to help with cold bugs when the temps are very low.

~sizzle~ has it right...

goes along with the X-Cool jumper.
