1055T PWM Frequency

post #1 of 2
Thread Starter 
Hi, Just messing around as usuall in my BIOS, constantly adjusting settings and disableing CPU cores when I don't need them.

Coming across the CPU's PWM frequency option in the BIOS, does it have any negative or positive affects on overclocking when your trying to achieve 4.0GHz and more? I currently have it set it 500Khz from it's default 200KHz (I believe), which I think I read somewhere that it would put strees on the CPU's PWM controller, Not sure if that's right?

Any insight would be appreciated

Moving it higher means that the capacitor drain less as they have less time between each cycle to dissapate their stored energy which would result in less ripple in the cpu voltage which in theory woulb be beneficial for overclocking. It may put a little more stress on the mosfets but the pwm controller shouldn't be affected.
