PWM hard mod can someone please explain it whats the benifit

[wildstallionuk]

Hi all,

I have two GX580 Platinums in SLI. The board has an area where you can bridge the circuit to double the PWM frequency from 250 to 500.

Can someone please explain under what circumstances you would wish to do this and what the benefits are?

Unless its a particularly cold day I am stuck at a stable over clock of 928Mhz and would love to beat it. If I turn the air-conditioner on in my room I can go to MHz fine.

too high overclock -> card gets very hot -> graphical errors -> cant get into windows to change settings -> need to cool card down -> bridge connectors -> fans spin harder -> card cools down -> no graphical errors -> get into windows -> back down overclock a bit



there you go, i just made an example for you
