u can try vmod the mobo.. google for info.
but imo asrock mobo will adjust the voltage automatically. maybe u'll have option something like normal,high,turbo.. whatever.
for stock cooler 3.2Ghz is already limit i think.
i used to have northwod 2.4 can clock up to 3.4Ghz but after 1 month my electrical increase by 50% then i change to AMD. i still kept my northwood 2,8 but rarely boot it. I think prescott can go much higher if u have better cooling and psu. but rather than invest to a good psu and cooling better u just re-built ur pc for cheap core duo now. higher performance and cool running.


p/s asrock still consider better than asus vm mobo. its really suck
