Hi i jsut overclocked my phenom x4 9850 from 2.5ghz to 3ghz just by changing the multiplier from 12.5 to 15 didnt touch the voltages or nothing i have a big cooler on it so it never gets hotter than 50 degrees all i have done to test it is run it with a program at 100% load for half and hour im going to let it run longer but if my pc doesnt crash or overheat or anything does that mean i have a stable overclock??
