I have Dell Precision 390 with a Core 2 duo e6600 i975 chipset and socket 775 LGA and DDR2-667 MHz 1*2=2gb ram. as you know that i cannot overclock it from bios cause its a OEM, So help me using a software. And using the stock cooler to overclock. Which software is best for Overclocking Core 2 Duo's? i want it from 2.4 to 2.5 in stock cooler.
