Why are you trying to overclock with software? It's a lot better to overclock using the bios...If your bios doesn't have overclocking features theres a slim chance that software will work either...
If it's your bios...and you're willing to risk...I can mod your bios and unlock the advanced features like bus speed, cpu voltage, and ram clock settings...
It's not guaranteed that I'll be able to do it...but there's a pretty good chance...I've done it before...the biggest risk is the flashing of bios going wrong but that nenevr happened to me so far...so pm me if you're interested...
