Hey, I have AMD Sempron 145 processor. My motherboards model number is- DIGILITE DL-M61PMP-K. I want to unlock second core of my processor but i have trouble in unlocking it. I read in another forum that you cannot unlock cores with an nVidia chipset. And the main thing is I can't find Advanced Clock Calibration in bios . I think my motherboard does'nt have that option to unlock it. Is there any other method to unlock it ?
