I am using this CPU for past 3 years, now decided to unlock the 4th core (kind of an upgrade). Anyway I unlocked the core in the BIOS and rebooted. The BIOS is fine it shows the processor as X4 B25 and loads up the boot loader. But when I select the OS it does not boot. So I figured it must be a voltage problem so I increased the voltage to +100mV i.e. in steps of .025 V. It is still not booting. My question is how high can I go without damaging my CPU? Is 100mV not sufficient for the unlocked core?
