CPU PLL Voltage - 1.6
FSB Termination Voltage - 1.5

try that and what kind of PSU you have?

also try to see if you still get lockups after you set the AI clock twister to Auto instead of Strong and booster to Auto

Thanks for the advice.

I changed CPU PLL Voltage to 1.6, FSB Termination to 1.5. I left AI Clock twister Strong and Booster - 2. My PC seems to be stable now. It has not locked up yet.
