Hey guys this is my first overclock. So i just want to make sure I don't blow up my machine. i got my Phenom x 4 975 black to 4.2 ghz and its running about 55 degrees with prime... Is that safe and if not what is safe temps?
Try seeing how much lower you can get the voltage, that is the most direct effect on your temps,
mine holds 4GHz at 1.325v but your best setting is ofc for you to discover,
have a play about and see how low you can get the current whilst still holding 4.2GHz stable
