I need some help, i installed an amd 4170 4.2ghz processor into my computer, this was an upgrade from my 4100 3.6ghz one, booted up fine and then i had random restarts. I returned the bios back to its default and its booted up fine and yet to restart. My problem is though the processor is now running and 2800mhz on 124w. Whats happened!? How can i get the 4.2ghz i wanted.
