I just put together AMD Athlon II X2 3ghz computer for my son. When I go to bios it will show the cpu speed at 3ghz like it should,but when I look in c-puz it is showing the cpu speed at 780 mhz with a 4x multiplyer. Which one is correct, Does c-puz have problems with some cpu's or motherboards, which is a Biostar A77OE3, AM3 motherboard. Computer seems to run just fine, but just wanted to check to make sure everything was fine before taking it over to him.
