I've just changed my celeron 3.33 GHz CPU to a E7600 Core2duo 3.06Ghz. And now it is becomming wierd. At startup my BIOS is pronouncing 12.69GHz! CPU-z: 1.6GHz (SpeedStep?) and cpuspeed.exe at 3.07GHZ. I'am concerned that my BIOS is frying my new CPU. What can I do?
Hmmmmmm.. odd! I don't know the reason.
However, I suggest that you get a new MB as your MB is too old which supports only up 2GB DDR2-667.
Get an immensely cheap G31
MB from a quality company, such as Asus and Gigabyte, if you don't intend to do some extreme OCing.
My suggestions are Asus P5KPL-CM and Asus P5KPL-AM.
