I have a AMD 1900 (1600) processor. My HD died and when my CPU was returned Belarc Advisor shows my processor as 1200 not 1600 or 1900. How did I tweak the CMOS to get back the speed I had before?
Many programs like belarc try to read the CPU ID codes, and they can be very inaccurate. And if belarc was reading the speed, a AMD 1900+ should be around 1.2GHZ if I am not mistaken.
