I just did a system build with an AMD Athlon II X2 250 Regor 3.0GHz CPU and a BIOSTAR A785GE AM3/AM2+/AM2 AMD 785G Micro ATX AMD Motherboard and installed Windows XP on it. I did all the bios updates as well as Windows updates and when I checked in the system settings it said it had a 1.8ghz CPU. So I ran CPU-Z and at first it said 1.8Ghz and then suddenly dropped to 800Mhz. What is going on here? Please help.
Here are the results of the CPU-Z :
