Mine says:

AMD 64 X2 Dual

Core Processor 4800+

2.86 GHZ  2.00 GB Ram

This means I have two cores running at 2.86.  I OCed my FSB to squeeze a little more power out of my machine.  I had it running at 3 GHZ X2 but it was unstable.

Make sure your machine is setup right.  Check the multiplier and the FSB.
