what chipset does your board use?

It should run at about here=

When you boot up, what Mhz is the BIOS saying?

Have a look at Advanced Chipset features/setup in your BIOS - make sure that the FSB frequency is set correctly. Default settings can fail safe after boards have been reset - take heart that my Athlon 3200 downgraded itself to an 1100mhz model after having to reset the BIOS, but it was an easy tweak to get it back on form. Your computer will be running ever-so-reliable on present settings, but it will also be running slowly.

click here there are known issues about incorrect reporting of amd processor speeds. A bios update usually resolves this. (tread carefully)

The correct speeds for 2600 athlons are found click here of which there are 3 variations, that's two thoroughbreds and one with a barton core.
