Yep.

I'm running one w/a 2600.

Processor settings on any modern motherboard are controlled in the BIOS, not 
with jumpers anymore. I'd suggest looking in your BIOS. There's a good chance 
the board is falling back to the lowest possible bus speed, which when 
coupled with the clock multiplier results in a processor the board thinks is 
an 1800.

I vaguely recall my secondary system (a 2400 like yours) initially running a 
100MHz bus when first installed and showing up as an 1800. When I set the 
right bus speed (133MHz) in the BIOS, the chip was recognized properly as a 
2400. Its even more fun for faster procs (like my 2600, which has a faster 
bus ;-).

Technically, this question has nothing to do with MythTV, but... It should say 
on the chip die somewhere what it is supposed to be, but I'm guessing its the 
right chip.
