Righty, here's the problem.

My brother's Athlon XP 2800 (Barton) is underclocked to 1250mhz.

Now to save you Wiki'ing it it runs on a 1.65v core, speed is 2083mhz, 333mhz FSB, 512kb L2, 12.5x multiplier.

The FSB on his Gigabyte GA7NNXPV has been set to 100mhz (200DDR) and the CPU is running at 12.5x100 (1250mhz)

Even when I set the FSB to 166mhz in the BIOS, CPU-Z and Windows both read it as 1250mhz, FSB100.

The BIOS still recognises it as 166mhz even when CPUZ recognises as 100.

Any ideas?

I suspect you have a jumper on ur mother board that is in the wrong position,, I think they call it safe mode,,, or there is another setting in your BIOS that needs changing.
If you are not too scared take a look at the latest BIOS for that board & upgrade if necessary.

No jumpers on the board, no 'safe mode' either.

Thanks, that seems to be the it doesn't it. I'll try it later on. None of the pictures of the board I could find were clear enough to see jumpers, and I don't think he can tell the difference between a jumper and a 2 pin plug of some sort.

Thanks again for all your help.
