Looking atthis, it seems that either your Clock MP is too low, or as what you already mentioned, the FSB is set too low in the BIOS.
Is the Clock MP set to the higest available in the bios?
The XP3000+ runs at aprox. 2100MHz and doesn't have an unlocked MP, so if the 10.5 is the max you need to raise the FSB.
2100/10.5 = 200
If set to 200 it should run just fine.
