VA-10 External CPU Clock

Hi, I have this mobo winth an Athlon XP 2600+ Barton, I want to overclock it
changing external clock in bios but any value is the same, once system boot
CPU frecuency under windows is 166Mhz. Any one know how can I overclock this
mobo?
Thanks in advance

Yes, you need a CPU that's not locked, like the one you've got.

Got the same problem, same board, locked 2500+ Barton.

Looks like the last AMD CPUs are all locked...
