i am having some trouble overclocking my athlon xp2000+. my motherboard is a jetway v266b based on a Via KT266A chipset. i have acess to the fsb speed and can overclock from there but i also want to use the multiplier. i know that i will have to connect the L1 bridges on the chip to physically do this but there is no actual bios option for setting the multiplier. is it a hidden feature that can be unlocked or will i have to upgrade my bios? if so then from where?
