A problem for tweakers of Athlon 754 CPUs is that neither chipset available for the processor - K8T800 or Nforce 3 -- allows you to set AGP and PCI speeds. So, when you overclock, you overclock the frontside bus, but the AGP and PCI devices have their limits.
I tried to overclock a 3400+ rated Athlon CPU, that works at 2200MHz, to close to 2365MHz with a FSB overclock of 15MHz but that was as far as we could go.
Well, this is about to change, as VIA's K8T800 PRO will be enable you to fix AGP and PCI values. This means that your PCI and AGP devices won't be over-overclocked. Bare in mind that you cannot change the multiplier on Athlon 64 or FX CPUs except if you are lucky a journo or industry man that has a rare overclockable multiplier.
This means that 939 CPUs might be good overclockers, as we saw a phase-changed, cooled Athlon FX running at more than 2800MHz from its original 2200MHz and it was still running quite cool. µ
