unless you're pushing the FSB higher, the motherboard shouldn't be effecting it at all. If you're simply raising the Multiplier you will hit the CPU limit not the mobo unless you simply can't add anymore Vcore to it
Yes we are talking about the 2600+ Barton Athlon Xp. the multiplyer is locked and al li can do right now is raise the FSB but the vcore is defaulting at 1.8 and i dont think it is gonna let me change it. This mobo used to be good but it aint anymore!!
