Yep, looked up a review on your board, it supports Coppermines, therefor it also supports Tualatin voltage levels (VRM 8.4), so a Upgradeware Slot-T adapter ($20) will allow you to upgrade. If you were considering overclocking an inexpensive Celeron Tualatin, I suggest the 1.0 (256k) or 1.1GHz (256k) speed CPU to start with, as you're more likely to reach bus speeds of 133MHz or more with their lower multiplier.
