I have an MVP3G5, which is exactly identical to your board, only with 2MB of L2 Cache rather than 1MB. With the newest BIOS available on the Epox website, I have been running my K6-3+ 450 stable at 600Mhz for a few months now, and haven't had any problems with it at all! I upgraded from a K6-2 500@550Mhz and have noticed a HUGE difference in system performance! I highly recommend this chip for anyone who doesn't want to (or can't) upgrade their motherboard to move to the Duron/Athlon lines of processors! 🙂
