I have EPOX 8HDA 3 board with Phoenix BIOS, KT800 chipset and Athlon 3000+ 2GHz. Is it possible to change to Athlon 3400 2.47GHZ. I have not been able to find a list of supported CPU for this board. It's an old machine still working fine and is only used for file backups and occasional internet use, but I would like to speed it up a bit.
