As the topic states, I have an AK73(Pro) A board with the Via133 chipset. I have been trying to figure out what is the highest chip that the board supports. I looked at the CPU Support list page on the Aopen website, and it lists Athlon XP's but then says they are technically supported but worked in the test lab. By design and default what is the highest AMD Processor that it will support? Currently i have an AMD Duron 900Mhz in there and am trying to do some upgrading without spending the cash for a new system. Phaetos
