I'll be running an Iwill kk266 for about another day. It truly is a great kt133a board. It allowed me to run a 160fsb at the fastest ram timings. As stable as any other board as well. Correct me if I'm wrong though, but i think you would be hindering that cpu with only sdram in your system. The XP cpu's are designed to be used in ddr systems, and the limited bandwidth of sdram will really hurt you. If you are having to buy a new mobo anyway, why not go for a ddr setup. The motherboards should be roughly the same cost. The ram will cost you more, but the added performance should make up for the added cost.
