Your processor has a slower fsb than your memory so that will be the bottleneck at this time. It seems that your mobo will support Northwood processors with the 400 mhz fsb,they go as high as 2.8ghz at newegg. However, I don't think that your mobo will support the newer northwood or prescott processors, so the best option would be to look for a mobo+cpu combo on the net.
