Hello All, I'm new to Techspot and having an issue I think. I have a Machspeed p4mst-890 socket 775 mb. just purchased two 2 gb pc4200 sticks. When first booting pc ddr dimm speed only reads 132. How can I adjust that as I thought they were 533 mhz. also my fsb is only running at 250 mhz. can I change those through bios. Vista exprience rating for memory only reads 4.1 and I think it should read a little higher than that. Any help would be appreicated and thanks
