HI. I have an asus a7s333 mobo. It says I can use either pc2100 or pc2700. I am using 512mb pc2700. When checking with SIS Sandra it says I am running at 266. I thought the spd would automatically set for 333. I guess it doesn't. Anyone can give me an idea how to set this up in the bios? I have an xp2200 cpu. Bios cpu/pci freq is set at 133/33. Cpu freq is now (default I guess) at 13.5. Thanks
