A friend has a spare Asus P4PE-X mobo and wants to use it for a new system. It has the i845PE chipset but Asus says it supports an 800mhz CPU. If anyone has this mobo, I would like to know what P4-800mhz CPU and PC3200 (DDR400) memory you are using. Also, Asus support page says to "Apply only one DIMM" when running at 800mhz; is this correct? I was thinking he could use a P4-2.6 800mhz and 1-512mb stick of PC3200. Suggestions?
