What happens when you switch the =20 slots the sticks are in? Are the sticks the sam brand? Are the =20 brands/brand supported? http://www.sis.com/support/support_memory_3.htm Are you overclocking? intersresting read on the sis memory controller http://www.lostcircuits.com/motherboard/asus_p4s333/ I also find it hard to believe you have a bad mptable. Maybe you could =20 check for a new bios? It is kind of funny if sis used the ms acpi =20 tools and not intels for an intel system.
