Another thing to keep in mind is that if you can mix, you'll probably slow your system down. Most motherboards that allow mixing will run at the slower SIMM speeds. I.e. SDRAM typically less than or equal to 12ns, SIMMs typically less than or equal to 60ns, the result is the overall machine will run its memory bus at the 60ns mark. > Actually, refer to your mommy board manual; I have an Iwill board from a while > back that has been cohabitating a SDRAM DIMM and 2 SIMMs for well over a year > now; but the ASUS board in the game machine specifically says not to (The Iwill > manual says it is OK.) > > When in doubt: RTFM :) > > Jamie > > > That is a hardware issue.
