III. INSTALLATION
2. System Memory (SIMM)
This motherboard supports four 72-pin, 32-bit SIMMs (Single Inline Memory Mod-
ules) of 4, 8, 16, 32, or 64MB to form a memory size between 8MB to 256MB. The
SIMMs can be either 60ns or 70ns Fast Page Mode (FPM) (Asymmetric or Sym-
metric), or Extended Data Output (EDO) (BEDO & Parity are not supported). SIMMs
must be installed in pairs so that each Row (refer to motherboard layout for Row
locations) contains 64-bits of the same size and type of memory chips. One side
(with memory chips) of the SIMM module takes up half a Row on the motherboard.
IMPORTANT: Memory speed is set up through “Auto Configuration” in the BIOS
Chipset Setup of the BIOS SOFTWARE. If both 60ns and 70ns memory are used, set
“Auto Configuration” to 70ns. Do not use memory modules with more than 24 chips
per module. Modules with more than 24 chips exceed the design specifications of the
memory subsystem and will be unstable.
