III. INSTALLATION 2. System Memory (SIMM) This motherboard supports four 72-pin, 32-bit SIMMs (Single Inline Memory Modules) 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 Symmetric), or Enhanced Data Out (EDO) (BEDO & Parity are not supported). To support ECC, you must use true (opposed to phantom parity generated by logic chips) 36-bit parity-type DRAM (e.g. 8 chips + 4 parity chips) in pairs for all modules. Mixing 32-bit non-parity DRAM (e.g. 8 chips) and 36-bit DRAM (e.g. 12 chips) will work minus the ECC feature. SIMMs must be installed in pairs so that each Row (see Map of Motherboard 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 setup is required through "Auto Configuration" in 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.

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 Enhanced Data Out (EDO) (BEDO & Parity are not supported).
To
support ECC, you must use
true
(opposed to phantom parity generated by logic
chips) 36-bit parity-type DRAM (e.g. 8 chips + 4 parity chips) in pairs for all mod-
ules.
Mixing 32-bit non-parity DRAM (e.g. 8 chips) and 36-bit DRAM (e.g. 12
chips) will work minus the ECC feature.
SIMMs must be installed in pairs so that each Row (see
Map of Motherboard
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 setup is required through "Auto Configura-
tion" in BIOS Chipset Setup
of the BIOS SOFTWARE.
If both 60ns and 70ns
memory are used, set "Auto Configuration" to 70ns.
Do not use memory mod-
ules 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.
