(System Memory)
2. System Memory
This motherboard supports six 72-pin SIMMs (Single Inline Memory Modules) of
4MB, 8MB, 16MB, 32MB, or 64MB to form a memory size between 8MB to 384MB.
The DRAM can be either 60ns or 70ns Fast Page Mode (FPM) (Asymmetric or
Symmetric), Extended Data Out (EDO), or Burst Extended Data Out (BEDO).
SIMMs must be installed in pairs so that each bank contains two of the same size
memory modules. Maximum memory size of each memory bank must be 128MB
or less. To support Error Checking and Correcting (ECC), you must use true (op-
posed to phantom parity generated by TTL chips) 36-bit parity-type SIMM (e.g. 8
chips + 4 parity chips ) in pairs for all modules. Mixing 32-bit non-parity SIMM (e.
g. 8 chips) and 36-bit SIMM (e.g. 12 chips) will work minus the ECC feature.
IMPORTANT: Memory speed setup is required in BIOS Chipset Setup "Auto
Configuration."
Install memory in any or all of the banks in any combination as follows:
Bank Memory Module Total Memory
Bank 0 4MB, 8MB, 16MB, 32MB, 64MB x2
SIMM Sockets 1&2 72-pin FPM, EDO, BEDO SIMM
Bank 1 4MB, 8MB, 16MB, 32MB, 64MB x2
SIMM Sockets 3&4 72-pin FPM, EDO, BEDO SIMM
Bank 2 4MB, 8MB, 16MB, 32MB, 64MB x2
SIMM Sockets 5&6 72-pin FPM, EDO, BEDO SIMM
Total System Memory (Max 384MB) =
IMPORTANT: The same size and type (FPM, EDO, BEDO) of memory must
be installed in pairs so that memory modules are not mixed in each bank. 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.
