System Memory (DRAM & SRAM)
This motherboard supports four 72-pin SIMMs (Single Inline Memory Modules) of
4MB, 8MB, 16MB, 32MB, 64MB to form a memory size between 8MB to 256MB.
The DRAM can be either 60ns or 70ns Fast Page Mode (Asymmetric or Symmet-
ric), Extended Data Output (EDO), or Burst Extended Data Output (BEDO).
SIMMs
must be installed in pairs so that each bank contains two of the same size memory
modules.
To support ECC, you must use
true
(opposed to phantom parity gener-
ated 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.
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 Slots 1&2
72-pin FPM, EDO, BEDO SIMM
Bank 1
4MB, 8MB, 16MB, 32MB, 64MB
x2
SIMM Slots 3&4
72-pin FPM, EDO, BEDO SIMM
Total System Memory
=
IMPORTANT:
Each bank must have the same size and type (FPM, EDO,
BEDO) of memory installed in pairs.
IMPORTANT:
Memory setup is required using “Auto Configuration" in
Chipset Features Setup of the BIOS SOFTWARE.
IMPORTANT:
Each bank must have the same size memory installed in pairs.
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 sub-
system and will be unstable.
