III. INSTALLATION

2. System Memory (DRAM & SRAM)

This motherboard supports eight 72-pin SIMMs of 4MB, 8MB, 16MB, 32MB, or

64MB to form a memory size between 8MB to 512MB. The DRAM can be either

60ns or 70ns Fast Page Mode (Asymmetric or Symmetric) or EDO. 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.

IMPORTANT: Each bank must have the same size memory installed in pairs.

IMPORTANT: Memory setup is required in BIOS Chipset Setup "Auto Con-

figuration" on page 36.

IMPORTANT: 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 cause unreliable operation.

Install memory in any or all of the banks in any combination as follows:
