III. INSTALLATION (Memory) III. INSTALLATION 2. System Memory (DRAM & SRAM) This motherboard supports four 72-pin SIMMs of 4MB, 8MB, 16MB, 32MB, or 64MB to form a memory size between 8MB to 256MB. 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 TTL 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: Memory setup is required in BIOS Chipset Setup "Auto Configuration" on page 35. Install two memory modules each time as shown in the chart below.
