Memory Installation Guidelines

  1. The 4 SIMM sockets can accommodate from 16 to 128 MB of RAM.

  2. Supported SIMM sizes are 4, 8, 16, and 32 MB.

  3. SIMMs are 32- or 36-bit and 72-pin.

  4. SIMMs can be either fast-page mode or EDO:
  • 16 meg of memory will be EDO nonparity (standard EDO).

  • 32 meg of memory will be EDO nonparity or parity (customer's option).

  • Above 32 meg of memory will be EDO parity.
  1. Error correction code (ECC) only works if the SIMMs are parity EDO memory.

  2. SIMMs must be installed in matched pairs for connectors J3G1 and J3G2 and for J3H1 and J3H2.

  3. The number and arrangement of chips on the SIMM may vary.

  4. The SIMMs used on this system have tin leads.
