Computer Memory Configurations
The server will support up to 512 MB of parity memory and 256 MB of ECC memory using SIMM sockets
0 through 7.
When adding additional memory make sure to:
♦ Install 36-bit SIMMs having an access time of 70 ns or less.
♦ Fill two sockets at a time using the same SIMM size, type, and speed (4 MB, 8 MB, 16 MB, 32 MB, and
64 MB densities are available for parity memory. 16 MB and 32 MB densities are available for ECC
memory).
♦ Fill sockets 0 and 1 before sockets 2 and 3, sockets 0 through 3 before sockets 4 and 5, and sockets 0
through 5 before sockets 6 and 7.
♦ Only the configurations listed below are allowed.
♦ Parity memory and ECC memory cannot be mixed together.
♦ Only 32 MB ( 2 x 16MB, IBM ECC) and 64 MB ( 2 x 32 MB, IBM ECC) densities are available for
ECC memory modules.
