Main Memory

The four SIMM sockets can accommodate one or two pairs of EDO SIMMs. The base configuration for main memory is one pair of 16-MB nonparity SIMMs installed in sockets J6J1 and J6J2. Main memory can be expanded using pairs of 16- or 32-MB SIMMs. The SIMMs within each pair (J6J1 and J6J2 or J7J1 and J7J2) must be the same capacity and parity type, but the two pairs need not match each other.

The system’s ECC support, which is built into the system board, corrects single- bit errors and detects all multiple-bit errors. To use the ECC support, all installed SIMMs must be parity SIMMs.
