Installation Guidelines
The 4 DIMM sockets on the system board can accommodate combinations of 8-, 16-, 32-, 64-, and 128-MB DIMMs up to a total memory capacity of 512 MB.
Main memory can have either 72-bit parity ECC DIMMs or 64-bit nonparity DIMMs. The DIMMs can have different capacities, but they must adhere to the
following installation rules:
l The largest-capacity DIMM must be in socket DIMM_A with decreasing capacities toward socket DIMM_D.
l ECC functionality is enabled when all installed DIMMs are 72-bit parity DIMMs and the ECC category is set to On in the System Setup program.
