The following guidelines must be followed when memory modules are being added or
replaced:
• DIMMs must be industry-standard, 128-MB, 256-MB, 512-MB, 1-GB or 2-GB,
3-cm (1.2-inch), 184-pin PC2100, DDR ECC memory DIMMs. The DDR memory
DIMMs must support CAS Latency 2, CL=2 or greater. They must also contain the
mandatory Joint Electronic Device Engineering Council (JEDEC) Serial Presence Detect
(SPD) information.
• If two-way memory interleaving is desired, identical DIMMs must be installed in socket
pairs. DIMMs installed in Pair A (sockets 1 and 2), however do not need to be identical
to the DIMMs in pair B (sockets 3 and 4). If the two DIMMs within a pair are not
identical, the system will automatically run in non-interleaved mode.
• DIMMs installed in the server must be registered DDR, 3.3-volts, 72-bits wide.
