Memory Module Guidelines

CAUTION: To prevent damage to equipment or loss of information, make sure that the server is powered down, all cables are disconnected from the back of the server, and the power cord is disconnected from the grounded (earthed) AC outlet before removing the access panel.

CAUTION: To prevent damage to the system when handling components, refer to the

Figure 2-26: DDR SDRAM DIMM sockets location

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.
