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

Compaq ProLiant ML350 Generation 3 Server Setup and Installation Guide.

CAUTION: When handling a memory module, be careful not to touch any of the contacts.

Doing so may damage the module.

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.
