The following guidelines must be followed when memory modules are being added or
replaced:
•
DIMMs must be industry-standard 184-pin PC2700 333-MHz DDR registered 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.
•
DIMM sizes supported are 512 MB, 1 GB, and 2 GB, allowing a total of 8 GB maximum
system memory (2 GB in each of the 4 DIMM slots).
•
DIMM sizes may be mixed on the system board. HP recommends starting at slot 1 and
filling the slots in order with the largest size first.
•
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).
•
Supported DIMM configurations are one single DIMM, one pair (two DIMMs), or two
pairs (4 DIMMs). The configuration of 3 DIMMs is not supported in this server.
•
Do not mix ECC and non-ECC DIMMs. Use only ECC DIMMs in the server. If different
types of DIMMs are mixed, the server will not properly function.
•
A DIMM will only fit one way in the socket. Be sure to match the two key slots in the
DIMM with the tabs in the DIMM socket. Push the memory module into the DIMM
socket, ensuring that it is fully inserted and properly seated.
