System Memory
You can upgrade your system memory to a maximum of 64 GB by installing combinations of 256-MB, 512-MB, 1-GB, 2-GB, or 4-GB (when available) 2-way
registered ECC PC2-
3200 (DDR II 400) memory. The memory sockets are located on the memory riser card(s).
The system memory is located in sockets on the memory riser card(s). See
Figure 6
-10
. The memory module sockets are arranged in two banks per riser card
on two channels (A and B). The memory module banks are identified as follows:
l
Bank 1: DIMM_1A and DIMM_1B
l
Bank 2: DIMM_2A and DIMM_2B
Figure 6-10. Memory Riser Card Connectors
General Memory Module Installation Guidelines
l
If only two memory modules are installed on a memory riser card, they must be installed in sockets DIMM_1A and DIMM_1B.
l
Two memory modules installed as a pair must have matched memory size, speed, and technology.
l
The system supports both single-ranked and dual-ranked memory modules.
l
If you install both single-ranked and dual-ranked memory modules, the dual-ranked memory modules must be installed in bank 1.
Removing a Memory Riser Card Filler Blank
If you are adding an additional memory riser card, you will need to remove the filler blank installed in the location you are adding the new riser card. (The filler
blanks are installed to direct cooling airflow if a memory riser is not installed.) To remove the filler blank, press the latch on the upper surface of the filler blank
and slide the filler blank out of the system.
Removing a Memory Riser Card Insulator
Each memory riser card has a plastic insulator that helps ventilate the memory modules. To remove the memory riser card insulator, lift the four tabs on the
edges of the insulator. See
Figure 6
-11
.
Figure 6-11. Removing and Installing a Memory Riser Card Insulator
NOTE:
A single-memory module configuration is not supported, and the maximum memory configuration depends on the availability of single-rank 2-GB
memory modules.
NOTICE:
If you remove your original memory modules from the system during a memory upgrade, keep them separate from any new memory modules
that you may have. Use only registered ECC PC2-3200 compliant (DDR II 400) memory modules.
