System Memory
You can upgrade your system memory to a maximum of 16 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 system board adjacent to the power supply bays. See
Figure 6 -1 .
The system memory is located on the system board adjacent to the power supply bays. See Figure 6 -1 . The memory module sockets are arranged in three
banks on two channels (A and B). The memory module banks are identified as follows:
l Bank 1: DIMM1_A and DIMM1_B
l Bank 2: DIMM2_A and DIMM2_B
l Bank 3: DIMM3_A and DIMM3_B
General Memory Module Installation Guidelines
l If only one memory module is installed, it must be installed in socket DIMM1_A or DIMM1_B.
l If two or more memory modules are installed, they must be installed in pairs of 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.
l Dual-ranked memory modules are not supported in bank 3.
l If dual-ranked memory modules are installed in bank 2, you cannot install any memory modules in bank 3.
Memory modules marked with a 1R are single ranked and modules marked with a 2R are dual ranked. See Figure 6 -15 .

CAUTION: See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting
against electrostatic discharge.
NOTE: Filler brackets must be installed over empty expansion-card slots to maintain FCC certification of the system. The brackets also keep dust
and dirt out of the system and aid in proper cooling and airflow inside the system.
NOTE: Two-way interleaving is not supported in the 256-MB single memory module configuration.
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.
