System Memory

The six memory module sockets can accommodate from 256 MB to 16GB of registered ECC PC2-3200 (DDR 2 400) memory. The memory sockets are located on

the system board adjacent to the power supply bays. See Figure6-1.

You can upgrade the system memory by installing combinations of 256-, 512-MB, 1-GB, 2-GB, and 4-GB (when available) registered memory modules.

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 DIMM1B.

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 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6-7.

Figure 6-7. Determining a Memory Module's Capacity and Rank



Spare Bank Support

If six identical single-rank memory modules are installed, the memory modules in bank 3 (DIMM3_A and DIMM3_B) can function as a spare bank if you select

the spare bank option using the System Setup program.



Memory Mirroring Support

The system supports memory mirroring if identical memory modules are installed in bank 1 and bank 2, and no memory modules are installed in bank 3.

Table6-1 and Table6-2 show examples of different memory configurations. Table6-2 lists the various allowable combinations of single- and dual-ranked

memory modules.

Table 6-1.SampleMemoryConfigurations

NOTE: The memory modules must be PC2-3200 compliant.

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 DDR II memory modules.

NOTE: All six memory modules must be single-rank modules, identical in size.
