Memory Configuration
The server board provides four DIMM sockets across two channels, Channel A and
Channel B.
- Channel A consists of DIMM sockets A1 and A2.
- Channel B consists of DIMM sockets B1 and B2.
DIMM Population Rules
To ensure the dual channel operating mode, install either:
■ two modules, in the slots DIMM_A1 and DIMM_B1,
■ or four modules.
Note:
■ The installation of three modules is not supported.
■ The motherboard BIOS supports single DIMM mode opera-
tion although this is generally not recommended for “perfor-
mance” applications. This configuration is only supported
with a 1 GB DIMM installed in DIMM slot A1.
Use DIMMs of identical size and speed.
Supported memory
DIMMs must meet the following requirements:
- Use only DIMMs with DDR2 DRAM technology.
- Use only DDR2-800 stacked DIMM modules.
