2.4 System memory
2.4.1 Overview
The motherboard comes with eighteen (18) Double Data Rate 3 (DDR3) Dual
Inline Memory Modules (DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR2 DIMM but is
notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules
are developed for better performance with less power consumption.
The figure illustrates the location of the DDR3 DIMM sockets:
2.4.2 Memory Configurations
You may install 1 GB, 2 GB, 4 GB,or 8 GB Registerd or Unbuffered with ECC/
Non-ECC DDR3 DIMMs into the DIMM sockets using the memory configurations

• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor.
• For CPU1 configuraton, when installing only one DIMM, install it to the
orange slots labeled DIMM_A1, DIMM_B1, or DIMM_C1.
For CPU2 configuraton, when installing only one DIMM, install it to the
