2.3 System memory
2.3.1 Overview
The motherboard comes with four 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 gure illustrates the location of the DDR3 DIMM sockets:
2.3.2 MemoryCongurations
You may install 1 GB, 2 GB, 4 GB, 8GB Unbuffered with ECC DDR3 DIMMs into
the DIMM sockets using the memory congurations in this section.

• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor.
• Install the DDR to the A2 or B2 (orange slot) when installing only one
memory module to the motherboard.
