2.4 System memory
2.4.1 Overview
The motherboard comes with twelve (12) 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:
2.4.2 Memory Congurations
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 congurations 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.
