2.4System memory
2.4.1Overview
The motherboard comes with six 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:

*Support Low Voltage DIMMs; **Down from 1066 or 1333 MHz DIMM
•Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the same vendor. DO NOT combine RDIMM and UDIMM.
•The motherboard supports x8 DRAM Only and x4 & x16 DRAM are not supported
