2.4 System memory 2.4.1 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 figure illustrates the location of the DDR3 DIMM sockets: 2.4.2 Memory Configurations You may install 1GB, 2GB, 4GB and 8GB Unbuffered with ECC DDR3 DIMMs into the DIMM sockets using the memory configurations in this section. UDIMM DIMM Slot Per Channel DIMM Populated per Channel DIMM Type Speed Rank per DIMM 2 1 Unbuffered DDR3 ECC 1066/1333 Single Rank, Dual Rank 2 2 Unbuffered DDR3 ECC 1066/1333 Single Rank, Dual Rank • Start installing the DIMMs from slot A1 and B1 (orange). • Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. ASUS P8B-M 2-15
