2.4 System memory 2.4.1 Overview 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: Chapter 2 Recommended memory configurations One DIMM: You may install one memory module in slot A1, B1 or C1 as a single-channel operation. Two DIMMs (dual-channel operation): Three DIMMs (triple-channel operation): DIMM A1 DIMM B1 DIMM A1 DIMM B1 DIMM A1 DIMM B1 DIMM A1 DIMM B1 DIMM A1 DIMM B1 DIMM C1 DIMM A1 DIMM B1 DIMM C1 Four DIMMs (triple-channel operation): DIMM A1 DIMM B1 DIMM C1 DIMM A1 DIMM B1 DIMM C1 Six DIMMs (triple-channel operation): DIMM A2 DIMM A1 DIMM B1 DDIIMMMM AC21 DIMM A1 DIMM B1 DIMM C1 DIMM A2 DIMM A2 DIMM A2 DIMM A1 DIMM A1 DIMM A1 DIMM B1 DDIIMMMM CA12 DIMM A1 DIMM B1 DIMM B2 DIMM B1 DIMM AC2 DIMM AC1 DIMM B2 DIMM B1 DIMM B2 DDDDDDIIIIIIMMMMMMMMMMMM BCCAAB121122 DIMM B1 DIMM C1 DIMM C2 DIMM C2 Due to Intel CPU spec deDfiIMniMtioCn1, the sysDteIMmM wC1ill not boot if only one DIMM is installed in DIMM slot A2, B2, or C2.
