2-4 Installing the Memory Read the following guidelines before you begin to install the memory: • Make sure that the motherboard supports the memory. It is recommended that memory of the same capacity, brand, speed, and chips be used.• Always turn off the computer and unplug the power cord from the power outlet before installing the memory to prevent hardware damage. • Memory modules have a foolproof design. A memory module can be installed in only one direction. If you are unable to insert the memory, switch the direction. 2-4-1 Dual/3 Channel Memory Configuration This motherboard provides eight DDR3 memory sockets and supports Dual/3 Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual Channel memory mode will double the original memory bandwidth. The six DDR3 memory sockets are divided into three channels and each channel has two memory sockets as following: Channel A: DDR3_P0_A0, DDR3_P0_A1 (For pimary CPU) DDR3_P1_D0, DDR3_P1_D1 (For secondary CPU) Channel B: DDR3_P0_B0, DDR3_P0_B1(For pimary CPU) DDR3_P1_E0, DDR3_P1_E1 (For secondary CPU) Channel C: DDR3_P0_C0, DDR3_P0_C1(For pimary CPU) DDR3_P1_F0, DDR3_P1_F1 (For secondary CPU) DDR3_P0_C1 DDR3_P0_C0 DDR3_P0_B1 DDR3_P0_B0 DDR3_P0_A1 DDR3_P0_A0 DDR3_P1_D0 DDR3_P1_D1 DDR3_P1_E0 DDR3_P1_E1 DDR3_P1_F0 DDR3_P1_F1 Channel A Channel B Channel C DDR3_P0_A0 DDR3_P0_B0 DDR3_P0_C0 DDR3_P0_A1 DDR3_P0_B1 DDR3_P0_C1 DDR3_P1_D0 DDR3_P1_E0 DDR3_P1_F0 DDR3_P1_D1 DDR3_P1_E1 DDR3_P1_F1 R-DIMM Single-Rank Single-Rank Single-Rank Dual-Rank Dual-Rank Dual-Rank Quad-Rank Quad-Rank Quad-Rank Channel A Channel B Channel C DDR3_P0_A0 DDR3_P0_B0 DDR3_P0_C0 DDR3_P0_A1 DDR3_P0_B1 DDR3_P0_C1 DDR3_P1_D0 DDR3_P1_E0 DDR3_P1_F0 U-DIMM DDR3_P1_D1 DDR3_P1_E1 DDR3_P1_F1 Single-Rank Single-Rank Single-Rank Dual-Rank Dual-Rank Dual-Rank Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode. 1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed. 2. When enabling Dual Channel mode with two or four memory modules, it is recommended that memory of the same capacity, brand, speed, and chips be used for optimum performance. - 17 - Hardware Installation
