1-4 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. (Go to GIGABYTE's website for the latest supported memory speeds and memory modules.) • 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. 1-4-1 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 four DDR3 memory sockets are divided into two channels and each channel has two memory sockets as following: Channel A: DDR3_P0_A0, DDR3_P1_D0 Channel B: DDR3_P0_B0, DDR3_P1_E0 Channel C: DDR3_P0_C0, DDR3_P0_C1, DDR3_P1_F0,DDR3_P1_F1 DDR3_P1_D0 DDR3_P1_E0 DDR3_P1_F0 DDR3_P1_F1 DDR3_P0_C1 DDR3_P0_C0 DDR3_P0_B0 DDR3_P0_A0 Channel A Channel B Channel C DDR3_P0_A0 DDR3_P0_B0 DDR3_P0_C0 DDR3_P1_D0 DDR3_P1_E0 DDR3_P0_C1 U-DIMM DDR3_P1_F0 DDR3_P1_F1 Single-Rank Single-Rank Single-Rank Dual-Rank Dual-Rank Dual-Rank GA-7PCSL Channel A Channel B Channel C DDR3_P0_A0 DDR3_P0_B0 DDR3_P0_C0 DDR3_P1_D0 DDR3_P1_E0 DDR3_P0_C1 DDR3_P1_F0 R-DIMM DDR3_P1_F1 Single-Rank Single-Rank Single-Rank Dual-Rank Dual-Rank Dual-Rank Quad-Rank Quad-Rank Quad-Rank Due to CPU limitation, read the following guidelines before installing the memory in Dual or 3 Channel mode Dual Channel-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 modules, it is recommended that memory of th same capacity, brand, speed, and chips be used. When enabling Dual Channel mode with two memory modules, be sure to install them in the DDR3_P0_C0 and DDR3_P0_C1 sockets for primary CPU; install DDR3_P1_F0 and DDR3_P1_F1 for secondary CPU. 3 Channel-1. 3 Channel mode cannot be enabled if only one or two DDR3 memory modules are installed. 2. When enabling 3 Channel mode with three, four or six modules, it is recommended that memory of the same capacity, brand, speed, and chips be used. When enabling 3 Channel mode with three - 19 - Hardware Installation
