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 Four Channel Memory Configuration This motherboard provides sixteen DDR3 memory sockets and supports Four Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Four Channel memory mode will be four times of the original memory bandwidth. The four DDR3 memory sockets are divided into four channels each channel has two memory sockets as following: Channel 1: DDR3_P0_A0/DDR3_P0_A1 (For pimary CPU); DDR3_P1_E0/DDR3_P1_E1 (For secondary CPU) Channel 2: DDR3_P0_B0/DDR3_P0_B1 (For pimary CPU); DDR3_P1_F0/DDR3_P1_F1 (For secondary CPU) Channel 3: DDR3_P0_C0/DDR3_P0_C1 (For pimary CPU); DDR3_P1_G0/ DDR3_P1_G1 (For secondary CPU) Channel 4: DDR3_P0_D0/DDR3_P0_D1 (For pimary CPU); DDR3_P1_H0/DDR3_P1_H1 (For secondary CPU) DDR3_P0_C0 DDR3_P0_C1 DDR3_P0_D0 DDR3_P0_D1 DDR3_P0_B1 DDR3_P0_B0 DDR3_P0_A1 DDR3_P0_A0 DDR3_P1_E0 DDR3_P1_E1 DDR3_P1_F0 DDR3_P1_F1 DDR3_P1_H1 DDR3_P1_H0 DDR3_P1_G1 DDR3_P1_G0 Due to CPU limitations, read the following guidelines before installing the memory in Four Channel mode. 1. Four Channel mode cannot be enabled if only one DDR3 memory module is installed. 2. When enabling Four 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.
