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 memory support list.) • 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 Channel Memory Configuration This motherboard provides four DDR3 memory sockets and supports Dual 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 0: DDR3_1, DDR3_3 Channel 1: DDR3_2, DDR3_4 Dual Channel Memory Configurations Table DDR3_1 DDR3_2 DDR3_3 DDR3_4 Two Modules DS/SS DS/SS - - - - - - - - DS/SS DS/SS Four Modules DS/SS DS/SS DS/SS DS/SS (SS=Single-Sided, DS=Double-Sided, "- -"=No Memory) If two memory modules are to be installed, it is recommended that you install them in the DDR3_1 and DDR3_2 sockets. DDR3_1 DDR3_2 DDR3_3 DDR3_4 Due to CPU limitation, 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 and installed in the same colored DDR3 sockets for optimum performance.
