•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
DualChannelMemoryConfigurationsTable
(SS=Single-Sided, DS=Double-Sided, "- -"=No Memory)
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.
