1-4-1 Dual Channel Memory Conguration
This motherboard provides four DDR3 memory sockets and supports Dual Channel Technology. After the
memory is installed, the BIOS will automatically detect the specications 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_4, DDR3_2
Channel B: DDR3_3, DDR3_1
DDR3_4 DDR3_2 DDR3_3 DDR3_1
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.1.
When enabling Dual Channel mode with two or four memory modules, it is recommended that memory2.
of the same capacity, brand, speed, and chips be used and installed in the same colored DDR3
sockets. For optimum performance, when enabling Dual Channel mode with two memory modules,
we recommend that you install them in the DDR3_1 and DDR3_2 sockets.
