2-4-1 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 six DDR3 memory sockets are divided into three channels and each channel has two memory sockets
as following:
Channel A: DDR3_P0_A0, DDR3_P0_A1 (For pimary CPU)
DDR3_P1_D0, DDR3_P1_D1 (For secondary CPU)
Channel B: DDR3_P0_B0, DDR3_P0_B1(For pimary CPU)
DDR3_P1_E0, DDR3_P1_E1 (For secondary CPU)
Channel C: DDR3_P0_C0, DDR3_P0_C1(For pimary CPU)
DDR3_P1_F0, DDR3_P1_F1 (For secondary CPU)
2-4 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.
•
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.
Due to CPU limitations, 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 for optimum performance.
