5 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.
2-5-1 Four Channel Memory Configuration
The system provides sixteen DDR4 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 DDR4 memory sockets are divided into four channels each channel has two memory sockets as
following:
Channel 1: DIMM_P0_A0/DIMM_P0_A1 (For pimary CPU)/
DIMM_P1_E0/DIMM_P1_E1 (For secondary CPU)
Channel 2: DIMM_P0_B0/DIMM_P0_B1 (For pimary CPU)
DIMM_P1_F0/DIMM_P1_F1 (For secondary CPU)
Channel 3: DIMM_P0_C0/DIMM_P0_C1 (For pimary CPU)
DIMM_P1_G0/DIMM_P1_G1 (For secondary CPU)
Channel 4: DIMM_P0_D0/DIMM_P0_D1 (For pimary CPU)
DIMM_P1_H0/DIMM_P1_H1 (For secondary CPU)
