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 Triple Channel Memory Configuration
The system provides 24 DDR4 memory sockets for per CPU and supports Triple Channel Technology. When
the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory.
Enabling Triple Channel memory mode will be triple of the original memory bandwidth.
The twenty-four DDR4 memory sockets are divided into three channels each channel has two memory
sockets as following:
Channel 1: DIMM_P0_A0/DIMM_P0_A1/DIMM_P0_A2 (For pimary CPU);
DIMM_P1_E0/DIMM_P1_E1/DIMM_P1_E2 (For secondary CPU)
Channel 2: DIMM_P0_B0/DIMM_P0_B1/DIMM_P0_B2 (For pimary CPU);
DIMM_P1_F0/DIMM_P1_F1/DIMM_P1_F (For secondary CPU)
Channel 3: DIMM_P0_C0/DIMM_P0_C1/DIMM_P0_C2 (For pimary CPU);
DIMM_P1_G0/DIMM_P1_G1/DIMM_P1_G2 (For secondary CPU)
Channel 4: DIMM_P0_D0/DIMM_P0_D1/DIMM_P0_D2 (For pimary CPU);
DIMM_P1_H0/DIMM_P1_H1/DIMM_P1_H2 (For secondary CPU)
