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.

1-4-1 Four Channel Memory Configuration

This motherboard provides twenty-four 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/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_F2 (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)
When only one DIMM is used, it must be populated in memory slot0 first.
Memory populated sequence must be followed with slot0/slot1/slot2
System will not boot normally with incorrect populated sequence.
Due to CPU limitations, read the following guidelines before installing the memory in Four Channel mode.
1. Four Channel mode cannot be enabled if only one DDR4 memory module is installed.
2. When enabling Four 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.
