NOTE:
MT/s indicates DIMM speed in Mega-Transfers per second.
The system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipset
architectural configuration. The following are the recommended guidelines for installing memory modules:
● All DIMMs must be DDR4.
● If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module.
● Populate memory module sockets only if a processor is installed.
○ For single-processor systems, sockets A1 to A4 is available.
● In Optimizer Mode, the DRAM controllers operate independently in the 64-bit mode and provide optimized memory
performance.
NOTE:
DIMM speed is limited to 2933 MT/s when mixing dual rank DIMMs with single rank or dual rank DIMMs in the
same channel.

● Populate all the sockets with white release tabs first, followed by the black release tabs.
● Unbalanced or odd memory configuration results in a performance loss and system may not identify the memory modules
being installed, so always populate memory channels identically with equal DIMMs for best performance.
Removing a memory module
Prerequisites
1. Follow the safety guidelines listed in the
2. Follow the procedure listed in the
WARNING:
The memory modules are hot to touch for some time after the system has been powered off. Allow
the memory modules to cool before handling them.
Steps
1. Locate the appropriate memory module socket.
2. To release the memory module from the socket, simultaneously press the ejectors on both ends of the memory module
socket to fully open.
CAUTION:
Handle each memory module only by the card edges, ensuring not to touch the middle of the
memory module or metallic contacts.
3. Lift the memory module away from the system.
