seated in the socket. The side clips will automatically lock the module into

Memory Installation Guidelines
When installing memory modules, the DIMM slots should be populated in the
following order: DIMMA1, DIMMB1, then DIMMA2, DIMMB2.
• Always use DDR4 DIMM modules of the same size, type and speed. Mixing
memory modules of different types and speeds is not allowed.
• The motherboard will support one DIMM module installed. However, for best
memory performance, install DIMM modules in pairs.
Installing DIMM Memory Modules
1. Align the key on the bottom of the DIMM module against the key on the
memory slot. Take note of the notches on the side of the DIMM module, and
of the locking clips on the socket to avoid causing damage.
