5.3. RAM Installation
This motherboard supports DDR5 memory in a dual-channel configuration. Open the clips on both ends of the DIMM slots. Align the notch on the DDR5 memory module with the key in the slot. Press down firmly on both ends of the memory module until the clips snap into place.
Figure 7: Examples of DDR5 RAM modules and their timing specifications.
5.4. M.2 SSD Installation
The motherboard features two M.2 slots for NVMe SSDs. Locate the M.2 slot(s) and remove the standoff screw. Insert the M.2 SSD at an angle into the slot, then gently push it down and secure it with the standoff screw. Ensure the M.2 heatsink (if provided) is properly installed for optimal thermal performance.
