- Locate the four DDR4 DIMM slots.
- Open the clips at both ends of the DIMM slot.
- Align the memory module with the slot, ensuring the notch on the module matches the key in the slot.
- Press down firmly on both ends of the memory module until the clips snap into place.
4.4. Expansion Card Installation
- Identify the desired PCI Express slot (1x PCI-E 3.0 x16, 2x PCI-E 3.0 x8).
- Remove the corresponding metal slot cover from your chassis.
- Align the expansion card with the slot and press down firmly until it is securely seated.
- Secure the card with a screw or retention clip.
