- Rotate both DIMM socket ejectors outward as far as they will go.
The DIMM is partially ejected from the socket (See DIMM Socket Release and Alignment).
- Carefully lift the DIMM straight up to remove it from the socket.

(quad rank, dual rank, or single rank) or leave the socket empty.
Note - DIMM filler panels are optional and not required.
