Installing and Removing Memory
The silkscreen on the board for the DIMMs displays DIMM_A3, DIMM_A2, DIMM_A1, DIMM_B3,
DIMM_B2, DIMM_B1 starting from the center of the board. DIMM A3 is the socket closest to the
processor socket. See chapter 2 – „Memory“ for a discussion of the memory requirements.

6. Make sure the clips at either end of the DIMM socket(s) are pushed outward to the open
position.
7. Holding the DIMM by the edges, remove it from its anti‑static package.
8. Position the DIMM above the socket. Align the small notch in the bottom edge of the DIMM
with the keys in the socket (see inset in Figure 12).
9. Insert the bottom edge of the DIMM into the socket.
10. When the DIMM is inserted, push down on the top edge of the DIMM until the retaining clips
snap into place. Make sure the clips are firmly in place.
