Step 1. Open the retaining clips on each end of the DIMM slot. Then, install the DIMM into the slot.
Attention: To avoid breaking the retaining clips or damaging the DIMM slots, open and close the

Step 2. Firmly press the DIMM straight down into the slot by applying pressure on both ends of the DIMM
simultaneously. The retaining clips snap into the locked position when the DIMM is firmly seated in

inserted; open the retaining clips, remove the DIMM, and then reinsert it.
