Installing Memory Modules (Dimm) - ASROCK IMB-A1000 User Manual

2.1 Installing Memory Modules (DIMM)

This motherboard provides two DDR4 (Double Data Rate 4) SO-DIMM
slots.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM
matches the break on the slot.
The DIMM only fits in one correct orientation. It will cause
permanent damage to the motherboard and the DIMM if you
force the DIMM into the slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both
ends fully snap back in place and the DIMM is properly seated.
