Installation Of Memory Modules (So-Dimm) - ASROCK 4X4-R1000M User Manual

2.3 Installation of Memory Modules (SO-DIMM)

4X4-R1000M / 4X4-R1000V / 4X4-V1000M provides two 204-pin DDR4 (Double
Data Rate 4) SO-DIMM slots.
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM
matches the break on the slot.
1. The SO-DIMM only fits in one correct orientation. It will cause permanent damage
to the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at
incorrect orientation.
2. Please do not intermix different voltage SO-DIMMs on this motherboard.
Step 2. Firmly insert the SO-DIMM into the slot until the retaining clips at both
ends fully snap back in place and the SO-DIMM is properly seated.
