Sample Memory Configurations - Dell EMC PowerEdge R620 Owner's Manual

• Memory modules installed in memory module sockets with white release levers must be identical and the same rule applies for sockets
with black and green release tabs. This ensures that identical memory modules are installed in matched pairs—for example, A1 with A2,
A3 with A4, A5 with A6, and so on.
