Sample Memory Configurations; Removing Memory Modules - Dell NX430 Owner's Manual

The installation guidelines for memory modules are as follows:
• Memory modules must be identical in size, speed, and technology.
• 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.
