About memory
You can add dynamic random-access memory (DRAM) by installing Dual
Inline Memory Modules (DIMMs) in your computer.
The following illustration shows the locations of memory slots on the
logic board.
*When installing DRAM, for best performance, fill paired slots. (Slots are paired A1 and B1, then
A2 and B2, and so on. It doesn’t matter which pairs you use or the order in which you use them.)
