About memory
You can add memory—dynamic random-access memory (DRAM) or video
random-access memory (VRAM)—to your computer in packages called Dual
Inline Memory Modules, or DIMMs. You can also upgrade your computer’s
cache by installing a cache module.
The following illustration shows the locations of memory slots on the logic
board. See the sections that follow for important information about DRAM,
VRAM, and cache configurations.

*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.)
