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.)
