Introduction

This guide shows how to open up your Mac Pro to replace or install additional RAM modules. You can complete this procedure without using any tools.

Before you begin, be sure to purchase the correct RAM modules. The Mac Pro supports registered (R-DIMM) and Load-Reduced (LR-DIMM) RAM—but you cannot mix R-DIMMs and LR-DIMMs in a single computer. Apple installs R-DIMMs in Mac Pros configured with 192GB of RAM or less; setups with more than 192GB will have LR-DIMMs instead.

In addition, 8-core Mac Pros will come with 2666MHz (PC4-21300) RAM installed, while other models will have 2933 MHz (PC4-23400) RAM. You can install RAM modules with different clock ratings into the same Mac Pro. Click here for Apple’s RAM specifications.

Note: The Mac Pro only accepts RAM modules installed in specific amounts and configurations. For more details, check out Apple’s official guide.
