Mac Pro 2013 32 GB DDR3 kit

This kit supplies 32 GB of DDR3 memory in two 16 GB modules built for the 2013 Mac Pro. Each stick runs at 1866 MHz with CL13 latency and includes ECC error correction plus registered buffering for data integrity.

DDR3 1866 MHz registered ECC limits

The DDR3 1866 standard tops out at this speed and voltage, so the system cannot run faster JEDEC profiles. Registered ECC modules add one clock cycle of latency and require a motherboard that supports registered DIMMs; they will not work in consumer boards that accept only unbuffered memory.

Installation in the 2013 Mac Pro

The 204-pin SODIMM form factor matches the Mac Pro memory slots, so modules seat without tools. Common issues are mixing registered ECC with unbuffered non-ECC sticks, which prevents boot, and failing to populate all four channels for full bandwidth.

Questions about this item

Should I pick the 32GB kit or a smaller capacity for my Mac Pro 2013?

The 32GB kit provides two 16GB modules, filling two slots and leaving room for further expansion up to the system maximum.

What does the 1866MHz speed deliver in actual use?

It runs at the Mac Pro 2013's native DDR3 1866 rate, matching the memory controller so bandwidth and latency stay at spec.

How does the 204-pin DDR3 SODIMM interface limit this kit?

The 204-pin SODIMM form factor fits only Mac Pro 2013 memory slots; it cannot be used in 288-pin RDIMM server boards.
