Mac Pro 2013 64GB DDR3 Kit

This 64GB kit contains four 16GB DDR3 1866 ECC RDIMM modules built for the Apple Mac Pro 2013. It delivers registered, error-correcting memory for workstations that require stability under sustained loads. The kit is new and tested for compatibility with that specific system.

Suited for Mac Pro 2013 owners adding 64GB

This kit suits owners of the 2013 Mac Pro who need 64GB of registered ECC memory in a matched four-module set. It is not for systems that use unbuffered SODIMMs, nor for builds that require 288-pin DIMMs, different voltages or non-ECC memory.

204-pin DDR3 SODIMM form factor decides fit

The modules use a 204-pin DDR3 SODIMM layout with registered ECC signalling at 1.35V and CL13 latency. Verify that your Mac Pro 2013 accepts registered 2Rx4 RDIMMs in this pin count before ordering, as other DDR3 systems use different pinouts or buffering.

Questions about this item

Does the DDR3 1866 PC3-14900 interface limit bandwidth on the Mac Pro 2013?

The kit runs at DDR3 1866 (PC3-14900) with CL13 latency, matching the Mac Pro 2013 memory controller specification.

What slot type and physical clearance do the 204-pin SODIMM modules need?

Each 16 GB module is a 204-pin DDR3 SODIMM without a heat spreader, fitting the four Mac Pro 2013 DIMM slots directly.

How are the four 2Rx4 registered ECC modules installed, and which step is often missed?

Insert all four 2Rx4 RDIMMs into the four slots until the latches click; the step often missed is populating every slot for quad-channel operation.
