Mac Pro 2013 DDR3 ECC RDIMM

This 16 GB DDR3 1866 module is built specifically for the 2013 Apple Mac Pro. It carries ECC and registered buffering for data integrity in workstation workloads. The single-rank 2Rx4 organisation matches the factory memory architecture. Buyers needing non-ECC or unbuffered DIMMs should look elsewhere.

Sustained workstation throughput

Registered buffering and ECC correction keep error rates low during long rendering or compute sessions. The CL13 latency and 1.35 V operation stay within the Mac Pro thermal envelope. No heat spreader is fitted, relying on the system’s directed airflow. Systems without registered DIMM support cannot use this module.

Slot-in installation caveats

The 288-pin RDIMM seats vertically in the Mac Pro’s user-accessible memory tray; no tools are required. Verify the firmware revision before installing, as early revisions may not recognise 16 GB densities. Mixing with non-registered or non-ECC modules will prevent boot. The package contains one 16 GB stick only.

Questions about this item

Does the 1.35 V DDR3 1866 module run cooler than standard 1.5 V memory in a Mac Pro 2013?

The module operates at 1.35 V, lower than the 1.5 V JEDEC baseline, so it draws less power and generates less heat during continuous workloads.

What slot type must the Mac Pro 2013 provide for this 288-pin RDIMM to be recognised?

The Mac Pro 2013 uses 204-pin DDR3 SODIMM slots, so this 288-pin RDIMM will not fit; the correct form factor for that system is SODIMM, not RDIMM.

Can this CL13 registered ECC stick work alongside the original Apple DDR3 1866 ECC UDIMMs already installed?

No, registered RDIMMs and unbuffered UDIMMs cannot be mixed on the same memory controller; all slots must use the same buffer type for the system to boot.
