Mac Pro Late 2013 Memory Kit

This 24GB kit contains three 8GB DDR3 1866/1867MHz ECC Registered DIMMs built for the Mac Pro (Late 2013, Cylinder). It matches Apple model IDs MacPro6,1 and order numbers ME253LL/A, MD878LL/A, MQGG2LL/A. The modules run at 1.50V and use major brand chips. They are designed for owners who need to expand the memory capacity of this specific workstation.

Sustained Workload Behaviour

ECC Registered operation detects and corrects single-bit errors during long rendering, virtualisation or scientific sessions. Registered buffering reduces electrical load on the memory controller when all three slots are populated. The 1866/1867MHz speed maintains consistent throughput under continuous multi-threaded demand. This configuration supports the 2.7GHz, 3.0GHz, 3.5GHz and 3.7GHz Xeon processors listed for the platform.

DDR3 RDIMM Form Factor Constraint

The 240-pin DDR3 RDIMM form factor fits only systems that accept registered ECC DDR3 modules. It will not work in consumer desktops, laptops or any platform requiring unbuffered UDIMMs or a different DDR generation. Buyers who need a different pin count, voltage or memory type must select another product.

商品問答

How much power does the 24GB DDR3 1866 ECC RDIMM kit draw at its rated 1.50V?

Each module operates at 1.50V, the standard voltage for DDR3 1866 ECC RDIMMs, keeping power draw consistent with Apple's original specification for the Mac Pro (Late 2013).

Does the Mac Pro (Late 2013) need any firmware update or specific CPU to recognise these 3x8GB ECC RDIMMs?

The kit is validated for MacPro6,1 (EMC 2630) with Xeon E5-1620v2, E5-1650v2, E5-1680v2 or E5-2697v2 processors; no extra firmware step is required beyond the standard macOS version that shipped with those CPUs.

Can I keep my existing Apple DDR3 1866 ECC RDIMMs and add this 24GB kit to fill all four slots?

Yes, the modules match Apple's DDR3 1866/1867MHz PC3-14900 ECC RDIMM specification exactly, so they will run alongside the factory memory at the same speed and timings.
