Mac Pro Late 2013 24GB kit

This 24GB kit (3 x 8GB) of DDR3 1866 ECC UDIMM memory is built for the Apple Mac Pro (Late 2013, Cylinder) with model ID MacPro6,1. It matches the factory specification of 1.50V unbuffered ECC modules on a 240-pin interface. The three-module layout fills three of the four available slots for a balanced upgrade.

Ideal for cylinder Mac Pro owners

The kit suits owners of ME253LL/A, MD878LL/A, MQGG2LL/A or BTO/CTO configurations who need 24GB of validated ECC memory. Systems that require registered DIMMs, a different pin count, or non-ECC modules cannot use this kit. Buyers with other Mac models or non-Apple workstations should verify their exact memory requirements before purchasing.

DDR3 1866 ECC UDIMM 240-pin

The decisive specification is the DDR3 1866 (PC3-14900) ECC UDIMM 240-pin form factor at 1.50V. Only Mac Pro (Late 2013) systems that accept unbuffered ECC UDIMMs at this speed and voltage will recognise and run the memory correctly.

Questions about this item

Will the 1866 MHz modules run with the 1867 MHz speed the Mac Pro Late 2013 expects?

Yes, the kit is rated DDR3 1866/1867 MHz PC3-14900 to match the cylinder Mac Pro memory bus.

How can I confirm the ECC UDIMM modules are recognised after installation?

Open About This Mac or System Report; total memory should show 24 GB and the memory slot details will list ECC UDIMM for each 8 GB module.

Does the box contain only the three 8 GB sticks or are tools or heat spreaders included?

The kit supplies three 8 GB DDR3 ECC UDIMM modules; no heat spreaders or installation tools are provided.
