What this kit is and who it fits

This 16GB kit contains two 8GB DDR3 1866 ECC registered DIMMs built for the Apple Mac Pro Late 2013 cylinder. It matches the factory memory specification for model MacPro6,1 and order numbers ME253LL/A, MD878LL/A, MQGG2LL/A and BTO or CTO configurations. The modules run at 1.50V and use major-brand chips tested to PC3-14900 speed.

What to verify before ordering

Confirm your Mac Pro is the Late 2013 cylinder model with model identifier MacPro6,1 and EMC 2630. The system must accept DDR3 1866 registered ECC memory in a 240-pin RDIMM form factor. Check that the installed processors are among the listed Xeon E5-1620v2, E5-1650v2, E5-1680v2 or E5-2697v2 variants to ensure full compatibility.

Who this suits and who should look elsewhere

This upgrade suits owners of the Late 2013 Mac Pro cylinder who need 16GB of ECC registered memory at the exact factory speed and voltage. It does not suit builders using any other Mac model, standard desktop motherboards or laptops that require unbuffered non-ECC DDR3 or a different DDR generation. Buyers who need larger capacities per module or a different pin count should look elsewhere.
