48GB ECC UDIMM Kit for 12-Core Mac Pro

This 48GB kit contains six 8GB DDR3 1333 ECC UDIMM modules built for the Mac Pro 12-Core models from 2010 and 2012. It targets owners of those towers who need the full 48GB capacity across all six memory slots. The kit uses unbuffered ECC memory certified for Apple Mac systems.

DDR3 1333 PC3-10600 ECC Unbuffered

The decisive specification is DDR3 1333 PC3-10600 ECC unbuffered in a 240-pin UDIMM form factor. Only memory matching this exact speed, voltage, and ECC type will operate correctly in the specified Mac Pro models. Any other DDR generation or non-ECC module will not fit or function.

Fills all six slots in compatible towers

Installation occupies every memory slot in the Mac Pro 5,1 (A1289 EMC 2314-2 and 2629) with 2.4GHz, 2.66GHz, 2.93GHz, or 3.06GHz Xeon processors. The kit frees the builder from mixing modules and ensures matched timing across all channels. Systems needing registered or load-reduced DIMMs cannot use this product.
