16GB DDR3 ECC kit for Mac Pro

This 16GB kit contains four 4GB DDR3 1333 ECC UDIMM modules built for Apple Mac Pro Mid 2010 and Mid 2012 towers. The modules run at 1.50V and use a 240-pin form factor with unbuffered ECC. They are designed to match the memory specifications required by MacPro5,1 systems.

Suits owners of compatible Mac Pro towers

Buyers with Mac Pro models from Mid 2010 or Mid 2012 using 6-core or 12-core Xeon processors can use this kit to reach 16GB across four slots. It is not for Mac Pro models outside those years or configurations, nor for systems requiring registered or non-ECC memory.

Check your Mac Pro model and slot count

Verify your system is a Mac Pro Mid 2010 or Mid 2012 with model ID MacPro5,1 and order numbers such as MD771LL/A. Confirm the machine accepts unbuffered ECC UDIMM modules and has four available memory slots for this 4x4GB configuration.

Questions about this item

What Mac Pro models and processor configurations must I already own for this 16GB DDR3 1333 ECC UDIMM kit to work?

This kit is validated for Mac Pro models A1289 (EMC 2314-2 and EMC 2629) with MacPro5,1 identifier and order number MD771LL/A, running Xeon CPUs including 2.4GHz E5645, 2.66GHz X5650, 3.06GHz X5675, 2.93GHz X5670 or 3.33GHz W3680.

Will the four 4GB modules occupy every slot on the memory riser, or can I keep existing sticks alongside them?

The kit provides four 240-pin UDIMMs totalling 16GB; the Mac Pro Mid 2010/2012 uses a quad-channel riser with four slots per riser, so installing this kit fills one complete riser.

How can I confirm the system recognises all 16GB at the correct 1333 MHz speed and ECC function after installation?

Open About This Mac or System Report; it should show 16GB total, DDR3 ECC, 1333 MHz speed and PC3-10600 rating for each of the four slots populated.
