Mac Pro 2010/2012 ECC RDIMM Kit

This 24 GB kit contains three 8 GB DDR3 1333 MHz ECC registered DIMMs built for Mac Pro Mid 2010 and Mid 2012 towers. The modules run at 1.50 V and use a 240-pin RDIMM form factor with major-brand chips. They are designed to match Apple order numbers MD771LL/A and model identifier MacPro5,1.

Verify Mac Pro Model And Slot Availability

Confirm your machine is a Mac Pro Mid 2010 or Mid 2012 with a 6-core or 12-core Xeon processor such as the 2.4 GHz E5645 or 3.33 GHz W3680. The kit occupies three DIMM slots, so ensure at least three slots are free before ordering.

Suits Owners Of Compatible Mac Pro Towers

This memory suits users upgrading a qualified Mac Pro to 24 GB of ECC registered capacity. It is not for laptops, iMacs, Mac minis or any system that requires unbuffered non-ECC DDR3 or a different pin layout. Builders needing more than 24 GB or a different speed grade should look elsewhere.
