8GB DDR3 ECC module for Mac Pro 2013

This 8 GB DDR3 1866 MHz ECC UDIMM is built specifically for the Apple Mac Pro Late 2013 cylinder. It uses a 240-pin unbuffered design with major-brand chips and runs at 1.50 V. The single module adds error-correcting memory to compatible Xeon workstations.

Suits owners of MacPro6,1 needing ECC reliability

Buyers who want non-ECC memory or a different DDR generation cannot use this module. Systems outside the listed Apple order numbers ME253LL/A, MD878LL/A, MQGG2LL/A and model ID MacPro6,1 are not supported. The part does not fit standard PC motherboards.

Fits the Mac Pro four-slot memory tray

The UDIMM installs directly into the 240-pin slots without adapters. ECC operation depends on the installed Xeon processor supporting the feature. No heat spreader is included, so airflow in the Mac Pro chassis handles cooling. The module leaves the remaining three slots free for further expansion.

Questions sur cet article

My Mac Pro (Late 2013) currently has four 4 GB modules installed — will this 8 GB DDR3 1866 ECC UDIMM fit in the remaining slot?

Yes, the module uses the 240-pin ECC UDIMM form factor required by the Mac Pro (Late 2013) and runs at 1.50 V, so it will seat in any free slot.

If I keep the original 1866 MHz memory and add this stick, will the system still run at 1866 MHz?

The module is rated for DDR3 1866/1867 MHz (PC3-14900); when mixed with identical-speed sticks the Mac Pro will continue to operate at 1866 MHz.

After installing the module, how can I confirm the Mac recognises the full 8 GB with ECC active?

Open About This Mac → System Report → Memory; you should see an 8 GB DDR3 ECC UDIMM entry at 1867 MHz with ECC status shown as enabled.
