Designed for Mac Pro (Late 2013) cylinder

This 16GB kit contains two 8GB DDR3 ECC UDIMM modules that run at 1866/1867MHz PC3-14900 and 1.50V. It matches Apple order numbers ME253LL/A, MD878LL/A, MQGG2LL/A and model ID MacPro6,1 (A1481 EMC 2630).

Suits owners of the Late 2013 Mac Pro who need ECC

Builders who need registered DIMMs, non-ECC modules, a different pin count, or a memory generation other than DDR3 cannot use this kit. It is validated only for the cylinder Mac Pro with the listed Xeon processors.

240-pin DDR3 ECC UDIMM form factor decides fit

The modules are unbuffered ECC UDIMMs on a 240-pin interface at 1.50V. If your system requires a different form factor, voltage, or ECC type, this memory will not install or function.

商品問答

How do I install the 240-pin DDR3 ECC UDIMM modules in the Mac Pro Late 2013, and which step is commonly missed?

Power down, open the side panel, release the memory tray latch, insert each 8 GB module firmly until the ejectors click, then reseat the tray and close the case; the step often missed is fully seating both modules before locking the tray back in place.

What maintenance or replacement will this 16 GB DDR3 1866 MHz ECC kit need over time?

No routine maintenance is required; the modules are solid-state and covered by a lifetime warranty, so replacement would only be necessary if a module fails or you later upgrade to a higher capacity.

What is the first limit that appears under sustained heavy workloads with this 1.50 V DDR3 1866 MHz memory?

The memory controller on the supported Xeon E5-1620 v2, E5-1650 v2, E5-1680 v2 and E5-2697 v2 CPUs caps the data rate at 1866 MHz, so bandwidth ceiling is reached before thermal or voltage limits.
