Targeted Mac Pro upgrade

This 8 GB kit contains two 4 GB DDR3 1333 MHz ECC UDIMM modules built for Apple Mac Pro towers from Mid 2010 and Mid 2012 with 6-Core or 12-Core Xeon processors. It matches the MD771LL/A and MacPro5,1 specifications exactly.

Standard voltage operation

The modules run at 1.50 V and use unbuffered ECC chips on a major-brand chipset. No extra cooling or power delivery is required beyond what the Mac Pro memory bays already provide.

Dual-channel population

Installing the pair fills two slots for dual-channel bandwidth while leaving remaining bays free for further expansion. The 240-pin form factor ensures a direct fit in the approved A1289 systems without adapters.

Questions sur cet article

How do I install the 240-pin DDR3 ECC UDIMM modules in a Mac Pro 5,1, and what step do people often miss?

Power down, unplug, open the side panel, remove the memory tray, insert each 4 GB module into the slots matching the 1333 MHz speed until the ejectors click, then reseat the tray before closing the case; the step often missed is fully seating both ejector clips on every module.

What maintenance or replacement will this 1.50 V DDR3 ECC kit need over its lifetime?

No scheduled maintenance is required; the modules are solid-state and covered by a lifetime warranty, so replacement only occurs if a stick fails or you later upgrade to higher-capacity DDR3 ECC UDIMMs.

What limit appears first when the Mac Pro runs sustained workloads with this 1333 MHz PC3-10600 memory?

The memory bandwidth ceiling of 1333 MHz DDR3 is reached before CPU or thermal limits, capping throughput for long renders or large datasets on the supported Xeon processors.
