Targeted Mac Pro Upgrade

This 4 GB DDR3 1333 ECC UDIMM module is built for Apple Mac Pro towers from Mid 2010 and Mid 2012 with 6-Core or 12-Core Xeon processors. It matches the exact PC3-10600 specification required by MacPro5,1 systems identified as A1289. The single 240-pin DIMM installs directly into the available memory slots to increase total system capacity.

Build Integration

The unbuffered ECC design operates at the standard 1.50 V used by these Mac Pro models, requiring no voltage adjustment or firmware changes. Each module uses major-brand chips validated for Apple order numbers including MD771LL/A. Adding this stick frees the memory controller from paging pressure when running multiple professional applications simultaneously.

Sustained Workload Behaviour

ECC error correction detects and corrects single-bit errors in real time, preventing data corruption during long rendering or compute sessions. The 2Rx8 rank organisation maintains stable throughput across all populated channels under continuous load. Rigorous component testing ensures the modules maintain rated 1333 MHz speeds without throttling during extended operation.
