Lenovo ThinkSystem 64GB DDR4 3200MT/s 2Rx4 RDIMM-A Performance+

Sixty-four gigabytes per module puts the Lenovo ThinkSystem 4X77A12189 at the heavier end of registered DDR4. It is a 2Rx4 RDIMM-A running DDR4 3200MT/s at 1.2V with ECC, marked Performance+.

The named system is the Lenovo ThinkSystem SR665, and the feature code is BCZZ. If your build sheet uses the feature code, it points to this module. Compare it with the 32GB 2Rx8 module from the same family when you size memory: the larger one halves the slot count needed for a given total.

A high-capacity module like this suits memory-hungry virtual machines and in-memory databases on the SR665.
