Overview

High capacity per slot is the point of the Kingston Server Premier KSM64R52BD4-128MB. Each module holds 128GB of DDR5 running at 6400 MT/s (PC5-6400), so a server or workstation can reach a large memory total with fewer DIMMs.

The module is a 288-pin RDIMM with a 2Rx4 rank layout and a 16G x 80-bit (EC8) organization. It carries ECC at the module level as well as on-die ECC inside the DDR5 chips. DRAM is Micron B-die.

Timings are 52-52-52 at CL52, and the operating voltage is 1.1 V. The rated operating temperature range is 0 to 95 °C.

This is a registered module. Use it in boards that take DDR5 RDIMMs, and keep speed and rank consistent across a channel when you add it to an existing population.
