32GB DDR4 ECC LRDIMM server memory

This 32GB DDR4 module runs at 2133MHz with CL15 latency and operates at 1.20V. It uses a 288-pin DIMM form factor and is built with Micron chipset components. The module is a direct replacement for Micron MTA72ASS4G72LZ-2G1A1HG and MTA72ASS4G72LZ-2G1A1IG part numbers.

Load Reduced 4Rx4 architecture for high-density

The single specification that determines fit is the 4Rx4 Load Reduced DIMM organisation. This rank and buffer configuration must match the server memory controller requirements exactly; standard RDIMM or UDIMM modules will not work in the same slots.

Low-voltage operation at 1.2V reduces heat output

Running at the standard DDR4 voltage of 1.20V keeps power draw and thermal load low during normal server workloads. The Load Reduced buffer design minimises electrical loading on the memory bus, contributing to stable operation without active cooling on the module itself.

Questions about this item

Will the 2133 MHz speed actually run at that rate once installed in a server?

The module is rated for DDR4 2133 MHz (PC4-17000). It will operate at that speed provided the platform supports DDR4-2133; otherwise the memory controller will downclock it to the highest supported frequency.

What does the LRDIMM 4Rx4 designation mean for the memory controller?

LRDIMM (Load Reduced DIMM) with 4Rx4 organisation uses a buffer to reduce electrical load on the memory bus, allowing higher capacities per channel while presenting only a single logical rank to the controller.

Does the 288-pin DIMM fit every DDR4 server slot?

This module uses the standard DDR4 288-pin DIMM form factor. It fits any server or workstation slot wired for DDR4 LRDIMM; verify your system’s qualified-vendor list for 4Rx4 LRDIMM support before installing.
