64 GB DDR5 ECC RDIMM for servers

This 64 GB DDR5 4800 CL40 registered DIMM targets IT professionals and system integrators who need reliable ECC memory for enterprise workloads. The single-module design simplifies capacity scaling in multi-slot server boards.

Micron-compatible part number MR38400-924

The module is validated against Micron MTC40F2046S1RC48BA1 and built with major OEM chips from Samsung, Micron or Hynix. Rigorous stress testing under load aims to ensure stability in mission-critical environments.

Suits DDR5 RDIMM platforms needing 2Rx4 density

Buyers whose systems require unbuffered UDIMM, non-ECC memory or lower-voltage 1.1 V modules with different rank organisation should look at something else. Compatibility depends on the motherboard qualified-vendor list.

Questions about this item

Will the 2Rx4 DDR5 RDIMM require any firmware updates or component replacements during its service life?

The module has no heat spreader and uses standard 1.10V DDR5 operation; no firmware updates or component replacements are expected for the memory itself.

What limit appears first when the 64GB registered DIMM runs at 4800 MT/s continuously?

Sustained throughput is capped by the CL40 latency and the PC5-38400 data rate; the memory controller reaches its bandwidth ceiling before the DRAM chips do.

How much heat and power does the 1.10V 288-pin ECC RDIMM produce under all-day load?

At 1.10V the module draws minimal power and runs cool without a heat spreader; typical server airflow keeps temperatures well within spec.
