Green rectangular DDR5 RDIMM module with gold contacts and black chips in tray packaging

Micron Technology, Inc.

Micron Technology, Inc. MTC40F2046S1RC64BH1T 64GB DDR5 RDIMM 6400 CL52 2Rx4 server RAM

SKU CH-NAF9-AXR5H MPN MTC40F2046S1RC64BH1T

64 GB DDR5 RDIMM running at 6400 MHz with CL52 latency and 2Rx4 organisation for high-density server memory

  • 64 GB capacity supports memory-intensive server workloads
  • DDR5 architecture delivers 6400 MHz data rates for high throughput
  • Registered DIMM design improves signal integrity on multi-slot channels
  • CL52 latency timing balances speed with stability at rated frequency
  • 2Rx4 dual-rank organisation increases density per module slot

64GB DDR5 RDIMM for servers

Micron MTC40F2046S1RC64BH1T is a 64GB DDR5 RDIMM rated at 6400 MHz with CL52 latency. The 2Rx4 organisation uses 16Gbit density to reach this capacity in a single module. It targets server platforms that require registered memory and can operate at the stated data rate.

Capacity and headroom at 64GB

A single 64GB module provides substantial memory per slot, allowing dense configurations in multi-channel server boards. Workloads such as virtualisation, in-memory databases or large-scale analytics benefit from the available capacity. The module runs out of headroom when the platform demands more memory than the installed DIMM count can supply.

Tray packaging and registered design

The tray pack delivers the module without retail packaging, suited for system integrators and bulk deployment. Registered buffering reduces electrical load on the memory controller, enabling stable operation in populated channels. No additional accessories or software are included with this component.

商品問答

Will this 6400 MHz DDR5 RDIMM run at its rated speed in a server platform that only supports lower DDR5 speeds?

The module is rated for 6400 MHz operation with CL52 latency; actual speed will be negotiated with the platform's memory controller and may run at a lower supported frequency if the server does not qualify 6400 MHz.

How can I confirm the 2Rx4 organisation and CL52 timing are active after installation?

Check the server BIOS or a tool such as dmidecode or CPU-Z; they will report the module as 64 GB DDR5 RDIMM, 2Rx4 organisation, 6400 MT/s data rate and CL52 CAS latency.

Does the tray packaging include any heatsinks, cables or mounting hardware, or just the memory module?

The tray contains only the 64 GB DDR5 RDIMM module itself; no heatsinks, cables or additional mounting hardware are supplied.
