64GB DDR5 ECC Registered memory for a verified server upgrade

64GBDDR5 5600MT/sECC Registered2Rx4 CL46

The Micron MTC40F2046S1RC56BR is a single 64GB DDR5 ECC Registered DIMM specified at 5600MT/s, CL46 and 1.1V. Its dual-rank 2Rx4 organisation and 288-pin RDIMM format target compatible server and workstation platforms. Select it by the complete part number and the system memory qualification rules, rather than by DDR5 capacity alone.

Best For: IT teams expanding memory in a server whose manufacturer or Micron compatibility list specifies this exact part.
Before you order: Verify the exact server or workstation, processor, firmware and slot population rules before ordering. This is registered ECC memory, not desktop UDIMM or laptop SO-DIMM. Actual speed follows the supported platform and installed memory configuration. If your organisation requires a fixed DRAM die qualification, confirm the delivered design instead of assuming a die revision from this retail part number.

What's in the Box

  • One 64GB Micron MTC40F2046S1RC56BR memory module.

What It Means in Practice

  • 64GB is the capacity of this single module; plan the total upgrade around existing memory and available slots.
  • Follow the server service manual for approved slot placement and supported module combinations.
  • Shut the system down and follow its maintenance and antistatic procedures during installation.

What Will Not Work

  • Do not select this registered module for a desktop or laptop solely because it uses DDR5.
  • 5600MT/s is the module specification, not a promise that every supported server configuration will run at that rate.
  • A matching pin count alone does not prove compatibility.

Frequently Asked Questions

Is this ordinary desktop DDR5 memory?
No. It is ECC Registered DIMM memory for systems that explicitly support this memory class and part.
Will it run at 5600MT/s in every server?
The module is specified at 5600MT/s. The actual operating rate depends on the server, processor and memory population.
What does 2Rx4 mean?
It identifies two ranks with x4 DRAM organisation. Match it to the exact system support and memory population rules.
Is this a multi-module kit?
This listing is for one 64GB module. Confirm the number of modules required by your upgrade plan.
Singular Expert Insight

Start with the server’s compatibility list and population guide, then select the module. Capacity, generation and pin count are useful checks, but registered-memory support and the exact platform configuration decide whether the upgrade is suitable.

Buyer’s Guide

✓ Buy it if Your exact server configuration supports MTC40F2046S1RC56BR and you need an additional 64GB ECC RDIMM.
✕ Skip it if Your system requires unbuffered desktop memory or laptop SO-DIMMs, or compatibility has not been established.
→ Also consider The server’s approved memory population plan and whether matched modules are needed for the intended configuration.
