64GB DDR5 4800 ECC RDIMM

This 64GB DDR5 4800 registered DIMM brings error-correcting, buffered memory to compatible Micron-based servers and workstations. It runs at PC5-38400 with CL40 latency and a 1.10V operating voltage. The 2Rx4 organisation and 288-pin form factor match the Micron MTC40F2046S1RC48B specification.

Replaces lower-capacity or non-ECC DDR5 modules

Swapping out smaller unbuffered sticks for this 64GB registered unit adds both capacity and data-integrity protection in a single step. The upgrade is worthwhile when the platform supports registered ECC memory and the workload demands sustained throughput with error detection.

Handles large datasets and virtualised workloads

The 64GB density provides headroom for memory-intensive databases, virtualisation hosts and compute clusters. Systems limited to fewer DIMM slots or lower maximum registered capacity will reach their ceiling before this module does.

Questions about this item

Does the 288-pin DDR5 RDIMM module fit a standard DDR5 server DIMM slot?

Yes, the 288-pin DDR5 RDIMM form factor matches the standard DDR5 registered DIMM slot used in compatible Micron server and workstation platforms.

What is the correct seating procedure for this registered ECC module?

Align the module notch with the slot key, press down firmly until both side latches click audibly, ensuring the registered buffer makes full contact.

Will the 2Rx4 rank organisation require a firmware update later?

The 2Rx4 configuration is a fixed hardware attribute; no firmware update can change it, though a BIOS update may improve compatibility with the registered ECC design.
