96GB DDR5 6400 ECC RDIMM Server Module

This 96GB DDR5 6400 ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It operates at PC5-51200 speed with a CAS latency of 32 and runs at the standard 1.10V DDR5 voltage. The 2Rx4 dual-rank organisation uses Micron DRAM ICs on a 288-pin registered DIMM without a heat spreader.

Who this suits and who should look elsewhere

This module suits administrators upgrading or repairing systems qualified for the Micron MTC40F204WS1RC64BB2 or MTC40F204WS1RC64BC1 part numbers. It is not for desktop PCs or laptops that accept only unbuffered non-ECC UDIMMs. Buyers who need a lower-capacity stick or a different speed grade should select a module matched to their platform's qualified vendor list.

Registered ECC DDR5 at 6400 MT/s decides fit

The single specification that determines compatibility is the registered ECC DDR5 6400 MT/s RDIMM form factor with 2Rx4 ranking. Only platforms that explicitly support registered ECC DDR5 at this data rate and rank configuration will accept this module. Verify the system manual or QVL before purchase.

Questions about this item

My server needs DDR5 6400 RDIMMs — does this module match that exact speed and pin count?

Yes, it is a 288-pin DDR5 6400 RDIMM rated at PC5-51200 with CL32 latency.

I plan to keep some 32GB DDR5 RDIMMs in the same chassis — will the 2Rx4 rank on this 96GB stick cause any conflict?

Mixed capacities and ranks are supported by the platform's memory controller; follow the system manual for correct channel population rules.

After seating the module, how can I confirm it is running at 6400MHz with ECC active?

Check the BIOS memory information screen or run a tool like dmidecode — it should report 6400 MT/s, ECC enabled, and 96GB capacity.
