Capacity and Compatibility

This 32GB DDR5 module is built as a direct replacement for Micron part MTC20F2085S1RC48BA1. It targets server and workstation systems that require registered ECC memory for data integrity under heavy workloads.

Registered ECC and Voltage

The module operates at 1.1V with CL40 latency and a 2Rx8 organization. Registered buffering and on-die ECC reduce electrical load on the memory controller and correct single-bit errors without user intervention.

Installation Notes

The 288-pin DIMM fits standard DDR5 server slots; the 262-pin reference in the data sheet appears to be a documentation error. Verify that your platform supports DDR5 RDIMMs at 4800 speed and the registered signal format before ordering.

Questions about this item

Will the 32 GB DDR5 ECC RDIMM need any firmware updates or component swaps over its service life?

The module ships as a finished 32 GB DDR5 4800 CL40 registered DIMM; no firmware updates or field-replaceable parts are required once it is seated in a compatible 288-pin slot.

What limit appears first when the Micron 2Rx8 chipset runs at 4800 MT/s continuously?

Sustained operation is bounded by the JEDEC 1.10 V voltage ceiling and the CL40 latency window; thermal throttling or bandwidth saturation will trigger before any other electrical limit.

How much heat and noise does the 288-pin DDR5 RDIMM produce in a server chassis running all day?

The 1.10 V DDR5 module generates only modest heat with no moving parts, so acoustic output is effectively zero; a standard server airflow path is sufficient to keep temperatures in spec.
