16GB DDR5 ECC RDIMM for Servers

This 16GB A-Tech module is a registered DDR5 DIMM built with error-correcting code for server and workstation platforms. It operates at 4800 MT/s with CL40 latency at the standard 1.10V. The single-rank 1Rx8 organisation uses major-brand chips and matches the Samsung M321R2GA3BB6-CQK part number.

Who this suits and who it does not

This module suits administrators upgrading or repairing systems that require registered ECC DDR5 memory in a 288-pin form factor. It is not for desktop boards that accept only unbuffered non-ECC DIMMs. Buyers who need higher capacities per slot or different latency bins should verify their platform's qualified-vendor list before ordering.

The deciding specification

The registered ECC design is the single specification that determines compatibility; the memory controller must support registered DDR5 DIMMs with on-die ECC for this module to function.

Questions about this item

Will the registered DDR5 4800 RDIMM need any firmware updates or periodic re-seating during its service life?

The module is a standard registered DDR5 DIMM with no firmware; once seated in a 288-pin slot it requires no further maintenance beyond normal system cleaning.

What is the first limit reached when the 1Rx8 ECC RDIMM runs at full 4800 MHz continuously?

The CL40 latency at 1.10 V sets the timing boundary; sustained throughput is capped by the DDR5 4800 (PC5-38400) data rate.

How much heat and power does the 16 GB DDR5 4800 registered module produce under all-day load?

At the DDR5 standard 1.10 V the module draws minimal power and generates low heat; registered buffering adds negligible thermal load in a server chassis.
