Server DDR5 ECC RDIMM 16GB

This A-Tech 16GB DDR5 5600 ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It uses Samsung DRAM chips and operates at the standard 1.10V DDR5 voltage. The single-rank 1Rx8 organisation suits platforms that populate multiple channels per processor.

Registered ECC with 1Rx8 rank

The decisive specification is the registered ECC RDIMM format combined with a 1Rx8 rank structure. This module runs at DDR5 5600 speed with a CAS latency of 40 and fits 288-pin DIMM slots. Systems must support registered ECC DDR5 memory; unbuffered or non-ECC platforms cannot use this part.

Suits DDR5 servers needing registered ECC

IT teams upgrading compatible Samsung M321R2GA3EB0-CWM configurations or expanding DDR5 server capacity will find this module a direct match. Buyers whose motherboards accept only unbuffered UDIMM memory or require a different rank configuration should look at other memory types.

Questions about this item

What does the 5600 MHz DDR5 speed mean for actual server performance?

The module runs at DDR5-5600 (PC5-44800) with CL40 latency, delivering the rated bandwidth when the platform memory controller is configured for that speed.

How does the ECC RDIMM interface affect usable capacity and speed?

Registered ECC adds a buffer chip that stabilises heavy loads; the 1Rx8 organisation presents a single rank per channel, so the full 16 GB is usable at the rated 5600 MT/s.

Will the 288-pin DDR5 DIMM fit my server board without extra hardware?

Yes — it is a standard 288-pin DDR5 RDIMM that installs directly into any DDR5 RDIMM slot; no heat spreader means low-profile clearance is not an issue.
