16GB DDR5 5600 ECC RDIMM

This 16GB DDR5 5600 ECC RDIMM is a registered server memory module built for 288-pin DDR5 platforms. It runs at PC5-44800 with a CAS latency of 40 and operates at the standard 1.10V. The single-rank 1Rx8 design uses major-brand DRAM ICs and matches the Hynix HMCG78AGBRA series part numbers.

Suits registered DDR5 servers.

This module fits servers and workstations that require registered ECC DDR5 memory. It is not for systems that accept only unbuffered UDIMMs or that cannot support registered DIMMs. Buyers needing a heat spreader should look elsewhere because this module has none. It is also not for platforms limited to lower DDR5 speeds.

Registered ECC with 1Rx8 rank

The deciding specification is the registered ECC design with a single 1Rx8 rank at DDR5 5600. This combination determines whether the module will be accepted by the memory controller and whether it provides the error-correction and signal-integrity features required by the target server platform.
