16GB DDR5 4800 ECC RDIMM

This 16GB DDR5 4800 ECC RDIMM module is built for server and workstation systems that require registered memory with error correction. It replaces specific Hynix part numbers including HMCA2GR8MJR8C-EB and the HMCG78MEBRA series. The module runs at 4800 MT/s with a CAS latency of 40 and operates at the standard 1.10 V.

Suited for registered DDR5 slots only

This module fits systems designed for 288-pin DDR5 RDIMMs with ECC support and a 1Rx8 rank structure. Builders using platforms that accept only unbuffered UDIMMs or that lack DDR5 registered memory support should look at other memory types. The single-rank x8 organisation suits configurations that populate multiple channels per controller.

Registered ECC with 1Rx8 organisation

The deciding specification is the combination of registered buffering, ECC capability and 1Rx8 rank layout on a 288-pin DDR5 form factor. Only motherboards and server boards qualified for DDR5 RDIMMs with this rank configuration will recognise and stabilise the module at 4800 MT/s.

Questions sur cet article

Should I choose the 16GB DDR5 4800 module or a different capacity for my server?

This listing provides a single 16GB DDR5-4800 ECC RDIMM. Select this module when your system requires a 1Rx8 registered DIMM at 1.1V to match the Hynix part numbers listed.

What does the 4800MHz speed rating deliver in an actual server workload?

The module runs at DDR5-4800 (PC5-38400) with CL40 latency, providing the rated bandwidth and error-correction for registered server platforms that support this speed grade.

How does the 288-pin RDIMM interface limit memory configuration in practice?

The 288-pin registered DIMM fits DDR5 RDIMM slots only; the 1Rx8 organisation and ECC function require a server or workstation chipset that supports registered memory.
