16GB DDR4 3200 ECC RDIMM

This 16GB DDR4 3200 ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It replaces Hynix HMA82GR7CJR8N-XN and HMA82GR7DJR8N-XN parts in compatible systems. The module uses Major Brand chips and runs at the standard 1.20V voltage.

Installation and common issues

Installation follows the standard 288-pin DIMM procedure: align the notch, press firmly until the retention clips lock, and confirm the module is seated evenly. The most frequent issue is purchasing registered ECC memory for a platform that only accepts unbuffered non-ECC DIMMs, which prevents the system from posting.

Registered ECC with 2Rx8 organisation

The single specification that determines fit is the registered ECC design with 2Rx8 organisation running at CL22 latency. Only systems that explicitly support DDR4 RDIMM modules with this rank configuration will recognise and operate the memory correctly.

Questions about this item

How can I confirm the 16GB DDR4 3200 ECC RDIMM is running at CL22 1.20V after installation?

Enter the server BIOS or use a tool like CPU-Z to verify the memory reports 3200 MT/s, CL22 timings, 1.20 V, registered ECC, and 2Rx8 organisation.

What comes in the box and what must I source separately?

The package contains one 288-pin 16 GB DDR4 3200 ECC RDIMM module; no brackets, cables, or additional DIMMs are included.

When should I choose this 16GB 2Rx8 CL22 module over a different capacity or rank?

Select this module when your server requires a single 16 GB registered ECC DIMM at 3200 MT/s with 2Rx8 density and CL22 latency.
