Server memory upgrade for Hynix replacements

This 32 GB DDR4 module operates at 2400 MHz with CL17 latency and 1.2 V. It is a registered ECC DIMM built with 2Rx4 organisation on a 288-pin form factor. The part is designed for server and workstation platforms that require error-correcting registered memory.

Direct replacement for five Hynix part numbers

The module matches HMA84GR7AFR4N-UH, HMA84GR7CJR4N-UH, HMA84GR7DJR4N-UH, HMA84GR7MFR4N-UH and HMAA4GR8AMR4N-UH. Using this single equivalent simplifies sourcing when the original Hynix SKUs are unavailable or discontinued.

Registered ECC with 2Rx4 ranking

The 2Rx4 registered ECC configuration is the specification that determines motherboard and chipset compatibility. Systems that require unbuffered non-ECC memory or a different rank structure cannot use this module.

Questions about this item

Will the 2Rx4 ECC RDIMM modules need any firmware updates or periodic replacement over their lifespan?

No firmware updates are required for these 2Rx4 ECC RDIMM modules. They are validated DDR4 2400 components designed to run for the system's lifetime without scheduled replacement.

What thermal or power ceiling appears first when this 1.2V DDR4 2400 kit runs continuously at full load?

The 1.20 V standard voltage and CL17 timing define the power envelope; sustained full-load operation stays within the DDR4 2400 specification without hitting a lower thermal limit first.

How much audible noise or extra heat does the registered 288-pin DIMM add when the server runs all day?

The registered 288-pin DIMM has no moving parts, so it produces no audible noise; its 1.2 V operation adds only nominal heat handled by normal server airflow.
