16GB DDR4 ECC RDIMM for Servers

This 16GB DDR4 2400MHz module is built for server and workstation systems that require error-correcting registered memory. It operates at the standard 1.2V voltage with a CL17 latency and a 2Rx4 rank configuration. The 288-pin DIMM form factor fits compatible DDR4 registered slots.

Direct Replacement for Hynix Part Numbers

The module serves as a compatible equivalent for Hynix HMA42GR7AFR4N-UH, HMA42GR7BJR4N-UH, and HMA42GR7MFR4N-UH part numbers. Using major brand chips, it allows administrators to replace or expand memory in qualified systems without changing existing specifications. Verification of the system's supported memory specifications remains essential before installation.

DDR4 2400 Registered DIMM Constraints

This memory runs at the DDR4 2400 PC4-19200 speed grade and requires a platform that supports registered ECC DIMMs. It will not function in consumer desktop boards that accept only unbuffered non-ECC modules. Mixing with different speeds, ranks, or voltage levels can prevent the system from booting or force all channels to the lowest common denominator.

Questions about this item

Will the 2Rx4 ECC RDIMM need any firmware updates or chip replacements over its lifetime?

No firmware or chip replacements are required; the module uses major-brand DRAM chips tested to A-Tech quality standards and is backed by a lifetime warranty.

What limits sustained throughput on this DDR4 2400 CL17 1.20V module?

The CL17 latency at 2400 MT/s and the registered buffer set the practical bandwidth ceiling during continuous workloads.

How much heat and power does a 16 GB DDR4 2400 1.2V RDIMM produce running 24/7 in a server?

At the standard 1.2 V DDR4 voltage the module draws minimal power and runs cool enough for dense server chassis without extra cooling.
