32GB DDR5-4800 ECC RDIMM Server Module

This 32GB DDR5-4800 ECC RDIMM is a registered server memory module built for enterprise workloads. It operates at 4800MHz with CAS latency 40 and runs at the standard 1.10V DDR5 voltage. The module uses a 1Rx4 rank configuration with major brand DRAM ICs and is a direct replacement for the Hynix HMCG84MEBQA174N part.

Suited for Servers Requiring Registered ECC DDR5

This module fits servers and workstations that require registered ECC DDR5 memory in a 288-pin DIMM form factor. It is not suitable for systems that only accept unbuffered UDIMMs, non-ECC memory, or a different DDR generation. Buyers needing a different capacity, rank layout, or voltage should verify their platform requirements before purchasing.

Registered ECC with 1Rx4 Rank Decides Compatibility

The registered ECC design combined with the 1Rx4 rank organisation determines whether this module will work in a given server. Systems that demand registered error-correcting memory and support this specific rank configuration can use it; those that require unbuffered or differently ranked modules cannot.

Questions about this item

Will the 1Rx4 ECC RDIMM need any firmware updates or component replacements over its service life?

The module uses major-brand DRAM ICs and is tested for dependable operation; no firmware updates or scheduled component replacements are required for the memory itself.

What is the first limit reached when the 32GB DDR5-4800 module runs at full load continuously?

The registered DDR5 design operates at the standard 1.10V and CL40 latency; sustained full-load operation stays within the JEDEC-defined voltage and timing envelope.

How much heat and power does the 288-pin RDIMM produce when the server runs all day?

At 1.10V the module draws only its rated DDR5 power budget, and with no heat spreader it relies on normal chassis airflow to stay within thermal limits.
