Exact-match DDR5 upgrade

This 16 GB DDR5-4800 Registered ECC RDIMM is built for the GIGABYTE MZ73-LM1 motherboard. It runs at PC5-38400 with CL40 latency at 1.1 V, using a single-rank 1Rx8 layout. The module arrives new and ready for server deployment.

Registered architecture for full population

The 288-pin RDIMM form factor fits the board's registered memory slots, not UDIMM or SODIMM sockets. Registered buffering lets every supported slot run fully populated at rated speed, while on-die ECC corrects single-bit errors before they reach the OS. No heat spreader is included, so airflow must come from the chassis.

Suited for validated server builds

This kit suits administrators upgrading or repairing the specified GIGABYTE platform with a guaranteed part number match. It is not for desktop boards that require unbuffered memory, for laptops needing SODIMMs, or for systems that do not support registered ECC DDR5 at this speed and rank configuration.

Questions about this item

How much power does the 1.1 V DDR5 RDIMM draw under sustained load?

The module operates at 1.10 V; actual power draw depends on the server platform and workload.

How hot or loud does the 288-pin ECC RDIMM get when running continuously?

No heat spreader is fitted; temperature and airflow noise are determined by the server chassis and fan profile.

Which motherboard must I already own for this 1Rx8 CL40 kit to work?

It is validated for the GIGABYTE MZ73-LM1 motherboard; other boards may require different population rules.
