Exact-match server upgrade

This 48 GB DDR5-4800 RDIMM delivers the exact rank, voltage and timing the GIGABYTE MZ73-LM1 memory controller expects. Registered ECC architecture with CL40 latency and 1.1 V operation lets every slot run fully populated at rated speed. The 288-pin form factor matches the board's physical and electrical requirements without adaptation.

Verified fitment for one platform

The module is tested specifically for the MZ73-LM1 motherboard, removing guesswork from population order and capacity limits. No extra software, heat spreaders or cables are bundled; the package contains only the single 48 GB DIMM. Compatibility is limited to systems that accept 2Rx8 registered DDR5 at 4800 MT/s.

Suited for single-board capacity increases

Ideal for administrators expanding memory on a validated GIGABYTE MZ73-LM1 platform where registered ECC is required. Not suitable for desktop boards that need unbuffered UDIMMs, for laptops requiring SODIMMs, or for servers that demand a different rank configuration or voltage. Buyers needing multi-DIMM kits or higher densities should verify their manual first.

Questions about this item

Will the 288-pin RDIMM require any firmware updates or component swaps to stay reliable in a GIGABYTE MZ73-LM1 system?

No firmware updates or component swaps are required; the module is an exact-match DDR5-4800 2Rx8 registered ECC part that the memory controller recognises at full capacity and rated speed.

What limit appears first when the 48 GB DDR5-4800 CL40 1.1 V registered ECC kit runs sustained workloads on the MZ73-LM1?

The memory controller’s maximum supported frequency of 4800 MT/s is the first ceiling; the module already operates at that spec, so no higher data rate is possible.

How much heat and power does a 48 GB DDR5-4800 2Rx8 CL40 1.10 V registered ECC RDIMM generate during continuous all-day operation?

At the rated 1.10 V the module draws only the power needed for 4800 MT/s CL40 operation, and with no heat spreader it relies on normal chassis airflow to stay within thermal limits.
