48 GB DDR5 RDIMM for GIGABYTE MZ73-LM1

This 48 GB DDR5-6400 registered ECC module is built to the exact rank, voltage and timing the GIGABYTE MZ73-LM1 memory controller expects. The 2Rx8 organisation and 1.1 V operation let the board recognise the full capacity and run at the rated PC5-51200 speed without manual tuning.

Suited for servers that require registered ECC

This module fits workloads that need error correction and registered buffering for full-slot population stability. It is not for systems that accept only unbuffered UDIMMs, for builds that need a lower CL timing than CL52, or for any platform that does not support DDR5 288-pin RDIMMs.

Single-module kit with lifetime support

The package contains one 48 GB RDIMM using major OEM DRAM chips and no heat spreader. A lifetime replacement warranty and free US-based technical support cover the module, while the spec-matched design eliminates trial-and-error population issues.

Questions about this item

What motherboard slot does the 288-pin RDIMM require to install?

It fits a DDR5 RDIMM slot on the GIGABYTE MZ73-LM1 motherboard; the board must support registered ECC modules at 1.1 V.

Will this 2Rx8 registered ECC kit run with existing UDIMM or non-ECC modules already in the server?

No, registered ECC RDIMMs cannot be mixed with unbuffered or non-ECC memory; the MZ73-LM1 requires a uniform RDIMM population.

How do I confirm the kit is operating at DDR5 6400 CL52 after installation?

Check the BIOS memory information screen or a tool such as dmidecode; it should report 6400 MT/s, CL52, 1.1 V and 48 GB per module.
