  • 192GB kit fills every slot at full rated speed
  • Registered ECC architecture prevents silent data corruption under load
  • CL52 latency and 1.1V voltage match board spec exactly
  • 2Rx4 dual-rank Samsung Micron Hynix chips ensure stable population
  • 288-pin RDIMM form factor fits GIGABYTE MZ73-LM0 motherboard

Exact-match server kit

This 192 GB kit contains two 96 GB DDR5-6400 RDIMMs built to the GIGABYTE MZ73-LM0 motherboard's specifications. Registered ECC circuitry and a CL52 latency at 1.10 V let every slot run fully populated at the rated PC5-51200 speed.

For registered-ECC platforms only

The modules suit servers and workstations that require 288-pin registered DDR5 with 2Rx4 organisation. Systems needing unbuffered UDIMMs, SODIMMs, non-ECC memory or a different voltage will not accept this kit.

Ready-to-install pair

The matched pair eliminates population-order guesswork and ensures the memory controller sees the correct rank and timing profile immediately. No extra cables, software or heat spreaders are included.

Questions about this item

What motherboard must I already have for this 192GB DDR5-6400 kit to be recognised at full capacity?

The kit is validated for the GIGABYTE MZ73-LM0 motherboard; its 288-pin RDIMM form factor and 1.10V operation match that board's memory controller requirements exactly.

Will these 2Rx4 registered ECC modules work alongside any existing DDR5 RDIMMs I keep in the same server?

Mixing ranks or capacities can prevent full-speed operation; the board's population rules should be followed and all slots ideally filled with identical 96GB 2Rx4 modules for stable 6400MT/s performance.

How do I confirm the system is running the memory at the rated 6400MT/s with ECC active?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report DDR5-6400, CL52, 1.10V, registered ECC and show the full 192GB capacity.
