Exact-Match Server Upgrade

This NEMIX RAM kit delivers 192 GB of DDR5 4800 memory in four 48 GB RDIMM modules. Each module operates at 1.10 V with CL40 latency and 2Rx8 registered ECC architecture. The kit is verified for the GIGABYTE MZ73-LM0 motherboard and uses major OEM Samsung, Micron or Hynix components.

Who It Suits And Who Should Look Elsewhere

This kit suits administrators upgrading a GIGABYTE MZ73-LM0 system that requires registered ECC DDR5 at 4800 MT/s. It is not for builds that accept only unbuffered UDIMM modules or that need speeds beyond 4800 MT/s. Buyers who want a different capacity, voltage or form factor should look at other kits.

Compatibility Checks Before Ordering

Confirm your motherboard manual supports 48 GB RDIMM modules and the exact population order for four DIMMs. Verify the BIOS version recognises 2Rx8 registered ECC at 1.10 V and CL40 timing. Ensure the system’s memory controller can address the full 192 GB capacity with this rank configuration.

Questions about this item

What motherboard is required for this 192GB 4x48GB DDR5 4800 CL40 ECC RDIMM kit to work?

This kit is verified compatible with the GIGABYTE MZ73-LM0 motherboard that supports DDR5 4800MHz PC5-38400. The board must accept 288-pin registered DIMMs with 2Rx8 organisation and 1.1V operation.

Can I mix these 2Rx8 registered ECC modules with existing UDIMMs in the same GIGABYTE MZ73-LM0 system?

No. Registered RDIMMs and unbuffered UDIMMs use different signalling and cannot be mixed on the same motherboard. The MZ73-LM0 requires registered modules in every populated slot.

How can I confirm the kit is running at its rated DDR5 4800 CL40 1.1V settings after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 4800MT/s, CAS latency reads CL40, voltage is 1.1V, and all four 48GB modules are detected for the full 192GB capacity.
