Server-specific DDR5-4800 RDIMM kit

This NEMIX RAM kit delivers 256 GB across four 64 GB DDR5 Registered DIMMs rated at 4800 MT/s with CL40 latency and 1.1 V operation. The modules use 2Rx4 organisation and on-die ECC to meet enterprise memory-controller requirements.

Verified for GIGABYTE MZ73-LM1 boards

The 288-pin Registered form factor matches the motherboard's slot specification and population rules, so every slot can be filled without signal-integrity loss. Builders needing unbuffered UDIMMs, lower capacities, or non-ECC memory must choose a different product.

Registered ECC with 2Rx4 rank structure

Registered buffering offloads the memory controller while ECC corrects single-bit errors in flight, enabling full-capacity operation across all four slots on the GIGABYTE MZ73-LM1 platform.

Questions about this item

Will the 288-pin RDIMM modules fit the GIGABYTE MZ73-LM1 motherboard slots?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor that the MZ73-LM1 requires; it is not a UDIMM or SODIMM so it matches the board's physical slot keying exactly.

What is the correct population order when installing all four 64 GB sticks?

Consult the MZ73-LM1 manual for the approved DIMM sequence; the board's memory-population rules dictate which slots must be filled first for full 256 GB recognition.

Does the registered ECC design reduce long-term maintenance compared with unbuffered memory?

Registered buffering offloads the memory controller and ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots that would otherwise require troubleshooting or module replacement.
