Exact-match server kit

This NEMIX RAM kit delivers 256 GB as two 128 GB DDR5 RDIMMs rated at 5600 MT/s with CL46 latency. Registered ECC architecture and 1.1 V operation meet the precise electrical and timing requirements of the GIGABYTE MZ73-LM2 motherboard for full-capacity recognition at rated speed.

DDR5 RDIMM platform limits

DDR5 registered DIMMs use a 288-pin interface that is physically and electrically incompatible with UDIMM or SODIMM slots. The registered buffer reduces electrical load on the memory controller, enabling stable operation when all supported slots are populated, while ECC corrects single-bit errors to prevent silent data corruption.

Pre-installation checklist

Verify the MZ73-LM2 manual for maximum supported capacity per slot, approved population order, and any BIOS version requirements before ordering. Confirm the system accepts 2Rx4 registered modules at 1.1 V and that the chassis provides clearance for standard-height RDIMMs. This kit is not suited for workstations or desktops that require unbuffered non-ECC memory.

Questions about this item

Should I choose the 256 GB kit or a smaller capacity for my GIGABYTE MZ73-LM2?

The 256 GB kit uses two 128 GB RDIMMs, matching the board's DDR5 5600 registered ECC requirements; select it when you need maximum capacity and have two free slots.

What does the DDR5 5600 speed mean for real-world server performance?

DDR5 5600 delivers 44800 MT/s data rate with CL46 latency at 1.1 V, giving high bandwidth for virtualisation and database workloads while registered buffering keeps all slots stable at full load.

How does the 288-pin RDIMM interface limit what I can install?

The 288-pin registered ECC form factor is required by the MZ73-LM2; UDIMM or SODIMM modules will not fit or function, so only DDR5 RDIMMs with matching rank and voltage are compatible.
