128GB DDR5 RDIMM kit for GIGABYTE MZ73-LM1

This NEMIX RAM kit delivers 128GB across two 64GB DDR5-6400 Registered ECC modules. It matches the exact rank, voltage and timing the GIGABYTE MZ73-LM1 memory controller expects for full-capacity recognition at rated speed. The 288-pin RDIMM form factor is the only type this board accepts.

Upgrade from lower-capacity or unbuffered DDR5

Replacing smaller RDIMMs or non-ECC UDIMMs with this 2Rx4 Registered kit enables the board to run every slot fully populated at 6400MT/s while adding on-the-fly single-bit error correction. The jump is worth it when workloads demand maximum registered capacity and data integrity without unplanned reboots.

DDR5 RDIMM platform limits

Registered DDR5 architecture offloads the memory controller so all slots operate at full capacity, but the motherboard manual still governs supported populations and installation order. Buyers who need more storage than 128GB or who require UDIMM or SODIMM form factors cannot use this kit.

Questions about this item

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

Yes, the kit uses the 288-pin DDR5 RDIMM form factor required by the GIGABYTE MZ73-LM1 motherboard. It is not a UDIMM or SODIMM, so it matches the board's physical slot specification exactly.

What is the correct installation order for the two 64GB modules on this board?

Install the modules in the DIMM slots specified by the GIGABYTE MZ73-LM1 manual for a two-DIMM population. The motherboard manual defines the approved population order; following it ensures the memory controller recognizes both 64GB modules at the rated DDR5 6400 speed.

When should the ECC RDIMM modules be replaced in a production server?

Replace modules if the system logs report uncorrectable ECC errors, repeated correctable error thresholds are exceeded, or the server fails memory diagnostics during POST. Registered ECC RDIMMs correct single-bit errors on the fly, but persistent faults indicate hardware degradation requiring replacement.
