192GB DDR5-6400 ECC RDIMM kit for GIGABYTE MZ73-LM0

This 192GB kit contains twelve 16GB DDR5-6400 registered ECC modules built for the GIGABYTE MZ73-LM0 motherboard. Each stick runs at 1.1V with CL52 latency and a 1Rx8 organisation. The registered design lets every slot stay populated while the memory controller stays stable.

Registered ECC RDIMM form factor and 1Rx8 rank

The single specification that decides fitment is the 288-pin registered ECC RDIMM form factor combined with a 1Rx8 rank structure. The MZ73-LM0 memory controller expects exactly this registered buffer and rank layout; a UDIMM, SODIMM or different rank DIMM will not be recognised or will run at reduced capacity.

Pre-tested twelve-module kit

The bundle delivers twelve matched modules in one package so the board receives a complete, validated population set. No extra software or cables are included; the value is the factory-verified compatibility that lets the server boot at full 192GB capacity without manual tuning.

Questions about this item

Will the 6400 MT/s speed actually run at 6400 MT/s once installed in the Gigabyte MZ73-LM0?

The kit is spec-matched to the MZ73-LM0 memory controller, so all 12 modules initialise at DDR5-6400 with CL52 timings at 1.1 V without manual tuning.

What does the PC5-51200 rating cap in practice on this board?

PC5-51200 is the peak transfer rate for DDR5-6400; the registered RDIMM interface and the MZ73-LM0 memory controller both operate at that ceiling when all slots are populated.

Does the 288-pin RDIMM form factor fit the MZ73-LM0 DIMM slots without adapters?

Yes, the MZ73-LM0 requires 288-pin registered DIMMs, and this 12-module kit uses exactly that form factor for direct installation.
