  • 288-pin RDIMM form factor fits the GIGABYTE MZ73-LM0 memory slots precisely

Exact-match 768 GB DDR5 kit

This 768 GB kit contains eight 96 GB DDR5-4800 RDIMMs built to the exact rank, voltage and timing the GIGABYTE MZ73-LM0 memory controller expects. Registered ECC architecture with CL40 latency at 1.1 V lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. The modules use major OEM Samsung, Micron or Hynix chips and carry the NEMIX RAM Original Series label.

288-pin RDIMM form factor and registered design

Each module fits the 288-pin DDR5 RDIMM sockets required by the MZ73-LM0; UDIMM or SODIMM variants will not seat. The registered buffer offloads the memory controller so all eight slots operate at full capacity without signal degradation. No heat spreaders are fitted, so airflow across the bare PCB is the only cooling path — plan chassis ventilation accordingly.

Check manual for population rules

Server memory support varies by model and BIOS revision; consult the GIGABYTE MZ73-LM0 manual for approved DIMM population order, maximum supported capacity per slot and any required firmware updates before ordering. This kit is not suitable for systems that require UDIMM, SODIMM or non-ECC memory, or for boards limited to lower densities or different voltages.

Questions about this item

What speed does the DDR5-4800 PC5-38400 interface deliver on the GIGABYTE MZ73-LM0?

The kit runs at 4800 MT/s (PC5-38400) with CL40 latency at 1.1 V, matching the motherboard's rated DDR5 speed for full-capacity operation.

Does the 288-pin RDIMM form factor fit the GIGABYTE MZ73-LM0 slots?

Yes, each 96 GB module is a 288-pin registered DIMM, the exact form factor the MZ73-LM0 requires; UDIMM or SODIMM modules will not seat.

What population order should I follow when installing all eight 2Rx4 modules?

Consult the MZ73-LM0 manual for the approved DIMM sequence; the board's population rules determine which slots take the 2Rx4 RDIMMs first for stable 768 GB operation.
