  • 768 GB total capacity from six 128 GB modules for dense server workloads
  • DDR5 5600 speed with CL46 latency delivers rated bandwidth without downclocking
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the motherboard's memory controller specification exactly
  • 288-pin RDIMM form factor fits the GIGABYTE MZ73-LM2 motherboard as intended

Exact-match server upgrade

This 768 GB kit delivers six 128 GB DDR5 ECC registered DIMMs rated at 5600 MT/s and CL46. It is built for administrators who need the precise rank, voltage and timing the GIGABYTE MZ73-LM2 memory controller expects for full-capacity operation.

2Rx4 registered ECC at 1.1 V

The modules use a dual-rank x4 organisation with on-die ECC and a registered buffer that offloads the controller when every slot is populated. This combination stops silent data corruption and keeps the system stable under sustained enterprise workloads.

288-pin RDIMM form factor for the MZ73-LM2

The kit fits only boards that accept 288-pin DDR5 RDIMMs and follow the MZ73-LM2 population rules. It frees you from mixing capacities or ranks, but it will not work in platforms that require unbuffered UDIMMs or SODIMM modules.

Questions about this item

Does the 768 GB capacity show up and run at 5600 MT/s on a GIGABYTE MZ73-LM2?

Yes, the kit is verified for that motherboard and its memory controller recognises all six 128 GB modules at the rated DDR5-5600 speed.

What does the PC5-44800 label limit in real use?

It caps the peak transfer rate at 44 800 MB/s, so sustained throughput cannot exceed that bandwidth ceiling.

Will the 288-pin RDIMMs fit the board's DIMM slots without a heat spreader?

Yes, the modules use the standard 288-pin registered form factor required by the MZ73-LM2 and have no spreader to interfere with slot latches.
