  • 768 GB total capacity from six 128 GB modules for maximum server density
  • DDR5 5600 speed with CL46 latency matches the board's rated timing for full-speed operation
  • Registered ECC design corrects single-bit errors and buffers signals for stable full-population loads
  • 1 V operating voltage aligns with DDR5 standard for efficient power draw
  • 288-pin RDIMM form factor fits the GIGABYTE MZ73-LM1 motherboard's memory slots exactly

768GB DDR5 5600 ECC RDIMM Kit

This NEMIX RAM kit delivers 768GB of DDR5 5600 memory across six 128GB Registered ECC RDIMM modules. It is built for servers and workstations that require high-capacity, error-correcting memory with registered buffering for full-slot stability. The modules operate at 1.1V with a CAS latency of CL46 and use a 288-pin form factor.

Suited for GIGABYTE MZ73-LM1 motherboards

This kit is verified for the GIGABYTE MZ73-LM1 motherboard running DDR5 5600. It suits administrators upgrading that specific platform to its maximum supported capacity with matched modules. Builders using consumer boards, laptops, or systems requiring unbuffered UDIMM or SODIMM memory should look elsewhere, as the registered RDIMM form factor and ECC function will not be compatible.

Registered ECC with 2Rx4 organization

The defining specification is the 2Rx4 Registered ECC architecture on DDR5 5600. This combination allows the memory controller to address all six slots at full 128GB density per module while correcting single-bit errors. If your system requires unbuffered memory, non-ECC operation, or a different rank structure, this kit will not function correctly.

Questions about this item

Will the 2Rx4 registered ECC modules need any firmware updates or reconfiguration if I add more memory later?

The kit is an exact-match upgrade for the GIGABYTE MZ73-LM1; follow the motherboard manual for approved population order and capacity limits when expanding.

What limits sustained throughput first — the CL46 latency or the DDR5 5600 bus?

The DDR5 5600 (PC5-44800) data rate sets the peak bandwidth ceiling; CL46 is the timing at that speed.

How much heat and power does the 768 GB kit produce when the server runs all day at 1.1 V?

Each 128 GB RDIMM operates at 1.10 V without a heat spreader; registered buffering reduces electrical load on the memory controller during continuous operation.
