  • DDR5-4800 speed with CL40 latency matches the motherboard's rated specification
  • Registered ECC design offloads the memory controller and corrects single-bit errors
  • 1 V operating voltage reduces power draw in fully populated configurations
  • 288-pin RDIMM form factor fits the GIGABYTE MZ73-LM1 motherboard exactly

384GB DDR5 4800 ECC RDIMM kit

This 384GB kit contains eight 48GB DDR5-4800 RDIMMs rated at CL40 and 1.10V. Registered ECC architecture and 2Rx8 organisation match the memory controller requirements of the GIGABYTE MZ73-LM1 motherboard for full-capacity operation.

Server builders needing registered ECC memory

Suited for administrators upgrading the GIGABYTE MZ73-LM1 to its maximum supported capacity with validated RDIMM modules. Not for desktop builders whose boards accept only unbuffered UDIMMs or SODIMMs, or for systems that cannot populate eight registered DIMM slots.

DDR5-4800 Registered ECC specification

The DDR5-4800 PC5-38400 registered ECC rating with 2Rx8 rank and 1.10V operation is the single specification that determines compatibility with the target motherboard. Only modules carrying this exact combination will be recognised at full speed and capacity.

Questions about this item

Does this 288-pin DDR5 RDIMM kit fit the GIGABYTE MZ73-LM1 motherboard without adapters?

Yes. The 384GB kit is spec-matched to the GIGABYTE MZ73-LM1 and uses the 288-pin RDIMM form factor that board requires.

What is the correct population order when installing all eight 48GB modules on the GIGABYTE MZ73-LM1?

Follow the motherboard manual for the approved DIMM population sequence; the server's memory controller expects the 2Rx8 rank layout and 1.1V operation for full 384GB recognition.

Do these registered ECC modules need active cooling or periodic replacement under normal server loads?

No heat spreader is included; rely on chassis airflow. Registered ECC RDIMMs have no scheduled replacement interval and are covered by a lifetime warranty.
