  • ECC corrects single-bit errors on the fly to prevent silent data corruption
  • Validated for the Gigabyte MZ73-LM2 motherboard's 288-pin RDIMM slots

Exact-match 96GB DDR5-6400 kit

This 96GB kit contains two 48GB DDR5 RDIMMs rated at 6400 MT/s (PC5-51200) with CL52 latency and 1.10V operation. It is built specifically for the GIGABYTE MZ73-LM2 motherboard, using the 288-pin Registered ECC form factor that board requires. The 2Rx8 organisation matches the platform's memory controller expectations for full-capacity recognition.

Sustained-load behaviour

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed without signal degradation. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 2Rx8 density keeps all ranks active under continuous throughput workloads typical of server deployments.

Thermals and power

Modules operate at the standard DDR5 1.10V with no heat spreader, relying on chassis airflow for cooling. Power draw scales with the 96GB capacity and 6400 MT/s data rate under normal server utilisation. Acoustic profile is dictated by system fans rather than the memory itself, which has no moving parts.

Questions about this item

How much power does the 1.1V DDR5 6400 RDIMM kit draw when the server runs continuously?

Each module operates at 1.1V, the standard voltage for DDR5 6400 RDIMMs. Actual power draw depends on the CPU memory controller and the number of populated slots on the GIGABYTE MZ73-LM2 board.

Does the GIGABYTE MZ73-LM2 motherboard need a specific BIOS version or CPU to recognise the 2Rx8 48GB density?

The kit is built to the exact 2Rx8 48GB specification the MZ73-LM2 memory controller expects. Consult the motherboard manual for supported capacities, approved DIMM population order, and any required BIOS updates before installation.

Can I mix these 48GB 2Rx8 ECC RDIMMs with smaller RDIMMs already installed in the MZ73-LM2?

Mixing different capacities or ranks is possible only if the MZ73-LM2 manual explicitly allows it. Registered ECC modules must follow the board's population rules; mismatched ranks can prevent the system from booting or running at the rated 6400 speed.
