Exact-match 16GB DDR5-6400 RDIMM

This registered ECC module is built for the GIGABYTE MZ73-LM2 motherboard. It delivers 16 GB at 6400 MT/s with CL52 latency and 1.1 V operation. The 1Rx8 organization matches the board's memory-controller expectations so the full capacity is recognised at rated speed. Server administrators upgrading compatible systems receive a spec-matched part that maintains stability in multi-slot configurations.

288-pin keyed installation

The DIMM uses the standard 288-pin DDR5 RDIMM keying, so it seats in one orientation only and cannot be confused with UDIMM or SODIMM slots. Align the notch, press evenly until the retention clips click, and verify the module is fully seated before powering on. Common issues arise when population order in the manual is ignored or when a slot is left partially engaged, which prevents the system from posting at the rated frequency.

Sustained-load stability

Registered buffering reduces electrical load on the memory controller, allowing every populated slot to run continuously at 6400 MT/s without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during long compute or database workloads. The 1.1 V operating voltage keeps power draw consistent across extended duty cycles, supporting reliable uptime in production environments.

Questions about this item

How can I confirm the memory is running at 6400 MT/s and CL52 after installation?

Enter the system BIOS or UEFI and open the memory information screen; it should report DDR5-6400 with a CAS latency of 52. If the board shows a lower speed, enable the appropriate memory profile or manually set the frequency and timing to match the module's rated 6400 MT/s and CL52 values.

What comes in the package and do I need any extra parts for the GIGABYTE MZ73-LM2?

The box contains a single 16 GB 288-pin DDR5 RDIMM rated at 6400 MT/s, 1.1 V, CL52, 1Rx8, registered ECC. No additional components are required; the module plugs directly into the motherboard's DDR5 RDIMM slots.

Which version or capacity should I choose for the MZ73-LM2?

This listing provides the exact-match 16 GB DDR5-6400 registered ECC RDIMM (1Rx8, 1.1 V, CL52) validated for the GIGABYTE MZ73-LM2. Select this part when you need a single 16 GB module; add multiple units following the board's population rules for larger total capacities.
