Exact-match DDR5-6400 ECC RDIMM

This 32 GB DDR5-6400 registered ECC module is built for the GIGABYTE MZ73-LM2 motherboard. It runs at CL52 with 1.1 V and a 2Rx8 organisation, delivering the precise rank, voltage and timing the server memory controller expects for full-capacity recognition at rated speed.

Pre-installation checklist

Verify that your MZ73-LM2 system manual lists DDR5-6400 RDIMM support, the approved DIMM population order and the maximum capacity per slot. The board requires 288-pin registered modules; UDIMM or SODIMM variants will not fit or function. Confirm the BIOS version supports the target capacity before ordering.

Build quality and daily use

Major OEM chips from Samsung Micron or Hynix underpin enterprise-grade stability. The registered architecture buffers each signal so every slot runs fully populated while on-die ECC corrects single-bit errors in flight. No heat spreader is fitted so ensure chassis airflow meets the vendor's thermal guidelines for dense memory configurations.
