Exact-match server upgrade

This 64 GB DDR5 RDIMM is built for the GIGABYTE MZ73-LM1 motherboard. Registered ECC architecture and a 2Rx4 layout let the board run every slot at the rated 6400 MT/s speed with CL52 latency at 1.1 V.

Registered ECC stability

The buffered design reduces electrical load on the memory controller, allowing full population without signal degradation. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption that could crash production workloads.

DDR5 population rules apply

Capacity per slot and total system memory depend on the motherboard's qualified-vendor list and BIOS revision. Installers must follow the manual's population order and maximum-density limits; exceeding them will prevent boot or force reduced speeds.

Questions about this item

Will the 2Rx4 rank layout on the GIGABYTE MZ73-LM1 require matched pairs when I expand memory later?

Each 64 GB module is a single 2Rx4 registered DIMM, so the board's population rules determine whether matching ranks are needed; consult the MZ73-LM1 manual for approved slot order before adding more.

At DDR5 6400 CL52, does the memory controller or the 1.10 V voltage limit sustained throughput first?

The DDR5 6400 data rate and CL52 latency set the timing ceiling, while the fixed 1.10 V supply defines the power envelope; whichever constraint the MZ73-LM1 memory controller hits first will throttle sustained bandwidth.

Without a heat spreader, how hot do these ECC RDIMMs get during all-day server workloads?

Bare DRAM on the 288-pin RDIMM relies on chassis airflow; registered buffering reduces electrical load per pin, but peak case temperature depends on your server's fan profile and DIMM spacing.
