Exact-fit 512GB DDR5 kit for GIGABYTE MZ73-LM2

This 512GB kit delivers eight 64GB DDR5-6400 RDIMMs tuned to CL52 at 1.1V. The 2Rx4 registered ECC design matches the GIGABYTE MZ73-LM2 motherboard's required pin-out, rank structure and voltage so the system recognises full capacity at rated speed without manual tuning.

Sustained enterprise stability under full population

Registered buffering offloads the memory controller, allowing all eight slots to run continuously at 6400 MT/s without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during prolonged, memory-intensive workloads.

Bare-module build for dense server chassis

Modules ship without heat spreaders, reducing height for tight 1U or blade layouts where airflow is managed by the chassis. The 288-pin RDIMM keying prevents accidental insertion into UDIMM or SODIMM slots, and the kit's exact part-number match simplifies compliance with the board's population rules.

Questions about this item

How much power does the 1.10 V DDR5 6400 kit draw when all eight modules run continuously?

Each module operates at 1.10 V; total power depends on your server's memory controller and workload, so consult the platform's specifications for full-system figures.

What motherboard slot and population rules are required for this 288-pin RDIMM kit to function?

The kit requires a motherboard with eight DDR5 RDIMM slots — such as the GIGABYTE MZ73-LM2 — populated according to that board's approved DIMM order.

Will the registered ECC design work alongside older DDR5 RDIMMs already installed in my server?

Mixing ranks, speeds or vendors is not recommended; the board's memory controller expects identical 2Rx4 CL52 modules in every populated slot for stable operation.
