Exact-fit server upgrade

This 384 GB kit contains six 64 GB DDR5 6400 RDIMMs built to the GIGABYTE MZ73-LM2 motherboard's memory-population rules. The modules are registered ECC with 2Rx4 organisation and 1.10 V operation so the platform recognises the full capacity at rated speed.

Registered ECC DDR5 limits

Registered buffering offloads the memory controller to allow full-slot population, while on-die ECC corrects single-bit errors before they reach the operating system. The 288-pin RDIMM form factor is mandatory for this board and will not work in UDIMM or SODIMM slots.

384 GB capacity headroom

Six ranks of 64 GB modules fill the supported DIMM count for maximum installed memory on this platform. Workloads that exceed 384 GB will require a motherboard or processor with higher per-slot and aggregate capacity limits.

Questions about this item

Should I buy the 384GB 6x64GB kit or a smaller capacity for my GIGABYTE MZ73-LM2?

The 384GB kit provides six 64GB DDR5-6400 RDIMMs that match the MZ73-LM2's population rules for full-capacity operation; choose a smaller kit only if your workload does not need the maximum supported memory.

Will the DDR5-6400 CL52 rating run at full speed once installed in the server?

Yes — the kit is spec-matched to the MZ73-LM2's memory controller, so the 6400 MT/s data rate and CL52 latency are recognised and sustained across all six slots when populated per the board's guidelines.

What does the 288-pin RDIMM interface limit in practice?

The 288-pin Registered DDR5 form factor only fits RDIMM slots on compatible server boards; it cannot be used in UDIMM or SODIMM sockets, and the registered buffer lets all six modules run at the rated 6400 MT/s without signal degradation.
