Exact-match DDR5 ECC RDIMM kit

This 384GB kit contains twelve 32GB DDR5 4800 RDIMMs built to the GIGABYTE MZ73-LM1 motherboard's exact specifications. Each module is a 2Rx8 registered ECC DIMM running at 1.1V with CL40 latency. The registered design and ECC function are required for this server platform to operate at full capacity.

DDR5-4800 registered memory limits

DDR5-4800 (PC5-38400) sets the maximum data rate this motherboard can achieve with these modules; the board will not run them faster. Registered architecture is mandatory for full-slot population, and the 288-pin RDIMM form factor is the only type the memory slots accept. ECC correction operates automatically at this speed.

Upgrade from smaller or unregistered kits

This kit replaces partial populations or UDIMM sets that cannot fill every slot or lack error correction. The jump is worth it when the workload needs the full 384GB capacity and the stability of registered ECC across all channels. Builders who need a different form factor or non-ECC memory cannot use this product.

Questions about this item

Should I buy this 12-module 384 GB kit or look for a different capacity?

This kit provides exactly 384 GB across 12 matched 32 GB modules, the full population the GIGABYTE MZ73-LM1 supports at DDR5 4800 speed.

What does the DDR5 4800 rating actually deliver once installed?

The modules run at 4800 MT/s with CL40 latency and 1.10 V, giving the rated PC5-38400 throughput when the board trains them at that speed.

How does the 288-pin RDIMM interface limit performance on this motherboard?

The registered 288-pin DDR5 RDIMM form factor is what the MZ73-LM1 requires; it enables full 12-slot population at 4800 MT/s with ECC active.
