  • 1Rx8 rank organisation enables full 8-slot population on supported platforms

Exact-match DDR5 kit for GIGABYTE MZ73-LM2

This 128 GB kit contains eight 16 GB DDR5 RDIMMs built to the specifications the GIGABYTE MZ73-LM2 expects. Registered ECC architecture and 1.10 V operation match the board's memory controller requirements for full-capacity recognition.

Registered ECC RDIMM form factor decides fit

The modules are 288-pin DDR5 RDIMMs with a 1Rx8 organisation, not UDIMMs or SODIMMs. Registered buffering offloads the controller so every slot runs populated at the rated 6400 MT/s speed, while on-die ECC corrects single-bit errors before they reach production workloads.

128 GB headroom for dense virtualization

Eight populated slots deliver the maximum capacity this kit provides, handling large databases, container clusters and multi-tenant VMs. Workloads that exceed 128 GB or require higher frequencies than DDR5-6400 will need a different platform.

Questions about this item

What does the 6400 speed rating mean when the kit is installed in a GIGABYTE MZ73-LM2?

The modules run at DDR5 6400 with CL52 latency and 1.1V voltage, delivering the rated throughput the motherboard's memory controller expects when all eight slots are populated with 1Rx8 registered ECC RDIMMs.

How does the PC5-51200 designation relate to the DDR5 6400 specification?

PC5-51200 is the module bandwidth designation that corresponds to DDR5 6400, confirming the kit matches the motherboard's supported memory standard.

What physical requirements must the motherboard meet to accept this 8-module kit?

The board needs eight 288-pin DDR5 RDIMM slots and must support 1Rx8 registered ECC modules at 1.1V to recognise the full 128GB capacity.
