Server-grade DDR5 RDIMM kit

This 512GB kit contains eight 64GB DDR5 6400 registered ECC modules built for the GIGABYTE MZ73-LM1 motherboard. Each stick uses a 2Rx4 organisation at 1.1V with CL52 timing so the memory controller recognises the full capacity at rated speed. It targets administrators who need maximum supported density in a single validated package.

Registered ECC with 2Rx4 layout

The registered buffer offloads the memory controller when all eight slots are populated while ECC corrects single-bit errors on the fly to prevent silent data corruption. The 2Rx4 rank structure and 1.1V operating point match the board's population rules exactly so the system boots at DDR5 6400 without manual tuning.

Eight-module kit only

The package supplies eight 288-pin RDIMMs and nothing else; no heat spreaders, no software utilities and no alternative form factors are included. Builders who need fewer modules or a different rank configuration must source a separate kit because this SKU is fixed at eight pieces.

Questions about this item

What does the 6400 MT/s rating deliver once the kit is installed in a GIGABYTE MZ73-LM1?

The modules run at the board's DDR5 6400 speed with CL52 latency, giving the rated 51200 MB/s bandwidth across all eight slots when populated per the motherboard's population rules.

How does the 288-pin RDIMM interface and registered design affect what the memory controller can handle?

The registered buffer reduces electrical load on the controller, allowing all eight 64 GB DIMMs to operate at the full 6400 MT/s without signal degradation, while ECC corrects single-bit errors in flight.

What physical clearance and slot layout does the 8 x 64 GB kit need on the MZ73-LM1?

Each DIMM is a standard-height 288-pin RDIMM without a heat spreader, so they fit the server's DIMM slots side-by-side; follow the manual's population sequence for the 8-module configuration.
