Server-ready DDR5 ECC RDIMM kit

This 288GB kit contains six 48GB DDR5 5600 registered ECC modules built for the GIGABYTE MZ73-LM1 motherboard. Each stick runs at 1.1V with CL46 latency and a 2Rx8 organisation. The registered design lets every slot stay populated at full capacity without overloading the memory controller.

Thermals noise and power draw

Operating at 1.1V keeps power draw low for a fully loaded six-channel configuration. No heat spreaders are fitted so airflow across the bare PCBs handles cooling in a chassis with directed server airflow. Registered buffering reduces electrical load on the controller which also limits heat at the socket.

Build quality and daily implications

Modules use major OEM Samsung Micron or Hynix chips and ship as a matched six-piece kit for consistent timing across all channels. The 288-pin RDIMM form factor fits only registered DIMM slots not UDIMM or SODIMM sockets. Buyers needing non-ECC unbuffered memory or a different capacity per module should look elsewhere.

Questions about this item

How do I install the six 48 GB DDR5 RDIMM modules in the GIGABYTE MZ73-LM1, and which slot order do people often get wrong?

Populate the DIMM slots in the exact sequence shown in the MZ73-LM1 manual for a six-module configuration; the board requires registered ECC RDIMMs in a specific channel order to recognize all 288 GB at DDR5-5600.

What maintenance or replacement will this 288 GB DDR5 ECC RDIMM kit need over its service life?

No periodic maintenance is required; if a module fails, the lifetime replacement warranty covers a direct swap of the defective 48 GB RDIMM.

What limit appears first when the kit runs sustained workloads at DDR5-5600 CL46?

The registered ECC architecture keeps every slot stable at full 1.10 V, so the first boundary is the motherboard's maximum supported capacity rather than a thermal or voltage ceiling.
