Server-grade DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 256 GB of DDR5 memory across four 64 GB Registered ECC RDIMMs. It is built for servers and workstations that require error correction and registered buffering for stable operation under continuous load. The modules run at 6400 MT/s with CL52 latency at 1.1 V.

Straightforward DIMM installation

The 288-pin RDIMMs seat in standard DDR5 RDIMM slots on the GIGABYTE MZ73-LM0 motherboard. No heat spreaders are fitted, so clearance is minimal. Common issues include mixing registered and unbuffered DIMMs, populating slots in the wrong order, or skipping the BIOS update that enables full-speed operation.

Verify motherboard population rules

Check the MZ73-LM0 manual for the exact DIMM population sequence, maximum supported capacity per slot, and any BIOS version requirements before ordering. Ensure your system supports 2Rx4 Registered ECC modules at 1.1 V. This kit is not for boards that only accept UDIMMs or SODIMMs.
