Exact-fit DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 64 GB as two 32 GB DDR5-4800 Registered ECC RDIMMs built to the precise 2Rx8, 1.1 V, CL40 specification the GIGABYTE MZ23-SU0 motherboard expects. The modules are validated for full-capacity recognition and rated-speed operation in that platform.

Verified compatibility and registered architecture

Supplier verification confirms the 288-pin RDIMM form factor matches the board's memory-population rules, eliminating the risk of mismatched UDIMM or SODIMM modules. Registered buffering offloads the memory controller so every slot runs fully populated, while on-die ECC corrects single-bit errors before they cause silent data corruption or unplanned reboots.

Suited for MZ23-SU0 upgrades only

This kit serves administrators upgrading a GIGABYTE MZ23-SU0 system that requires DDR5-4800 Registered ECC memory in a 2Rx8 configuration. Builders needing unbuffered UDIMMs, different capacities, speeds, voltages, or form factors should look at other memory types.
