48GB DDR5 ECC RDIMM for GIGABYTE MZ73-LM2

This 48GB DDR5 5600 CL46 registered ECC module is built for the GIGABYTE MZ73-LM2 motherboard. It delivers 1.1V operation and a 2Rx8 organization that matches the board's memory controller requirements. The registered design allows full-slot population without signal degradation. It targets server and workstation users who need verified compatibility and error correction.

Installation requires matching the motherboard

The 288-pin RDIMM form factor fits only registered DIMM slots; it will not work in UDIMM or SODIMM sockets. No heat spreader is included, so airflow across the modules must be adequate. Common issues arise when DIMMs are installed in the wrong slot order or when mixed with different ranks or voltages. Always follow the board manual's exact population sequence.

Check your system manual for supported capacity

Verify that the GIGABYTE MZ73-LM2 motherboard supports 48GB per DIMM and the total memory limit you intend to populate. Confirm the approved DIMM population order and any BIOS version requirements. Ensure the platform accepts registered ECC DDR5 at 5600 MT/s with CL46 timing. Do not assume compatibility with other boards or form factors.
