  • 1 V operation at 288-pin RDIMM form factor fits the server's DIMM slots

Exact-match DDR5-4800 RDIMM for GIGABYTE MZ73-LM0

This 48GB registered ECC module runs at DDR5-4800 (PC5-38400) with CL40 latency at 1.1V. The 2Rx8 organisation and 288-pin RDIMM form factor match the motherboard's memory-controller requirements so the system recognises the full capacity at rated speed. It is built for servers and workstations that need registered DIMMs with error-correcting code.

Replaces unbuffered or slower DDR5 modules

A UDIMM or lower-speed DDR5 DIMM will not register correctly on this board and can limit population to fewer slots. The jump is worth it when you need every slot populated at 48GB with registered buffering and ECC to prevent silent data corruption under sustained load.

Verify manual for population rules

Confirm the motherboard manual for approved DIMM population order, maximum supported capacity per slot, and any BIOS version requirements before ordering. Registered ECC RDIMMs must be installed in the sequence the vendor specifies or the system may not POST.

Questions about this item

Does this 288-pin DDR5 RDIMM fit the GIGABYTE MZ73-LM0 motherboard slots?

Yes — it is a 288-pin Registered DDR5 DIMM built to the exact form factor the MZ73-LM0 requires, not a UDIMM or SODIMM.

What installation step is most often missed when adding this 2Rx8 ECC module?

Follow the motherboard manual's DIMM population order; the board must be powered off and the module seated until both retention clips click.

When will the 48GB DDR5 4800 CL40 kit need replacement?

DDR5 RDIMMs have no moving parts; they run at 1.1 V and only need replacement if a hardware fault appears or capacity requirements grow.
