Exact-match upgrade for GIGABYTE MZ73-LM2

This 384GB kit delivers four 96GB DDR5-4800 Registered ECC RDIMMs built to the board's precise rank, voltage and timing requirements. The modules run at 1.1V with CL40 latency so the memory controller recognises the full capacity at rated speed. It is intended for administrators who need maximum supported memory on this specific server platform. Buyers who need unbuffered UDIMMs or SODIMM form factors cannot use this kit.

Registered DDR5-4800 interface constraints

The PC5-38400 standard sets the electrical and timing envelope these modules occupy; population rules on the MZ73-LM2 then dictate which slots must be filled first and whether mixed ranks are permitted. Exceeding the board's qualified capacity per channel or ignoring the approved population order will prevent the system from posting. The 2Rx4 organisation helps density but the memory controller still enforces its own slot limits.

Straightforward RDIMM installation

Align the 288-pin modules with the keyed slots and press until the retention clips latch; no heat spreader means clearance is rarely an issue. The frequent error is populating slots in the wrong sequence or leaving a required slot empty, which causes the firmware to halt at memory training. Consult the motherboard manual for the exact population order before seating the four DIMMs.

Questions about this item

Should I pick the 384GB kit or a smaller capacity for my GIGABYTE MZ73-LM2?

The 384GB kit provides four 96GB modules that match the board's DDR5 4800 registered ECC requirements. Choose it when your workload needs maximum capacity and the manual confirms full-slot population at this density.

What does the 4800MHz rating actually deliver once installed?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V. The registered design lets all four slots operate at this rated speed when the motherboard memory controller is configured for full population.

How does the 288-pin RDIMM interface limit what I can do?

The 288-pin registered DIMM form factor fits only RDIMM slots on the MZ73-LM2. It cannot be used in UDIMM or SODIMM sockets, and the board's population rules determine which slots must be filled first.
