  • 288-pin RDIMM form factor fits the GIGABYTE MZ73-LM0 motherboard

Exact-match server kit

This 128GB kit delivers four 32GB DDR5 modules rated at 4800MHz PC5-38400 with CL40 latency and 1.1V operation. The 2Rx8 registered ECC RDIMM design matches the GIGABYTE MZ73-LM0 motherboard requirements so the system recognises full capacity at rated speed.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller, allowing all four slots to remain fully populated at 4800MHz without down-clocking. ECC corrects single-bit errors in real time, preventing silent data corruption during continuous server workloads.

Pre-order checklist

Verify the motherboard manual for approved DIMM population order and maximum supported capacity per slot. Confirm the board requires 288-pin registered RDIMMs rather than unbuffered or SODIMM alternatives before installation.

Questions about this item

Does the 1.1V operating voltage of these DDR5 RDIMMs keep heat and power draw manageable under continuous server loads?

Each module runs at 1.1V with no heat spreader, relying on the GIGABYTE MZ73-LM0's airflow design to dissipate heat while the registered architecture reduces electrical load on the memory controller during sustained operation.

What motherboard and form-factor requirements must my system meet to install this 288-pin DDR5 RDIMM kit?

You need a GIGABYTE MZ73-LM0 motherboard with DDR5 4800 RDIMM slots that accept 2Rx8 registered ECC modules; UDIMM or SODIMM slots will not work, and the board must support four DIMMs populated at 128GB total capacity.

Can I mix these CL40 2Rx8 DDR5 RDIMMs with existing DDR5 modules of different rank or speed on the same GIGABYTE MZ73-LM0 board?

Mixing ranks or speeds is not recommended; the board's memory controller expects identical 2Rx8 DDR5-4800 CL40 registered ECC modules in the validated population order to run all four slots at the rated 4800MT/s without downclocking or stability issues.
