Exact DDR5 RDIMM kit for GIGABYTE MZ73-LM1

This NEMIX RAM kit delivers 32 GB of DDR5 server memory in a matched pair of 16 GB modules. It is built for the GIGABYTE MZ73-LM1 motherboard and uses the 288-pin RDIMM form factor that board requires. Registered ECC operation keeps data integrity intact under continuous workloads.

Registered ECC with 1Rx8 organisation

Each module runs at DDR5 4800 (PC5 38400) with CL40 latency at 1.10 V. The 1Rx8 rank layout and registered buffer match the memory controller expectations for full-capacity recognition. ECC corrects single-bit errors on the fly to prevent silent data corruption.

Suited for MZ73-LM1 upgrades.

This kit suits administrators expanding a GIGABYTE MZ73-LM1 with validated registered ECC memory. Builders needing UDIMM, SODIMM or non-ECC modules should look elsewhere because the board will not accept those form factors.

Questions about this item

Will the DDR5-4800 speed run at its rated 4800 MT/s on the GIGABYTE MZ73-LM1 motherboard?

Yes, the kit is an exact-match upgrade for the MZ73-LM1, so the memory controller recognises the 1Rx8 registered ECC modules at full capacity and operates them at the rated DDR5-4800 (PC5-38400) speed with CL40 timings.

Does the registered RDIMM interface limit how many modules I can populate on this board?

The registered architecture offloads the memory controller, allowing every supported slot to run fully populated at full capacity, but you must follow the motherboard manual for approved DIMM population order and maximum capacity per channel.

Will these 288-pin RDIMMs fit the memory slots on the GIGABYTE MZ73-LM1?

Yes, the 288-pin DDR5 RDIMM form factor matches the slots the MZ73-LM1 requires; it is not a UDIMM or SODIMM, so the modules seat directly in the board's DDR5 DIMM sockets.
