Exact-match server upgrade

This NEMIX RAM module delivers 64GB of DDR5 ECC RDIMM memory rated at 4800MHz PC5-38400 with CL40 latency and 1.1V operation. The 2Rx4 registered design targets the GIGABYTE MZ73-LM0 motherboard for full-capacity recognition at rated speed.

Registered DDR5 population limits

Registered architecture offloads the memory controller to support fully populated slots at full capacity while ECC corrects single-bit errors on the fly. Your motherboard manual defines the maximum supported capacity per slot and the approved DIMM population order for this 288-pin form factor.

Verify board rules before ordering

Confirm the GIGABYTE MZ73-LM0 motherboard supports 64GB registered DIMMs and review the required installation sequence in the system manual. This kit is not compatible with UDIMM or SODIMM slots and requires a platform that accepts registered ECC DDR5 memory.

Questions about this item

Should I choose the 64GB 2Rx4 module or a different capacity for my GIGABYTE MZ73-LM0?

This exact-match kit is a single 64GB 2Rx4 Registered ECC RDIMM rated at DDR5-4800 CL40 1.1V. Consult your motherboard manual for approved DIMM population order and maximum supported capacity per slot before purchasing.

Will this DDR5-4800 CL40 module run at its rated speed once installed in the server?

Yes, the module is spec-matched to the GIGABYTE MZ73-LM0 memory controller so it is recognised at full 64GB capacity and operates at DDR5-4800 (PC5-38400) with CL40 timings at 1.1V without manual tuning.

What does the 288-pin Registered ECC interface mean for my GIGABYTE MZ73-LM0 motherboard?

The 288-pin RDIMM form factor is the only type the MZ73-LM0 accepts; registered buffering offloads the memory controller for full-slot stability, while on-die ECC corrects single-bit errors to prevent silent data corruption.
