Exact-Match Server Memory Kit

This NEMIX RAM kit delivers 128GB of DDR5 4800 memory as two 64GB Registered ECC RDIMMs. It is built to the precise 2Rx4 rank structure, CL40 timing, and 1.10V voltage that the GIGABYTE MZ73-LM0 motherboard expects for full-capacity recognition at rated speed.

Registered ECC Architecture

The registered design buffers address and command signals so the memory controller can drive a fully populated configuration without signal degradation. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned downtime in production workloads.

Verify Platform Population Rules

Server memory support varies by specific model and BIOS revision. Consult the GIGABYTE MZ73-LM0 manual for approved DIMM population order, maximum supported capacity per slot, and required installation sequence before ordering this 288-pin RDIMM kit.

Questions about this item

Will the 1.1V voltage or CL40 timing on these DDR5 modules change as the kit ages?

The 1.10V operating voltage and CL40 CAS latency are fixed electrical specifications of the DDR5 RDIMM design; they do not drift with age, so no recalibration or voltage adjustment is needed over the module's service life.

What limits sustained throughput first on the GIGABYTE MZ73-LM0 with this 2Rx4 registered ECC kit?

The memory controller on the MZ73-LM0 and the DDR5-4800 (PC5-38400) data rate set the maximum sustained bandwidth; the 2Rx4 registered architecture keeps every slot at full speed, so the controller's peak transfer rate is the first ceiling you reach.

How much extra heat or power does the 128GB kit add when the server runs 24/7?

Each 64GB DDR5 RDIMM runs at 1.10V without a heat spreader, so total power draw stays at the DDR5-4800 spec level; the registered buffer reduces controller load, keeping thermals comparable to smaller registered kits under continuous operation.
