768GB DDR5-4800 ECC RDIMM kit for GIGABYTE MZ73-LM0

This 12-module kit delivers 768GB of DDR5-4800 registered ECC memory built to the exact specifications of the GIGABYTE MZ73-LM0 motherboard. Each 64GB module uses a 2Rx4 organization at 1.1V with CL40 latency. It is intended for server administrators who need maximum validated capacity on this specific platform.

Fits 12 DDR5 RDIMM slots on the MZ73-LM0 board

The modules use the 288-pin RDIMM form factor required by this motherboard and will not fit UDIMM or SODIMM slots. Registered buffering reduces electrical load on the memory controller so all twelve slots can be populated at full rated speed. ECC protection corrects single-bit errors in real time to prevent silent data corruption. No heat spreaders are included, so airflow across the DIMMs must be provided by the chassis.

Sustained enterprise workloads at full population

Registered architecture maintains signal integrity when every slot is occupied, allowing continuous operation at DDR5-4800 without downclocking. ECC correction runs transparently during long compute jobs, avoiding unplanned reboots caused by soft errors. The 1.1V operating voltage keeps power draw predictable across the full kit. Verify the motherboard manual for approved population order before installation.

Questions about this item

Will the twelve 64 GB modules run at DDR5-4800 CL40 when every slot on the GIGABYTE MZ73-LM0 is populated?

The kit is built to the exact rank, voltage and timing the board expects, so all twelve 64 GB RDIMMs operate at the rated 4800 MT/s CL40 without downclocking.

How much heat and power do twelve 1.1 V RDIMMs add in a continuously loaded server?

Each module draws 1.10 V with no heat spreader; total power scales with the 768 GB capacity, so plan airflow for the full 12-DIMM population.

What motherboard feature must already be present for this registered ECC kit to function?

The GIGABYTE MZ73-LM0 must support 288-pin DDR5 RDIMM slots with registered ECC capability, which this board provides.
