Exact DDR5-4800 ECC RDIMM

This 16 GB DDR5-4800 (PC5-38400) registered ECC module is built for the GIGABYTE MZ73-LM0 motherboard. It runs at 1.10 V with CL40 timing in a 1Rx8, 288-pin RDIMM form factor. The registered buffer and on-die ECC suit server workloads that require data integrity and full-slot population.

Registered buffer eases controller load

The registered architecture offloads the memory controller so every slot can run fully populated at rated speed without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots. The module fits only boards that accept 288-pin DDR5 RDIMMs and follow the MZ73-LM0 population rules.

Low-voltage DDR5 thermals

Operating at 1.10 V keeps power draw modest and heat output low in normal server use. No heat spreader is fitted, so airflow across the bare PCB is sufficient for typical chassis cooling. The DDR5 voltage regulation on the module itself reduces load on the motherboard VRM. Buyers needing higher capacities per slot or non-registered UDIMMs should look elsewhere.

Questions about this item

Does the 1.1 V operating voltage and lack of a heat spreader limit sustained throughput on the GIGABYTE MZ73-LM0?

The module runs at the standard 1.1 V for DDR5 4800 RDIMM; registered buffering reduces electrical load on the memory controller, so thermals stay within normal server limits even without a spreader.

What is the acoustic and thermal profile when the RDIMM runs continuously in a fully populated server?

Registered ECC RDIMMs have no moving parts; the 1.1 V design and registered architecture keep power draw low, so fan noise and case temperatures remain at typical server-idle levels.

Which motherboard and memory population rules must already be in place for this 16 GB DDR5 4800 CL40 1Rx8 RDIMM to function?

A GIGABYTE MZ73-LM0 motherboard with DDR5 RDIMM slots, correct DIMM population order per the board manual, and a CPU that supports registered ECC memory are required.
