Server-grade DDR4 module

This 16GB DDR4 3200 ECC RDIMM is built for Gigabyte MZ32-AR0 motherboards running AMD EPYC processors. Registered buffering and error-correcting code protect data integrity in multi-socket server workloads.

Registered 288-pin form factor

The module uses a standard 288-pin RDIMM layout with 2Rx8 organisation and no heat spreader. Registered signalling reduces electrical load on the memory controller, allowing higher capacities per channel in dense server chassis.

Low-voltage DDR4 operation

Rated at 1.20V with CL22 latency, the stick draws minimal power while maintaining 3200 MT/s throughput. Passive cooling is sufficient in typical server airflow, keeping acoustics low in rack environments.

Questions about this item

What throughput ceiling does the DDR4 3200 PC4-25600 interface impose on this module?

The DDR4 3200 PC4-25600 standard sets the peak transfer rate at 25600 MB/s, which is the practical ceiling for this 16 GB 2Rx8 module.

What physical slot and clearance does the 288-pin RDIMM need on the Gigabyte MZ32-AR0?

It requires a standard 288-pin DDR4 DIMM socket; the module has no heat spreader, so low-profile clearance is not an issue.

What is the correct installation sequence for this registered ECC DIMM, and which step is most often missed?

Power down, open the chassis, align the notch with the keyed slot, press firmly until both retention clips click, then enable ECC in the BIOS — the BIOS step is the one most often skipped.
