16 GB DDR4 3200 ECC registered RDIMM for Gigabyte MZ01-CE0 EPYC servers
This 16GB DDR4 3200 module is built as a registered ECC RDIMM for Gigabyte MZ01-CE0 motherboards running AMD EPYC processors. It operates at 1.2V with CL22 latency and uses a 2Rx8 organisation across 288 pins. The module is validated for server workloads that require error correction and registered signalling.
The single 16GB stick suits administrators who want to add one registered ECC module to a compatible Gigabyte EPYC platform. Builders who need unbuffered UDIMMs, non-ECC memory, higher frequencies or lower latencies should look elsewhere.
Verify that the MZ01-CE0 accepts a 2Rx8 registered DIMM in the target slot and that the BIOS revision supports DDR4 3200 at 1.2V. Confirm the channel population order required by the EPYC CPU before installing the 288-pin module.

Yes, the board is an AMD EPYC server platform that only accepts registered ECC RDIMMs, and this module matches that requirement exactly.
The memory controller will downclock all modules to the speed of the slowest installed DIMM, so mixing is possible but overall bandwidth will drop.
Check the BIOS memory information screen or run a tool such as dmidecode; it should report 3200 MT/s, CL22 timings and ECC enabled for the DIMM.
