Gigabyte MZ31-AR0 Compatible DDR4

This 16 GB DDR4 3200 module is built for the Gigabyte MZ31-AR0 motherboard and AMD EPYC server platforms. It delivers registered ECC memory for workloads that require error correction and system stability.

Registered ECC DDR4 3200 constraints

The RDIMM format adds a register that buffers address and command signals, which limits maximum speed to the JEDEC 3200 MT/s rating. Mixed populations or higher frequencies are not supported by this module design.

16 GB capacity headroom

A single 16 GB stick suits entry-level virtualization, database caching, or file-serving roles. Larger datasets or heavy multi-tenant workloads will exceed this capacity and require additional modules.

Questions about this item

Should I pick the single 16 GB stick or look for a 2 x 8 GB kit?

The listing is for one 16 GB module (1X16GB). If your Gigabyte MZ31-AR0 has free slots you can add more identical sticks later to reach the capacity you need.

Will the 3200 MHz rating actually run at 3200 MHz on my EPYC board?

Yes, the module is rated DDR4 3200 (PC4-25600). On a compatible Gigabyte MZ31-AR0 it will operate at 3200 MHz provided the BIOS is set to that speed.

Does the RDIMM ECC design limit the usable speed on a Gigabyte MZ31-AR0?

The registered ECC RDIMM runs at the standard 1.20 V and CL22. The board's memory controller caps the final data rate, but the module itself is specified for the full 3200 MT/s.
