Compatible EPYC Server Memory

This NEMIX RAM module is an 8 GB DDR4 3200 ECC RDIMM built for the Gigabyte MZ31-AR0 motherboard. It runs at 1.20 V with CL22 latency and uses a registered 1Rx8 layout on a 288-pin PCB. The part number is MR25600-818K1.

Suited for registered ECC slots only

The stick fits servers and workstations that require registered ECC DDR4 memory on the specified Gigabyte platform. It will not work in systems that accept only unbuffered non-ECC modules or that use a different DDR generation.

Single 8 GB module headroom

One module adds 8 GB of registered ECC capacity at 3200 MT/s for typical server workloads. Larger memory configurations need additional identical RDIMMs to scale beyond this single module.

Questions about this item

What motherboard must already be installed for this MR25600-818K1 registered DIMM to function?

This module is validated for the Gigabyte MZ31-AR0 motherboard designed for AMD EPYC processors, so that board must be present.

Can this CL22 1Rx8 registered DIMM share a channel with older DDR4 registered modules already in the server?

Mixing speeds or ranks on the same channel is not recommended; the motherboard will clock all modules to the slowest common speed and may disable ECC if configurations differ.

How can I confirm the module is running at PC4-25600 with ECC active after installation?

Enter the BIOS or use a hardware information utility to verify the memory speed reads 3200 MT/s and that ECC status shows enabled for the installed DIMM.
