NEMIX RAM 8GB DDR4 3200 ECC RDIMM

This 8GB DDR4 3200 ECC registered DIMM is built for the Supermicro H12SSW-NT motherboard. It targets administrators expanding memory in AMD EPYC-based servers or workstations that require registered error-correcting modules. The single-rank 1Rx8 organisation and 1.2 V operation match the platform's registered memory requirements.

Installation and common issues

The 288-pin RDIMM installs in the standard DDR4 slots of the H12SSW-NT board; no special tools are required beyond opening the chassis and seating the module until the retention clips latch. Because the module is registered, it must be used in slots designated for registered memory and cannot be mixed with unbuffered DIMMs. A frequent mistake is populating slots in the wrong order — consult the motherboard manual for the approved population sequence.

Who this suits and who should look elsewhere

This module suits IT professionals adding capacity to a verified Supermicro H12SSW-NT system where ECC registered memory is mandatory. It is not appropriate for builds that need unbuffered non-ECC DIMMs, for platforms that only support DDR5, or for buyers who require higher-capacity sticks than the 8 GB provided here.

Highlights

Questions about this item

How can I verify the DDR4 3200 module is running at PC4-25600 speed after installing it in the Supermicro H12SSW-NT?

Enter the BIOS and confirm the memory speed reads 3200 MT/s with CL22 timings at 1.20 V; the EPYC memory controller will show 1Rx8 registered ECC operation for the 288-pin RDIMM.

What comes in the package and is anything else required for the Supermicro H12SSW-NT?

The box contains one 8 GB DDR4 3200 CL22 1.20 V 288-pin ECC RDIMM (part MR25600-818K1); no additional parts or cables are needed for installation.

Which capacity should I choose for the Supermicro H12SSW-NT if I want registered ECC DDR4 3200?

This listing is the 8 GB 1Rx8 registered ECC RDIMM (MR25600-818K1); select it when you need a single 8 GB DDR4 3200 module for the H12SSW-NT.
