Exact-match server upgrade

This NEMIX RAM kit delivers 128GB of DDR4 3200MHz registered ECC memory in two 64GB modules. It is built for the Supermicro X12DPFR-AN6 motherboard and matches the board's required 2Rx4 rank, 1.2V voltage and CL22 timing so the system recognises full capacity at rated speed.

Simple DIMM installation

The 288-pin RDIMM form factor seats like any standard server DIMM; align the key notch, press firmly until the retention clips click and the module is locked. Errors usually come from mixing registered and unbuffered DIMMs or populating slots in the wrong order, which the motherboard manual specifies.

Verify motherboard rules first

Check the Supermicro X12DPFR-AN6 manual for maximum supported capacity per socket, approved population sequence and any BIOS version requirements before ordering. This kit is not for systems that only accept unbuffered UDIMMs or SODIMMs, or for boards limited to lower densities or different voltages.

Questions about this item

How can I confirm the 128GB kit is running at DDR4 3200MHz CL22 after installation?

Check the BIOS or UEFI memory information screen; it should report 3200MHz speed, CL22 latency, 1.20V voltage and the full 128GB capacity with ECC registered mode active.

What is included in the MR25600-924K2 package and do I need any extra parts?

The box contains two 64GB 288-pin DDR4 RDIMM modules for a total of 128GB; no cables, heat spreaders or additional components are required for installation.

Should I choose this 2x64GB 2Rx4 kit or a different capacity for my Supermicro X12DPFR-AN6?

This 128GB 2x64GB 2Rx4 registered ECC kit matches the motherboard's DDR4 3200MHz PC4-25600 specification; consult your system manual for approved population rules and maximum supported capacity before selecting an alternative.
