NEMIX RAM
A 64 GB DDR4-3200 ECC registered DIMM for compatible server motherboards
This 64GB DDR4 3200 MHz registered DIMM delivers error-correcting code memory for server and workstation platforms. It operates at 1.2V with CL22 latency and a 2Rx4 rank configuration. The 288-pin module is built with major OEM chips from Samsung Micron or Hynix. It targets IT professionals upgrading compatible Hynix-based systems.
This module fits servers and workstations that accept DDR4 3200 PC4-25600 registered ECC RDIMMs. It is not for desktop boards that require unbuffered non-ECC memory. It is not for platforms limited to lower densities or speeds. Buyers needing multiple ranks per channel beyond 2Rx4 should verify motherboard qualification lists.
The decisive specification is the 64GB density in a single 2Rx4 registered ECC RDIMM running at DDR4 3200. This combination determines whether the memory slot population and channel limits of the target server are met. Verify the system qualified vendor list for this exact part number MR25600-924K1 before purchase.

Yes, the module is a 64GB DDR4 3200 ECC Registered RDIMM. It must be installed in a server or workstation board that accepts registered ECC DIMMs; standard desktop boards will not recognise it.
Mixing ranks is often possible if the motherboard supports mixed-rank populations, but the system will run at the slowest common timing. Check the server manual for approved rank combinations per channel.
Enter the BIOS or UEFI and verify the memory speed shows 3200 MT/s (PC4-25600) and that ECC status reports enabled. Operating-system tools such as dmidecode or CPU-Z will also report 64GB, 2Rx4, CL22 and ECC active.
