Capacity 512GB (4 x 128GB)

  • 512GB total capacity from four 128GB modules
  • DDR4 3200 speed with CL22 latency for server workloads
  • ECC registered design detects and corrects memory errors
  • 2V operation reduces power draw in dense configurations
  • Built with major OEM chips from Samsung Micron Hynix

Capacity and Configuration

This NEMIX RAM kit delivers 512GB total capacity across four 128GB modules for DDR4 server platforms. The registered ECC RDIMM design targets enterprise workloads that demand data integrity and large memory footprints.

Who This Suits and Who Should Look Elsewhere

System builders outfitting compatible DDR4 servers or workstations with registered memory support will match the 3200 speed and CL22 timing. Buyers whose platforms require unbuffered UDIMM modules or a different DDR generation cannot use this kit.

Installation Notes

The 288-pin RDIMM form factor fits standard DDR4 server slots and operates at 1.2V without extra configuration. Installers must verify that the motherboard accepts 4Rx4 registered modules and supports the full 512GB capacity, otherwise the system may fail to post.

Questions about this item

Does my server motherboard need 288-pin DDR4 RDIMM slots that support 4Rx4 modules to use this kit?

Yes, the kit requires 288-pin DDR4 RDIMM slots and the motherboard must support 4Rx4 registered ECC modules at 1.20V.

Can I mix these 128GB 4Rx4 modules with existing 2Rx4 or 2Rx8 DDR4 3200 RDIMMs in the same server?

Mixing ranks is not recommended; the memory controller will typically downclock or disable channels to maintain stability.

How can I verify the kit is running at DDR4 3200 CL22 with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm speed 3200 MT/s, CAS 22, voltage 1.20V and ECC enabled.
