NEMIX RAM 512GB (4x128GB) DDR5 4800MHz CL40 ECC RDIMM for ASRock IMB-1900/1902 memory upgrade

512GB DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 512GB of DDR5 4800 registered ECC memory in four 128GB modules. It is built for ASRock Industrial EATX motherboards IMB-1900 and IMB-1902. The 288-pin RDIMMs run at 1.10V with CL40 latency and 4Rx4 organisation. It targets servers and workstations that require maximum registered capacity with error correction.

Suited for IMB-1900 and IMB-1902 upgrades

This kit suits administrators expanding memory on the listed ASRock Industrial platforms where registered ECC DDR5 is required. It is not for consumer desktops or laptops that accept only unbuffered non-ECC modules. It is also not for systems limited to lower densities or different pin counts. Buyers needing unregistered memory should look elsewhere.

Four 128GB modules fill four slots

The 512GB total uses every available 128GB RDIMM in a four-module configuration. This provides high capacity for virtualisation, large datasets and multi-threaded workloads on the compatible motherboards. Headroom ends when all four slots are populated; further expansion would need a platform with more memory channels or higher-density modules.
