NEMIX RAM
32 GB DDR5-4800 ECC registered server module at 1.1 V with CL40 latency
This 32 GB DDR5 module is built for registered ECC server and workstation boards that require Hynix-compatible RDIMMs. It targets IT teams upgrading capacity in mission-critical systems where data integrity and stability come first.
The module runs at the standard DDR5 4800 speed with CL40 latency while drawing only 1.10 V. Registered buffering reduces electrical load on the memory controller, helping thermals and power draw stay predictable under sustained workloads.
Dual-rank x8 layout fits a single DIMM slot without a heat spreader, keeping height low for dense chassis. Buyers needing unbuffered UDIMMs or non-ECC memory for consumer boards should look elsewhere.

Align the notch on the module with the slot key, press firmly until both retention clips click, and ensure the system requires registered ECC memory before purchase.
No scheduled maintenance is required; if errors appear, run a memory diagnostic and replace the module if it fails testing.
The CAS latency of 40 cycles and fixed 1.10 V voltage set the performance ceiling during prolonged workloads.
