NEMIX RAM
32 GB DDR5-4800 ECC registered RDIMM, CL40 2Rx8 at 1.10 V for Hynix-compatible servers
This 32 GB registered DIMM runs at DDR5 4800 with CL40 latency and 1.10 V operation. It targets IT professionals who need error-correcting memory for mission-critical server or workstation deployments. The module uses Hynix-compatible 2Rx8 organisation and carries ECC and registered buffering for data integrity.
Installation requires a server or workstation motherboard with a 288-pin DDR5 RDIMM slot and registered memory support. The single 32 GB stick occupies one slot, leaving remaining channels free for future capacity expansion. No heat spreader is fitted, so airflow across the bare PCB must be provided by the chassis.
At the standard 1.10 V the module draws minimal power and runs cool under typical server workloads. The absence of a heat spreader means thermal performance depends on case airflow directed over the memory banks. Registered buffering and ECC add negligible acoustic contribution.

CL40 is the rated CAS latency at DDR5 4800; sustained throughput depends on the server platform and memory controller.
The module operates at 1.10V with no heat spreader; thermal output is managed by the server chassis airflow.
A DDR5 RDIMM slot supporting ECC registered memory is required for this 288-pin module.
