NEMIX RAM
A 96 GB DDR5 registered ECC server module running at 4800 MT/s with CL40 latency and 1.1 V operation
This 96 GB DDR5 4800 module delivers registered ECC memory for compatible server and workstation platforms. The single 2Rx4 rank stick operates at 1.10 V with CL40 latency and fits 288-pin RDIMM slots. It targets IT professionals who need high-capacity, error-correcting memory for mission-critical workloads.
The registered buffer reduces electrical load on the memory controller, helping stability during continuous multi-threaded tasks such as virtualisation, database serving or large-scale rendering. ECC corrects single-bit errors on the fly, preventing silent data corruption over long uptimes. Testing under load is performed by the supplier to verify reliability before shipment.
Without a heat spreader the module relies on chassis airflow, running at the standard 1.1 V DDR5 voltage for efficient power draw. Passive operation adds no acoustic noise, making it suitable for dense rack environments where fan speed is managed by the system. The low-voltage design helps keep per-module heat output modest under typical server workloads.

The module operates at 1.10V, the standard DDR5 voltage, so power draw scales with the 4800 MT/s data rate and 96GB density; actual watts depend on workload and motherboard voltage regulation.
A server or workstation board with DDR5 RDIMM slots, registered-memory support and ECC enabled in the BIOS is required; standard consumer DDR5 boards without registered-DIMM support will not work.
Yes, provided every installed module is DDR5 ECC registered, the memory controller can train each rank at 4800 MT/s CL40; mixed capacities are supported but total per-channel rank limits still apply.
