NEMIX RAM 256GB (4x64GB) DDR5 4800 CL40 ECC RDIMM for ASUS Pro WS WRX90E SAGE SE memory upgrade

Capacity and Compatibility

This 256GB kit provides four 64GB DDR5 ECC RDIMM modules built for the ASUS Pro WS WRX90E SAGE SE workstation. Registered buffering and error correction protect data integrity in multi-threaded professional workloads. The modules run at 1.10V with a CL40 latency profile. Buyers who need non-ECC memory or consumer UDIMM form factors cannot use this kit.

Sustained Load Behaviour

Under continuous operation the registered design reduces electrical load on the memory controller, helping maintain stability during long render or compute sessions. ECC circuitry detects and corrects single-bit errors without halting the system. The 4800 MT/s data rate delivers consistent throughput for memory-bound server applications. Workloads that demand higher frequencies or lower latencies will not reach their targets with these specifications.

Installation Notes

Each 288-pin RDIMM seats in the standard DDR5 slots of the validated motherboard; no heat spreader is fitted, so clearance is minimal. The motherboard manual should be followed for population order to enable quad-channel operation. Mixing these modules with different capacities, ranks or voltages will prevent the system from posting. Buyers who cannot access the firmware memory-training logs may find troubleshooting difficult.
