Target Workstation Memory

This 128GB DDR5 module is built for the ASUS Pro WS WRX90E SAGE SE motherboard, delivering registered ECC stability for professional workloads. It suits IT departments and workstation builders who need maximum capacity per slot in a validated configuration.

Registered Design and Pin Layout

The 288-pin RDIMM format uses a registered buffer to reduce electrical load on the memory controller, supporting dense 4Rx4 organisation without a heat spreader. Installation follows standard DIMM seating procedure on the qualified platform.

Capacity and Speed Decide Fit

A single 128GB stick running at 5600 MT/s with CL46 latency at 1.1V determines whether the board can reach its target memory density and bandwidth. Buyers needing lower latency or non-ECC operation should look elsewhere.
