You need more info about my computer ? I need help for increase bus interface See U Put the eGPU under load and then observe if the Bus Interface field in GPU-Z changed from x1 1.1 to x1 2.0. If yes, then your port already runs at Gen2 speed and just reverts to Gen1 for power management. If not, then use Setup 1.30 to change your eGPU port to Gen2 speed.
