Hi, hound1013 I have read your post and the method is not work on my system ! my system: -Thinkpad X201 Tablet(i7 620, 8GB RAM, Integrated Intel HD) -COLORFUL iGame650Ti 2GB Using your method: power it up with the card plugged in, and pull it out right before the display comes up, Hotplug it at Windows environment. After completion, I installed NVIDIA display driver (ver 320.49) . I can not use eGPU, and the Device Manager shows the graphics card is GTX660, not GTX650. But using an external monitor, the system is working properly, Device Manager shows the graphics card is GTX650TI. Any help/instructions would be immensely appreciated. Thank you.
