Likely related to you using a PE4L 1.5b on a Gen2-capable X220. That product requires that you downgrade the pci-e expresscard link to Gen1 in the bios for reliable operations. Remko78 gives an example of a Gen2 X220 solution at http://forum.techinferno.com/diy-e-gpu-projects/4532-portable-low-profile-egpu-setup-lenovo-x220-pe4l-2-1b-case.html

You are correct, changing the expresscard link to Gen 1 fixed the problem. Thanks very much!

Hello,

I'm having trouble with my egpu setup:

Problem Description

The device manager says that the egpu is working, but the external lcd doesn't respond and the nvidia control panel won't open (it doesn't detect the egpu).

Platform Description

Windows 7 64bit

Lenovo x220

6gb memory

egpu: gtx 560 ti; igpu intel HD 3000

CX 500W power supply

PE4L ver 1.5

I have tried using the default drivers Win 7 installs as well as downloading version 320.49 desktop drivers from Nvidia; the problem persists in both cases. Advice would be appreciated!
