Ok thanks ... this is really nice to find help here, not really easy to do that alone, so if i can help someone who has the same config than me, i will be proud to try.

Some Studio XPS 1640 are already listed on the first post @x4, but if you insist i can give you all the details of my config, But please, just tell me if it will be usefull to PCI compress my config even everything works well without using it.

Hello everybody, Can I get an explanation about what's the use of a PCI Compaction ? I've got a PE4H with a GTX-560 Ti connected on a Dell Laptop, The eGPU is @x2, and everything works nicely without PCI Compaction.

So, it tried both, and the problem is different now ... after Retrain, Windows does not recognize the eGpu ... I don't really understand why, because AIDA64 and GPU-Z they recognize it. So i restarted Windows, and after that the eGpu is recognized. But the problem still happening when i switch between the iGpu (ATI) and the eGpu (NVIDIA).

OK Thanks, i will try this this afternoon.

Hello, i've got a PE4H v 2.4a which is used to connect an Nvidia GTX-560 Ti to a Dell Studio XPS 16 with a x1700 ATI onboard. the connection is with one lane on a x1 mPcie without any problem. The problem appears when i try to connect 2 lanes, i use the program Setup 1.x to switch the MPcie port number 3 to x2, port number 4 is used to connect the second lane by express card. When i start Windows everything is fine, while i use the integrated graphic card, fine ... i can see on AIDA64 that my Nvidia is recognized as x2 peripheral. When i switch to the nvidia, black screen ... BSOD. Does anyone has an Idea where i should looking for to resolve this issue ?
