You need a proper Gen2 capable eGPU adapter like a PE4C V3.0 or PE4L 2.1b, both with soldered cables. EXP GDC fails Gen2, hence your BSOD and poweroff.

But I have PE4L 2.1b with soldered cables

Imho the -250mb show that there is a rather wrong space allocation for your egpu.. Do you experience a slower PC when egpu is connected in comparison to when it is not? 

 

If your laptop slows down, perform a dsdt override. That solved the issue for me. Also make sure to set PCI speed in BIOS to Gen1.

 

 

Thanks man! You are right, I felt slow down. I had problems with TOLUD and radeon hd5670, but updating bios repaired it, so I didn't thinking about dsdt anymore. But I just changed PCI Express in BIOS to GEN1 and it worked! Thank you again!

So there is no way I could have gen2? 

Hello Everybody!

I have problems too...

What I got:

Lenovo T520, i5 2520M, 16GB RAM

dgpu: NVS 4200M

egpu: GTX570 (tested on desktop)

PE4L 2.1b + 350W ATX

After purchasing PE4L I updated BIOS and happily connected to HD5670. Today I recovered my notebook to be sure nothing from radeon drivers left. And for few hours I'm trying to connect with my GTX570. I have no errors in device manager, Both, egpu and dgpu are visible, but still no signal on external monitor. I tried uninstalling dgpu and installing drivers in many combinations, with dgpu enabled, disabled, older drivers etc. And strangely CPU-Z is showing egpu like it shows dgpu without drivers (-250MB of memory). I wanted to try custom verde drivers but couldn't find custom nvam.inf file. Any help is appreciated. I was so happy to play some games this holiday  ...
