Verified on Lenovo Z570 laptop with EXP GDC adapter BEAST v8.x.

 

 

Key things:

  1. You need to disable the discrete graphics card (dGPU) in BIOS (otherwise if it loads with dGPU and eGPU on, I had a black screen because apparently the hardware conflict is with dGPU and eGPU)
  2. The PCI-E port to which the external video card (eGPU) is connected must be enabled Hot plug
  3. Installed Geforce driver version 375.63. (By the way the driver is
    This version is available from the manufacturer of my video card https://www.asus.com/Graphics-Cards/EX-GTX1050TI-4G/HelpDesk_Download/) Before installing the driver, remove the previous Geforce driver using DDU.

 

The order of inclusion is:

  1. The eGPU is turned off when the notebook is turned on.
  2. Insert the laptop into sleep and turn on the eGPU and remove the laptop from sleep.
  3. And eGPU The video card works.

I did not disable the Intel HD Graphics 3000 in the device manager. The driver version is 9.17.10.4229.

 

Problem: How to update (from the current working version 375.63) the Geforce driver without losing the work of the eGPU. Tried to roll over with the express installation version of the driver 378.92. And I received Error 43 error. I deleted Geforce driver (version 378.92) again in DDU and rolled back 375.63.

 

What I did next:
I did a DSDT override (I did it using the method from Microsoft) and then cast the resulting dsdt.aml in the config folder (which is stored in the root of the eGPU DIY Setup 1.35 image). In eGPU, DIY Setup performed PCI compaction setting in the range of 56.25GB - for eGPU - none. And then he went through the configuration instructions. Boot into Windows 10 (Enable eGPU before launching the laptop) and the eGPU runs without Error 12.

When you turn on the picture from the laptop I get to the monitor by D-SUB. After switching on, switch the signal source of the monitor from D-SUB to HDMI.
D-SUB displays the laptop screen. HDMI displays the picture from the eGPU.

It is difficult, but has not yet figured out how to automate it. And it can not be loaded blindly. It is necessary that the eGPU DIY Setup is loaded first (with the configuration loaded) and then you need to select the Windows 10 boot.

Note: By default, the boot loader loads eGPU DIY Setup

 

If interested, I will describe in more detail later how to put a Hot plug on the PCI-E port if this setting is not visible in the BIOS settings (but it's there).

 

Check out this method with your GTX 1050 and write about the results. 😉

I forgot to specify that the driver I set for desktop

I see you got your Lenovo setup to work.  If you don't mind, could you take a look at my post and offer any suggestions.  Thanks so much!

Did you manage to get smooth performance?

I also have a Lenovo z570 with i7 2670QM. Got the 1050ti working using this solution but the performance is quite bad. Using Window 10 Pro - 1709. When I minimize and then restore a full-screen window, it is jerky, not a smooth transition. Same thing when I scroll a webpage or watch a youtube video. Not to mention if I try to open OBS, it's pretty inoperable. Super laggy. 

In GPU-Z I have the exact readings like you.

Any advice?

Hi @xray

I tried following your instructions and managed to get Hotplug enabled on my WLAN PCIE port.

But even after booting with WLAN card and Hotplugging during sleep, my EXP GDC is not recognized.

If I boot with the GDC connected, then the port disappears (even though I'm using a Whitelist removed version of BIOS)

Is there something else I can try to debug?

Thanks in advance for your  excellent guide.
