@carage, I've had several users report success via email of circumventing this error 43 issue by downgrading to a GTX9xx card. It is advised you carefully read the opening post of this thread to see if you can either enable a PCIe port hotplug bit or use a driver workaround to resolve the error 43 before doing the downgrade from your GTX1080.
I am considering to replace my GTX 1080 with a second-hand GTX 980 Ti,
just want to seek confirmation that this issue does not affect the GTX 900 series before I make an overpriced downgrade.
Can anyone confirm whether GTX 900 cards won't run into this driver limitation?
Thanks in advance.
And what happened? As far as i remember, you had successfully installed new drivers via 368.81 here. Why did you decide to change your card?
If you never ask, then you will never learn

It appears my Express Card slot already has hotplugging enabled by default but it is still affected.
I also tried the driver workaround, but the newer drivers keep creating new problems so I still end up reverting back to 375.70.

Too bad 1060 is released 1 month later2 days after 368.81 driver was released. I have hotplug enabled yet get same error 43 when I try to install newest drivers.
Got it working and updating my implementation post right now.
Steps to get it working:
Forgot to mention but modded drivers will only install under test mode. Some people reported that disabling integrity checks didn't work for them.
bcdedit -set TESTSIGNING ON
Download368.81 drivers.
Unpack exe with 7zip(or similar software).
Go to Display.Driver and open up nv_dispi.inf
Add 1 line%NVIDIA_DEV.1c02% = Section062, PCI\VEN_10DE&DEV_1C02 (where 1c02 is dev id of your gpu) after%NVIDIA_DEV.1C03% = Section062, PCI\VEN_10DE&DEV_1C03
Add 1 lineNVIDIA_DEV.1C02 = "NVIDIA GeForce GTX 1060 3GB" (dev id and your card title) afterNVIDIA_DEV.1C03 = "NVIDIA GeForce GTX 1060 6GB"
Win10 c/o offline user
There is another step to force the installation of the inxftw's 368.81_modded driver. That is to force the installation of unsigned drivers when hash problem is found. The solution is from with Administrator command prompt run this:
and reboot. The notebook does have the mPCIe eGPU port hotplug bit disabled as show below.
Win7 c/o shoes
Got it working was holding Shift and clicking Restart > Advanced Startup > Troubleshoot > Advanced options > Startup Settings > 7) Disable driver enforcement
Then install the modified version and right after that install the latest version. Restart and voilla.
Save, and followIgorGIV guide.
For Win7
tried the inxftw/IgorGIV/offline solution in your forum:
hp elitebook 2570p + dsdt override via diy egpu setup 1.35 + expresscard exp gdc beast v8.4d + gtx 1050 ti + nvidia driver 385.41
edited nv_dispi.inf for the windows 7 (64 bit) driver a little differently:
has a few seperate blocks of device lists for win vista/7/8/8.1. put it under the win7 block "[NVIDIA_Devices.NTamd64.6.1]" last line, "%NVIDIA_DEV.1C03% ...", said "Section032" instead "Section062", changed my added line to "Section032" edited my dev id as "1C82" and card title as "NVIDIA GeForce GTX 1050 Ti"
just tried prey on the internal screen with no worse performance than before using the nvidia driver 375.70. calling it a success
nando4>> an offline user with a GTX1050Ti explained need a step 5.5 inserted between the above step 5 and 6:
Dear Nando, I finally make the 1050Ti works. Yes, I am the first in the world. I did it. I'm using an external monitor on the 1050 ti.

INFO: Potential fix for error 43 on GTX1050 and new GTX1060 cards
Requesting an error 43 affected GTX1050 or late GTX1060 user with a non-hotpluggable interface to test inxftw/IgorGIV/offline users fix in the previous post.
The offline user had a GTX1050Ti working on a non-hotplug mPCIe2 interface but his system's NVidia GT740M dGPU may mean it's a false positive.
