I have an eGPU setup with a T460p Thinkpad and a GTX 560 and 1060. The NGFF.M2 slot I use is not hotplug enabled. However, the GTX 560 works perfectly fine with the new 376.33 driver, but the GTX 1060 gives error 43 with the same driver, and thus requires a rollback to 372.70 to work. Can anyone with a larger Nvidia graphics card collection find out where between the 560 and the 1060 cards drivers past 372.70 start to cause problems?

   

Its just 10-series cards that have problems. 376.33 is working fine with my 960.

 

Try installing 375.63 without uninstalling 372.70.

@Plastixx, I just tried this, gave me an error 43. Ah well.

@nando4, you mentioned in the original post that AMD cards do less than Nvidia when using a single lane. How much worse is it? I might end up returning my 1060 and buying an rx 480 if I (or anyone else) can't find a long-term solution to this driver issue.

I'd advise getting a GTX9xx series instead of an AMD card. They've been reported as not having this error 43 issue with newer drivers. NVidia outperforming AMD on x1 links AND offering Optimus to accelerate the internal LCD if have an active Intel HD iGPU. Compelling reasons to stick with NVidia on narrow x1 links.

hi,

i have a thinkpad x220 and i am using pe4c v3.0 expresscard with gtx1060.

372.70 working fine with internal LCD over optimus, but newer drivers gives error43.

notebook has modded bios and i activated hotplug enable option on all pci port.

so, i am not sure whether this problem is related with hotplug issue...

TL;DR: For Expresscard like in my HP 8760W, NVIDIA Driver Version 375.70 is the latest version that will allow an NVIDIA 10xx series eGPU to run without error 43.  Reason: Undetermined 

I'm having a similar issue and I found a way to get 372.90 (or newer) working.  I'm also using a GTX1060 (6GB Mini from ZOTAC)  I'm going to keep trying newer and newer ones and I'll keep updating here, but here's what I did:

  1. Use display driver uninstaller to delete all NVIDIA related video drivers, restart
  2. Install 372.90 (or newer) using NVIDIA installer, restart
  3. eGPU should work without Error 43 on boot, if not, try step 4
  4. Device Manager > Display Adapters and find a device that's called Standard VGA or similar, right click and "Update Driver" > "Browse" > "Let Me Pick" > "Have Disk" > "Browse" and browse to wherever you extracted the NVIDIA drivers (for me C:\NVIDIA\DisplayDriver\372.90\Win8_Win7_64\International\Display.Driver\nv_desktop_ref4i.inf), Open > OK > Choose your card's name (should be only one) and click next.  It should install, your screen should go blank for a bit and then the eGPU should kick on.

Versions Tested (* denotes verified working, ! denotes error 43 result): 372.70*, 372,90*, 373.06*, 375.63*, 375.70*, 375.95!, 376.09!

  • Can confirm gtx 1070 pe4c v3.0 via express card on a Thinkpad W530 i7-3740qm with Intel 4000 and the Nvidia Quadro K2000m works but only with the rollback 372.70 driver. I will look around for the hotplug option or listing in the bios and online. I'll also try to move up drivers one by one to see what happens. I would be up for possibly a hacked/modded bios to get around this issue if possible.

James, the expresscard interface is specced as being hotpluggable. Did you check whether  your eGPU hosting PCIe port (expresscard) is already hotplug enabled like shown on the opening post? Two posts up, @Velitacast managed to use 375.70 on his expresscard equipped HP 8760W.

So is this driver issue specific to Windows 10? Has anyone tried on Windows 7/8?

I cant install driver older than 375.95, because this isn't contains my dev and subsys ids. But newer drivers get error 43. Please help me to install older drivers...
