Trouble with Quadro RTX in laptop and 1080ti eGPU

Recently got a new laptop to use as a desktop replacement with the express intention of using it with a 1080ti eGPU for games at night. Ive since run into a problem with drivers. Nvidia will not allow the use of both cards, if I install the geforce drivers to make the eGPU work it kills the drivers(windows code 43) for the built in card (RTX4000 mobile). i first thought this isnt a big deal i dont need that extra card while im hooked up but no, it even leaves it disabled after I disconnect the eGPU leaving me with just intel graphics. has anyone dealt with a similar problem and got around it?


Thank you for any insight!

Goal setup: Lenovo P73 i9, RTX4000m wanting to add GTX1080ti eGPU

Hi man,

Are you able to manually enable it again in Device Manager without de eGPU connected? This way you could just disable it when using the eGPU (also provides more stability). And enable it again when you don't use the eGPU. I know this is extra work but it should fix your problem.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@gage_lindell, Look at my guide for the ThinkPad P52. It uses an older Quadro card (P3200) but the instructions should still work for your needs.
