HP Elitebook + Razer Core X + Gigabyte RTX 2080 Ti -> Freezing during boot  

@adam_laita, 

I apologise but I am not too familiar with the BIOS setup of HP.

Does it have a section in relation to how it treats Thunderbolt devices upon boot?

Dell has a section that it can actually ignore anything connected to the Thunderbolt ports during post or can adopt them fully during. For me the full adoption during post allowed me to stop swapping inputs on my monitor from a connection to the iGPU to the eGPU.

I can dig out the Dell options as an example if it helps when I next boot my machine if it can assist in any way.

In my first topic - I've tried maybe every option in BIOS so I'm afraid that won't be working. As @itsage wrote it looks like problem in RTX 20XX itself. 

@adam_laita, Certain RTX graphics cards have firmware compatibility with the laptops and would cause boot hang when doing cold-plug. I haven't found a way around it. Fortunately Nvidia eGPUs can work through hot-plug in Windows so it's not that big of a deal.

@itsage, Hi Sage, do you have any information about compatibility with new RTX graphics 3XXX? Have the same problem as the previous model line? I sold the RTX 2080Ti and now I'm looking for a new graphic card and I'm deciding between NVIDIA RTX 3XXX or Radeon RX 6XXX.

@adam_laita, The RTX 3080 seems to behave better with cold plug. It has been working very well with my 2020 13-in MacBook Pro. I would set the Boot Camp volume as default source, connect the RTX 3080 Gaming Box, hit the power button and Windows loads up fine with eGPU fully functional.

@itsage, ok thanks for info, sounds good. 

I would try updating your bios. My 840 G5 had a bios update that fixed all my issues with my 2070 and boot issues. 

For me it was this version: 01.08.01 Rev.A

And the fix: - Fixes an issue which causes the system to power on slower than expected when an NVIDIA GeForce RTX 2070/2080 Graphics card is installed on the system.

they also fixed an issue with this laptop and Apples XDR monitor (which I might add works great lol)

@se12897, interesting do you know when it was released? According to HP support for my model last update is 01.07.02 Rev.A released on 6th November.

@itsage, so I've finally bought RTX 3070 and it's working normally so thanks for help 🙂

@adam_laita ,pls consider completing a build template and submitting a build to give your Elitebook X360 830 G6 some eGPU representation.
