@wmilun

Thank you for sharing you details. Here is what I think/did:

 

Overheating:

- I got Thermal Grizzly Carbonaut. One pad sufficed for GPU and CPU. I used to use Cryonaut but the pad is far better as it is easy to put on, will last longer AND works with low amount of pressure.

- I onstalled Throttlestop and untervolt your CPU to about -125mV on Core and Cache.

 

Unpluging:

- I simply do not hotplug my notebook to TB3 because of the externel stroage that is connected to my Chroma.

- I have my GTX 1650 deactivated in Bios unless I want to "game on the go".

 

Crash on Startup:

- I disabled fastboot and "Use my sign-in options to automatically setting up my device" under Win 10 -> Settings -> Sign-in options -> Privacy 

- The most chrashes on Startup where due to my impatience. Having strapped HDDs (bitlocked) & Bluetooth Mouse and Keyboard to the Chroma will result in longer booting times - especially with a clean restart or the restart after repluging my notebook.

 

Best regards

Hi all,

I recently got this laptop, a c940 i7 model with 12gb of ram and a 1080p display. I got it for other reasons other than its thunderbolt capability, however I wanted to look into using it as a desktop replacement. I got a gigabyte 1050ti gaming box that worked previously with another laptop I had, however i can't get it to work with this one.

the first time I (hotplugged) it in, it was recognized and the mouse I had plugged into it was recolonized as well.

I then went to download the thunderbolt drivers and update the thing, however now it isn't working at all.

I know both the ports work bc I can charge with them and have a usb-c doc that works as well. However, all the egpu does now is charge the laptop. I'm stuck. Do you guys have any advice?

 

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

First of all: If you have the model with GTX 1650 inside as I do, then I guess you will not benefit from the GTX 1050ti.

As to the reconigtion: I had this in the begining...

- be sure to disable fastboot/quickstart in Windows options and perform a fresh reboot. This helps in the most cases.

- you could as well uninstall the TB drivers completely and let windows do the job. It should install the drivers correctly.

Hope this helps!

All the best
