NUC8i7HVK with eGPU doesn't show login screen after the first boot

Hi,

 

I have an Intel NUC Hades Canyon NUC8i7HVK with a connected eGPU by Razer (Core X Chroma).

The eGPU contains a Nvidia GTX 1080Ti and is connected with a Thunderbolt cable which came with the eGPU. My two 28" monitors are connected to the eGPU with Display Port cables.

I never get the Win10 login screen displayed after I start the NUC for the first time at the day.

The NUC has bootet and the USB devices (mouse and keyboard) are connected - I can even hear the connecting sound, but the monitores are still dark.

I always have to push the power button until the NUC is switched off. Then I turn it on again and I got my Win10 login screen.

I don't have this problem, if I connect the two monitors directly to the NUC.

 

Windows 10 is installed and up to date. Every driver is installed and up to date.

Windows 10 Pro - 1903 - 18362.175

I have installed the App Thunderbolt Control Center from Microsoft Store. In the App the Razer Core X Chroma is set to "always connect".

 

What else can I do to get the login screen displayed normaly?

 

Thanks in advanced.

Have you updated the nuc bios?

Have you updated the nuc thunderbolt? https://downloadcenter.intel.com/download/28735?product=126143

 

Have you checked with the manufacturer of the eGPU?

What version of windows 10 are you running? 1903?

The Thunderbolt driver was up to date, already.

I just updated the BIOS, but it didn't solve the problem.

My Windows 10 Version: Windows 10 Pro - 1903 - 18362.175 - Windows updates says, that it has nothing newer.

I didn't contact the manufactor (Razer) of the eGPU, because the eGPU works fine with a friends notebook.

Hello Lakrimosa,

 

Thank you for posting on this Intel Community.

 

We recommend using the Thunderbolt™ 3 Controller Firmware Update Tool for NUC8i7HNK, NUC8i7HVK to make sure your unit is up to date. Please follow the instructions contained on the link below.

How to install

1. Download this driver package and unzip it to a folder on the Intel NUC.

2. Connect a Thunderbolt device to the Thunderbolt port.

3. Uninstall the existing Thunderbolt Software. This should also uninstall the driver.

  • Open the Start menu and click Settings.
  • Select Apps & features.
  • Select Thunderbolt Software and click Uninstall.

4. Open Device Manager by pressing the Windows key + X, then select Device Manager.

If the issue persists, please run the Intel® System Support Utility (Intel® SSU) and attach the report to this thread.

 

1. Download the Intel® System Support Utility and save the application in your computer.

2. Open the application and click "Scan" to see system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".

3. To save your scan, click Next and click Save.

I tried the described steps, but I can't install the Thunderbolt 3 Controller Firmware Update Tool, because of an error message.

Error: 0x208 SDK_SERVICE_NOT_FOUND Thunderbolt (TM)

service doesn't exist

 

My eGPU is still connected and running and I can use it (it has USB 3 slots, which are working, too).

I bought an Displayport switch 2>1 (2 devices to 1 monitor) and I connected the monitor I am using for games to that switch.

When I work, I have both monitors connected to the NUC and if I want to play a game, I press a button on the remote control from the switch and the gaming monitor is connected with the eGPU.

That works fine for me.

Hello Lakrimosa,

 

The error "0x208 SDK_SERVICE_NOT_FOUND Thunderbolt(TM) service doesn't exist" occurs when the Thunderbolt Bus Driver for your Intel® NUC is not installed.
