Razer Blade Stealth+Core X "Functionality Limited"
When I plug it in the fans on the eGPU start up and turn on and I get a message on the Blade saying "Thunderbolt device functionality might be limited" with a link to a Microsoft site. I follow all the instructions on there to no avail. In device manage the Core appears in the Universal Serial Bus Devices section however nothing appears in the Display Adapters Section.
I have tried other known working graphics cards, specifically an R9 380x with the same result. The Blade has the newest RTX 2060 drivers installed already. I have the most up to date version of Thunderbolt Control Panel. My Windows is up to date along with every driver I can find. The only thunderbolt drivers I can find on the Razer website are for the early 2019 models so I've tried to install those and gotten a message saying "Processing inf : TbtHostControllerExtension.inf
Failed to install the driver : No more data is available" in an attempt to combat the inf issue I tried to install that driver again in Test Mode and go the same result. I have tried to install Razer GPU switcher, however it won't open. I have done the reset procedure for the Core, turning it off for 30 seconds, then starting the Blade etc... I have never gotten the setup message where you approve the device.
I have tried everything I know to try and am stumped at this point. I have a claim with Razer support and am waiting for an email from them, but I figure maybe you all might have some good input. Thanks!
Check the cable to make sure it's Thunderbolt 3. This message has nothing to do with the installed graphics card. It means Windows does not recognize the connected device as a Thunderbolt connection.
@itsage, I dont know what @soren_nyquist 's situation is, but mine definitely is. I know because my setup was actually running perfectly last night (no issues). For some reason this issue started occurring only when I turned on my laptop this morning. Any other ideas?
@tymysh0e32, Check your BIOS and see whether you can change Thunderbolt Security settings. By default it should be set to [User Authorization], if possible change it to [No Security] and boot the computer with the eGPU connected.
@itsage, I couldn't seem to find that option in my BIOS, just "Thunderbolt Device Boot Support" as shown in this picture:
I tried enabling this option and rebooting with the eGPU connected but it didn't seem to do anything.
@tymysh0e32, Nope! I actually returned the one I had and bought a Razer Core X Chroma this time, and I'm still having an issue, but a different issue now. Now in device manager its givin gme a driver error with my pcie upstream switch port and pci-pci bridge. New issues no new solutions.
