Hello everybody,

Yesterday I bought a Razer core X (v1), and installed inside a GeForce GTX 1080TI GAMING OC 11G connect via display port to me screen.
I connected the the Razer core X via Thunderbolt 3 to my Acer Predator G9-591, which is compatible with. I'm using Windows 10 64bits.

But currently the Thunderbolt 3 port doesn't detect the Display.
I checked on google the possible cause and I listed them below:
1: Software Thunderbolt is not up to date
2: Firmware Thunderbolt is not up to date
3: Bios is not up to date

Let's start with the Bios, I currently have BIOS Version/Date: Acer V1.11, 16-Oct-17, I check on the google and found the page for the drivers here (https://www.acer.com/ac/en/US/content/support-product/6370?b=1) but I don't see any new bios ? Maybe someone of you know if this is the last one available for my Laptop ?

For the Software Thunderbolt I tested to install various version as far I know some version are not compatible with eGUP, I installed version 15.x.x.x from support page, version 16.x.x.x and last version 17.x.x.x but none of them have resolved my issue.

So I tried to update Firmware ThunderBolt, for that I downloaded the version on Support page but also some newest version from Intel Site, but every one of these give me the error
"Error: 0x20B SDK_NO_CONTROLLERS - No active Thunderbolt(TM) controller found in the system or Thunderbolt(TM) software"
Here Again I checked if someone on the web get the same error as I, I founded some post and tested different scenarios (Changing version for the software, then for the firmware, then plug/unplung the thunderbolt cable). But at the end nothing as worked for me.

I'm pretty sure that I have to resolve first the issue with the firmware but also with Bios if is an update available somewhere. I don't have any other device for the Thunderbolt 3 port so I cannot exclude a port issue. But first things first.

If anyone has a tip or experience with this, I will be happy to try your solution.
If you see missing information or details feel free to ask me.

Regards,
Marco

    Marconain j0nxx1 (this thread its already more than one year old) thunderbolt for egpus might work or not its always a hit and miss because the port itself might not provide enough juice for the thunderbolt device you are using as i said its not a 100% guaranteed  technology to work with all devices

    This is what on the service manual for your model and we are talking about a laptop which its already from 2015/16 so its already very old comparing to the newer models as as i said the technology evolved in the earlier years regarding the bios update the latest bios its from last year Date:
