Intel Thunderbolt 3 Controller Update (on an Intel NUC) + an eGPU
I've been successfully using a Gigabyte AORUS Gaming Box 2080Ti with my Intel NUC (NUC8i7BEH) for over a year now, and apart from an issue arising from BIOS update 0083 for the NUC (which has mostly been resolved by modifying some security-related BIOS settings), this combination has been working well.
Looking at the drivers page for my NUC model, I now see a release of a Thunderbolt 3 Controller Firmware Update (version 0046), dated April 26. There is no detailed changelog for that firmware update, with its description only stating that it provides "Security Enhancements" (it is unclear what these security enhancements precisely are). I don't have an original Thunderbolt Controller Firmware image, so that I am not sure that reverting to the previous version would be possible, in case of an unforeseen issue.
Has anyone with an eGPU applied said Thunderbolt 3 Controller Firmware update 46, and could share their impressions?
One more thing: the release notes document that is downloadable along with the update states that a Thunderbolt device should be attached to the NUC before and while updating. Because I use an eGPU, I am concerned with the possibility that updating the Thunderbolt 3 controller firmware might result in a loss of image signal, during the update (the computer outputs image through the eGPU that is connected via Thunderbolt 3). Seeing that one must have a Thunderbolt 3 connected before and during performing this firmware update (per the Release Notes document) – and that I don't have any Thunderbolt 3 device apart from the eGPU in my possession – I don't know how I should proceed. Does anyone have any suggestions?
Thanks a lot!
@pavelpr, Doesn't the NUC have it's own video output? Use that while doing the firmware update. If you need to connect a Thunderbolt 3 device, connect the eGPU without the GPU installed.
It does, but once the eGPU is connected, video through the iGPU would freeze (remain static) as soon as Windows has finished loading, and subsequently all signal passes through the eGPU.
At any rate, my main concern has to do with not having a downgrade path. For instance, BIOS version 0083 for my NUC model included security fixes that affected Thunderbolt connectivity. Applying said BIOS update impaired eGPU connectivity for me, and it took quite some troubleshooting to identify the issue and to work around it. To top it all, Intel blocked downgrades from version 0083, because it contained security fixes.
Seeing that said Thunderbolt 3 Controller Firmware Update is said to contain "Secuirty Enhancements" – and that I don't have an image of the firmware that's presently installed on my NUC – I try to exercise caution.
