The fan in my NUC 6i7KYK recently went out, and after warranty with Intel, I was able to purchase the 8i7HVK. I have done a clean Windows 10 install, and am using the latest version of drivers for both the Intel graphics and the AMD RX Vega 64 (per Intel the latest working of Adrenalin, 20.2.2).
With the 6i7KYK, I was able to use the Asus XG Station Pro with the AMD 5700 XT card, and it worked flawlessly. I have installed the XG Station drivers, and have the latest Thunderbolt 3 drivers and command center working.
When I turn on the XG Station and open the Adrenalin software, it shows both the RX Vega 64 and 5700 XT. However, when I go to open GPU Tweak II, it says "Load vender.dll Fail. Please install VGA driver.".
This issue *only* occurs when the XG Station is powered on. If it's turned off (only the Intel graphics and RX Vega graphics are "on"), GPU Tweak II will load without issue, showing the RX Vega graphics. And with the 6i7KYK, this issue never occurred.
I need to load GPU Tweak II because that's how you control the cooling fans in the XG Station Pro. Since this worked fine with the 6i7KYK, it seems to be related to some kind of interference with the RX Vega graphics.
I have even tried installing GPU Tweak II first, then doing the AMD drivers to see if that helps. That process was as follows:
However, with the Adrenalin 20.7.1 drivers, as I said, the second monitor no longer works, night light no longer works, and the native resolution is terrible. I then repeated the process above, except installed Adrenalin 20.2.2, and was able to solve those issues, except GPU Tweak II will not load for the 5700 XT (or show it in the drop down).
tl;dr what I have concluded is this:
Any suggestions or feedback as to how to get this solve would be much appreciated. Thanks!
