the problem being that the nvidia driver included version being 470.86.
To fix this problem, install this version instead: hiveos-0.6-211-stable@211104.img.xz
This release contains the nvidia driver version 470.82, which works fine with the newest Hive OS version (at the time of writing, being: 0.6-214@220331) and has no issue with the nvtool, and also works with the new VRAM temperature display which is being supported by many miners nowadays.
Also, a minor issue, under the individual worker page, the motherboard info is currently not being displayed properly:
I too have 3060 ti and I contacted rebetch, there motherboard are not compatible with the 510 drivers. they told me to try 470, and I had no luck, I ended up getting another motherboard that supported 510 drivers for the LHR unlock, let me know if anyone has any luck better then mine, cuz I have two of these motherboards
