Just went through this last night. Picked up a MSI 3060ti from best buy. Put it on the test bench and had intermittent trouble with it freezing in the background and the worker will drop offline in app. Still mining I’m background then eventually it will lose its connection stall and freeze.
I have had problems with that test bench’s Mobo before so since it had mined for a couple minutes I figured it was fine. Moved it to my main rig which had one slot left on the BTC h110 and immediately did the same thing. Literally took hours of work to get anything back online and it directly affected the network connection to all my other rigs and the tv.
Prior to plugging that card in the main rig I ran net-test. All green and pings anywhere between 30-300ms depending on how far away.
Ran it again while troubleshooting with the 3060ti in and it starts failing all over the place. And that problem will start within a couple minutes to affect the other miners on the network.
Pulled it out and moved it over to the test bench again and loaded windows this time. Mines fine in Windows environment swapped back to hive on same test bench and back to knocking out network connection and freezing in background with mouse and clock still active and current. And also if you touch the power button to the board it will hard freeze with that card installed
