3060 / 3070 Miner Keeps Restarting or Going offline

I have a rig of 8 cards

4 3070s
4 3060s

Everything was running fine until i switched motherboards. Now the rig keeps resettings.

I tried reinstalling Hive OS and it worked for an hour, but its went off line after an hour. At this point not sure what I should do or what steps to take. I am not applying OC settings, I am using stock settings which should still allow me to use the cards but still getting hiccups.

Try setting up new risers, or try setting up just one card and let it run for a few hours. When you see that everything is ok then add another one. So you add cards until you see which one is causing the problem.

and put OC settings because they are gonna overheat and power off.

Does this line of code help?

Try replacing the riser on gpu2. Or disconnect gpu2 and add other cards as I described in the previous post, one by one.
