I have an Asus z390-p motherboard and 3 Zotec 1660 super cards running. Today I got another Zotec1160 card plugged it right into the PCIe-16slot with all the other cards removed and got the message, no log for miner #1. That is as far as it will go then it disconnects from the internet. I played for a few hours but nothing. Plugged the 3 other cards on risers in and it works fine. Tried putting the new card on a known good riser and get the same thing. I did notice if I plugged a HDMI cable in I get no boot screens but plugged into the motherboard Hdmi port It works fine. Maybe a bad card?
the HDMI thing that you are testing depends on the mobo settings, if you have switched to integraded GPU only , you wont get any display when you put the HDMI in the other cards.
have you disconnected the HDD when moving the GPUs, usually this is not a problem of the GPU. one dude said that he fixed this problem when he got new image of HiveOS.
So I’ve got 3 1660 supers and got a regular 1660 off of Amazon today. Had the same problem. Returning for a new one that should be here tomorrow. Hopefully it’s just a dead card like you said and tomorrow it should work no problems.
