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?
