Odd...how much did you overclock?
Paste OverdriveNtool.ini or your settings for memclock etc.
nothing extreme
https://ibb.co/gmmC7G as I said 16 others works just fine !
Hate to ask this, but I'm assuming you already did DDU, reinstalled drivers, tried a different PCI slot.
My guess is the card is suspect. Can you isolate this card on another system by itself to see if the issue carries over?
yeah man did everything

on a clean install + updates + ddu + blockhain drivers + alone on the main pcie
