I have: set OC to 0, reseated cards, reinstalled Claymore, run bluescreen troubleshooter in Win 10, reinstalled all NVidia drivers 22.21.13.8569.
I have not: rolled back driver, bypassed Afterburner (the only way I know to OC).
Thanks, Roy
Are you using Risers? might be the culprit, I suggest to install GPU's without riser first, if your mboard supports 2 PCIEx16 then install 2 GPU first within the PCIEx16 slots and resume mining, observe, add GPU's one at a time to isolate your problems.
