AHH NECROMANCY! Lol.
@BYJA. Yeah, me too. Using MSI afterburner to set fan @ custom curve and card crashes. (Stock BIOS never sets fan higher than 76%. Card artifacts before fan goes higher).
Card will crash once it heats up enough for the fan to go to a higher value with the custom setting. Not always right away, but it always does. Tested setting fan @ 100% manually w/MSI AB, same result.
Also using F8 bios. Interesting to note, card ignores BIOS fan settings. Modified BIOS fan curve w/RBE and card acts as if stock. (76% fan MAX)
Perhaps Gigabyte knows the card cannot run the fan any higher, and so disabled bios fan control. My CCC couldn't set it either. MSI Afterburner is the only prog i've tried that can set the fan.
