I have exactly the same issue, but with an FB0 BIOS trting to go to FB1. Same card, same issue.
I tried contacting Gigabyte's support, but they refused to help, as I bought the card in one country, ended up moving elsewhere and then contacted support. They simply told me to go back to the shop where I bout the card...
The card is causing games to crash and I was hoping a BIOS upgrade would solve it, but it seems like I've wasted my money on a card that will never work properly
