error 43 could be a riser problem if the card is proven to be working
have you changed the pcie speed (gen1/gen2) in bios?
using the b110 BTC+ im at 8 vegas
I have not touched the Bios. It said it was ready to mine out of the box so I did not adjusting. Should I go in and change the pcie link speed to gen2 like with other boards?
