Got this error on one Sapphire RX 480 Nitro+ 4GB

GPU #1 got incorrect share. If you see this warning often, make sure you did not overclock it too much!

Tried down-clock and stock settings on three different bios-es, tried single and dual mining. Every single ETH share is incorrect. On dual mining all ETH shares are incorrect and the other coin shares are submitted without any problem.

Someone else got this or solved it? Any input is appreciated, thanks.
