I don't have your card but have run into that message in BF4 in the past. That game can be very picky with overclocks. So I would suggest you return the card to defaults if it is not and try again. If that doesn't help I would try running DDU from wagnardsoft_com and reinstall the latest driver.
You might want to verify your game files too.
If that doesn't help contact AMD support and see if they have an answer: https://www.amd.com/en/support/contact-email-form
