Ok I'll return it, I contacted gigabyte technical support so I should have a response by tomorrow. Do they do refunds or is it returns only?
Usually manufactures replace the faulty parts, if they have them in stock, if not they may offer you another version of the same product, or refund you. By opening the RMA p´rocess you willl have to describe the problem, so if there is a solution they will likely tell how to solve it. So just RMA your card.
