Same issue here, getting invalid UID error. No response from support either. Hope this issue is resolved by launch, because then what else was the point of the BF4 edition?
I just picked up the EZ edition card, 1100/1600 was effortless at stock voltage, and runs between 65-70 under load with a custom profile. $205 after rebate, sold the game coupon for $55, so $150 for this card was an amazing deal.
