Reseated the card? Changed the slot? Correct power cables etc?
That looks like a card memory fault or a faulty PSU.
Check your power supply?
If not its broke return it.
Actually some times it can be the BIOS acting up at post ! I've seen it with a GTX 660 before. No artifacts in windows or when gaming nor within the BIOS itself but just during POST.
Some times a BIOS update fixes it.
Does the anomally also occur in windows and when in the BIOS itself ? If so then yes it's defective vram.
Def looks faulty.. It has done this since you first installed it?
