They disabled the cores supposedly because those sections were defective. But this is the amount of ram, and I doubt half of it is defective. The only other possibility is that the memory controller is defective, but then why is it still 256-bit bus? They just deactivated the ram to increase the value of the card, which is evil as hell.
I would definitely get a 4GB version and hack in the 8GB, given that someone figures out how.
