Has anyone had luck unlocking a HD-695X-CDFC card (e.g. make a HD6950 into a HD6970 pipelinewise - the overclocking can be done separately)? I know it's not reference, but it does have 2GB memory and I've seen that other XFX boards have been unlocked not being reference (the primary thought was that non-reference cards will be unlockable was overthrown)
