Also would like to add that Ive been following this closely (since I ordered a HD 6950 before knowing about this little trick)and not everyone has had it work for them. So, it is not a 100% guarantee it will work. So, that leaves me to believe some cards were binned as HD 6950's due to the fact they actually failed testing in some way, while a good majority were perfectly good 6970 chips that were bios crippled to fill the segment.
