Much to my surprise, I received a response from ASUS.Apoptosis wrote:If you'd like to remove your HSF and post pictures of your video card front and back I'm sure we will be able to help you out.
With so many versions and revisions we really need to see pictures.
“Dear Valued Customer,
Thank you for contacting ASUS Customer Service.
It's a non-reference card.
Best Regards,

Hopefully this will be a help to others.
I would not flash this card, however with GPU-Z “latest version” it is possible to change the stream processing units (shaders) to 1536 and this cards GPU can be overclocked to 950MHz (or close to it anyway), leaving you with a 6950 equal to or maybe better than a 6970 without flashing.
If I break 950Mhs, which I think I can, I will post again with the info. I suspect the fans will need to be swapped out but we will see.
