A few of the newest HD7950s are shipping with reference HD7970 PCB designs.
This is a unique situation for the HD7950 because it has improved PCB with higher VRM power output design. These cards have 6+8 pin power connections and 8+8 and are compatible with all reference HD7970 water blocks.
I'm hoping that these cards will all eventually be able to be flashed to full HD7970 performance.
I have done some experimental flashing with my Sapphire HD7950 OC 950mhz edition to HD7970 but haven't had any success yet.
If you have a HD7950 that is using a reference HD7970 PCB please share over clocking abilities and photos.
Here is my card which is totally stable for gaming at 1300/1600 1.22v.
With Swiftech MCW82 7900 gpu block.

How to flash HD7970 BIOS to HD7950.
Thanks to Condrutz85 from Xtremesystems.org for figuring this out. Will not unlock shaders but may have some other performance benefits. I just did this myself and it worked for my card.
