A Little Story Behind -
I had overclocked my card to 900/1275 and was going to overvolt to get further. Before that i decided to read some user experiences at newegg. Saw this -

Bios Switch unlocks 6970 shaders.
So thats how the fun began.
How to Unlock -
1. You need to have a Sapphire HD6950 with a dual fan cooler. 1GB or 2GB both have good chance of unlocking.
2. Make sure the card is running at stock 800/1250.
3. Turn off the system, open the cabinet side panel and locate the BIOS Switch on the card. Its near crossfire bridge connector.
4. Flip the switch towards right.
5. Reboot.
6. Open GPU-Z and you shall see this hopefully -
7. Now you can overclock it to 880/1375 (the HD6970 speeds) (Note - Every card is different. Some cards may need overvolting to get to 880/1375. Overclock at your own risk)
What about noise? I have read this card is noisier under load (just like other dual fan cards). Even my single fan's noise is audible at 50% and above in winter when the ceiling fan doesn't spin.
Jas, superb work buddy. You are becoming pro day by day. Now you got a HD 6970 from your HD 6950. So I don't think you need to puch the card much further.
Jas does we the owners of 6950 have chance to do this . i ask this question bcse we all have different company cards only kapilove have and i have the same company card. can we do this or not . and yes nice oced jas & cilius check Ur spell mistake u did it in a hurry i think edit it .

Of course, it won't be just a flip of switch, you have to actually flash the BIOS. Else there are scripts to do it automatically. But beware, this might be risky and there's no guarantee. In any case, always backup the original BIOS.

thanks cilus.

scores in line with 6970 and 6950 scores. i used same settings.
in 3dmark11 i think they have used the score combined of all 6 tests whereas i have used 4 GPU tests only.
in unigine i think they have used default settings.
