6950 Bios switch?

[~Divine~Wind~]

Do all of the cards have the bios switch?

I was looking at Xfire 6870 as an upgrade to my 5870 but I think the extra vRAM on the 6950 2Gb models may be beneficial (using eyefinity) and then posibly adding another 6950 later down the line.

Was looking at:

If so any experiences with these cards?

If you mean the BIOS switch to unlock the extra shaders then that's a rarity these days.

There's only 1 HD 6950 available now which seems to have a realistic chance of unlocking: Sapphire ATI Radeon HD 6950 TOXIC.

But there are no guarantees.

The SAPPHIRE TOXIC HD6950 has a BIOS switch that allows you to choose between a standard HD 6950 BIOS with 1408 Shaders, or an HD 6970 BIOS with 1536 Shaders. Many HD 6950's can be flashed to an HD 6970 BIOS, but this one comes with it already done for you. SAPPHIRE has made it extremely easy to possibly get a lot more performance out of this video card. SAPPHIRE does not guarantee that all the extra shaders will work for the card, or that you will receive any performance gain by using it. We did see a noticeable performance increase when switching to the 1536 Shader BIOS however, but your millage may vary. It was with this BIOS switch, and overclocking, we were able to beat an HD 6970 and GTX 580 with this video card.
