IF the BIOS switch flip didn't unlock your shaders, then I can almost guarantee you trying to UNLOCK using a FLASH of another BIOS will FAIL also, most likely your cards GPU chip was one of the unlucky Laser Cut ones ... sorry ... but yeah you can still OC the card and get near stock hd-6970 levels of performance.
Note: Also there's been an issue with some of the DIRT3 cards using left over 6990 Antilles GPU chips in them, you can check your CPU-z if it says Antilles instead of Cayman ... then for 100% sure these GPU's are Laser cut and the shader unlock is disabled.
