Hi, I recently purchased an XFX HD-695X-CNDC Radeon HD 6950 2GB. I was hoping to flash it to enable 6970 shaders but everytime I try I get a subsystem id mismatch error using ATI flash and the sapphire bios. The card doesnt have the bios switch and I've read mixed feedback so far. Does anyone know of clear steps I could take to enable the bios to unlock the shaders? I was also wondering what's the best program to use in order to overclock the card as well. Thanks!
