Reflashing XFX 6950 2GB back to original BIOS

post #1 of 15
Thread Starter 
After flashing my 6950 with a 6970 BIOS i've been reading about how thats not such a good idea. Now, I haven't had any problems but to be honest, I want to be on the safe side and my card hasn't been overclocking as well as it should have. I want to flash it back to its original BIOS and then simply unlock the shaders as opposed to flashing it with a 6970 BIOS. Stupidly, when I did it, I didn't save the original BIOS. My card is reference and has a BIOS switch (its this card except it doesn't have XFX cut out at the end):



Where would I be able to find the original BIOS and how would I go about reflashing it. Just how I flashed it before? The 6970 BIOS has it at 880/1375 default clocks whereas they should be 800/1250 and the voltage is stuck at 6970 voltage. I want to be able to have my card fresh as it was when I bought it so I can do a bit more tinkering. Thanks

You can check
This BIOS for reference XFX card.
This BIOS for non-reference XFX Card
and This BIOS is the modified one for unlocking extra shaders.

Hope it helps.

Another way to get the original bios, just set the switch to bios2 and use GPU Z to save the bios to a file. If you want to unlock shaders I think RBE will do that now.

So initally the card had the same BIOS twice? That's handy, i'll just do that. Cheers

Stupid question since I've completely forgotten. I have the original BIOS now from BIOS switch 2. If I want to unlock the shaders, how should I go about it. Should I edit the BIOS first or flash the original BIOS first, and then flash an edited one after?

How do I edit and how do I flash the BIOS? As I said, I've completely forgotten

Edit: I can't seem to find an option in RBE to just unlock shaders

Edit2: found it

Edit original bios, flip the switch back to original spot so you don't flash the fail safe default bios, and flash.

I'm trying to flash an edited version of the BIOS to the card and I keep getting an SSID mismatch. So I forced the flash and now I BSOD as soon as I get to windows. Of course this isn't a big deal because I have the other BIOS on the switch, but what am I doing wrong? ATIFLash just doesn't want to flash so obviously RBE isn't creating the file properly. Lame. Any ideas?

Edit: I just flashed the original BIOS (from BIOS2) to slot number 1 and it worked fine, no problem. This means ATIFlash and the original BIOS are fine. It's just the outputted BIOS from RBE isn't working. Am I doing anything wrong?

I figured it out and now its perfect. Thank god for the dual BIOS switch

You can't flash the failsafe, hence the term failsafe.

You can unlock the shaders, overclock to 880/1375 and push up the voltage so its basically the same as a 6970. Then you can OC further
