post #1 of 24
Thread Starter 
i have the 6950 powercolor with the 2 fans and since it has the bios switch i thought i would go for it and try unlocking the shaders now the card wont boot with the switch in position 1, position 2 works fine but i cannot flash the original bios back. i switched back to position 1 in windows flashed the bios back reboot but my pc wont boot
am i stuck with this card only working in position 2 ???

Strange, With wich program do you flash your GPU ?? It's your original bios (back up bios from your card) you want to flash back to, right ?

Boot w/ #2, then flip switch to #1, flash original bios back on, back to square 1.

Btw, did you buy a PCS++? Those are recalled if so.

I did the same, It's easy fix

Boot into windows with the switch set to position 2.

When in windows move the switch to position 1 ( it wont hurt the card )

Then flash back

Haha, You're not the only one my friend. I Have two visiontek 6950's and the flash ended up causing problems on one of mine. Permanent artifacting at stock voltages and core/memory. Anyway decided to just go the safer route with the other card and use the modded 6950 bios (stock voltages but shaders unlocked). Im not sure but I believe that the different mem timings/voltages for 6970 caused my problem but who knows. Getting another one . After examining the cost I might have as well bought a 6990 and left it stock, or minimal overclocking. I'm sorry I cant help myself, Overclocking is just an addiction and so much fun.

I had the same problem. It was easily resolved. I have a feeling you are just missing a few crucial steps.

1) Slow down. Your posting suggests little order to this process.
2) Move all your bios files to a backup folder.
3) Boot windows on #2 switch, open GPU-Z. "Click save bios." (Upper right graphic icon.)

4) WHILE THE COMPUTER IS ON, put card switch to #1.

5) *** KEY STEP *** MAKE SURE YOU RENAME THE 6950 BIOS FILE TO THE CORRECT BIOS FILE WINFLASH IS USING.

OR

5) USE CMD PROMPT: Navigate to atiwinflash directory. Type atiwinflash -f -p 0 bios.bin

Change name to whatever the 6950 bios file saved as. Make sure you copied the bios file to the winflash directory.

Reboot.
