Hello i recently tried upgrading my asus 6950 to 6970 and it all looked promising but it failed! I followed the guide on these forums (link: http://www.techpowerup.com/articles/overclocking/vidcard/159 ), i did everything step by step. However i got the error saying ID mismatch. Well then i followed the instuctions once again and did this:
For the people who need to unlockrom and fail at command line:
- Unpack the Winflash download onto your desktop in a folder called "winflash"
- Save the 6970 BIOS in your Winflash folder and name it unlock.bin
- Click Start Button
- Type "cmd"
- Right click the entry and select "Run as Administrator"
- Black command prompt windows opens
- Type "cd %USERPROFILE%\desktop\winflash"
- Type "atiwinflash -unlockrom 0" <-- the 0 means first adapter, if you have multiple cards, physically uninstall all but the one you want to flash
- Type "atiwinflash -f -p 0 unlock.bin"
- It should complete the flashing process with a message saying something with "verified".
Now once again everything went smoothly and i got to the verified part and all, but after that everything went downhill. I restarted my computer and when windows opened it had a low resolution as if i had been in safe mode or such. However it started finding drivers and it found the drivers and i restarted once again. When the windows now opened again it looked fine, however when i tried checking the shaders number it still showed 1408 instead of 1536. And i got a black screen. So i tried loading the 6970 again on the winflash thinking it would help and it says its already installed. However i keep getting black screens etc. when i open internet or something. Sometimes it doesnt give a black screen tho but after a while it certainly does. So i went to the winflash again and tried loading my backup bios save. It gives me the ID mismatch error once again. What am i supposed to do ? Is there a way i can make the 6970 work ? help please!
