unlocking shaders in MSI 6950 PE card

post #1 of 6
Thread Starter 
I followed the tutorial (powerpoint) from MSI, used the unlocked bios and even used a user-submitted unlocked bios from techpowerup that was specifically for this card. I tried numerous permutations of the different setups, even tried to do the flash in Winflash but kept getting a 'Rom Programming Fail' message. It only 'succeeds' in DOS but when I reboot and check in GPU-Z I still only have 1408 shaders. I have also tried re-installing my drivers after the flash and the shaders are un-changed. What might be wrong, and what can I do? Thank you for any help.

PE?

Is it supposed to be a guaranteed unlock?

Well, not that I'm aware of. Reviews on Newegg and a few accounts around the web have reported success. MSI even wrote a little guide on how to do it. I guess that's why I thought it should work. The only reason I bought a 6950 was to save money and unlock it. I guess I will need to sell it, though I should have just returned it since it was sold to me as new but was used.

Which card is the PE model?

I just unlocked my MSI 6950 2gb, the other day. I had to follow the additional instructions by booting into CMD as admin and running those atiwinflash switches.

Once that finished, i rebooted and it asked me to reinstall drivers. GPU-Z found the additional shaders.

I am not familiar with you card. I am assuming it has only BIOS switch. If it has two switch, make sure your booting up with the switch you flashed. Also, I have read somewhere there is a version of GPU-Z that does not show shaders correctly. So make sure you have the latest version of GPU-Z.
Can you note down the exact sequence you are following when unlocking via command prompt?

I experienced exactly the same thing. I have MSI 6950 PE (Twinfrozr III OC)
No luck with atiwinflash - it was throwing errors under gui and cli.
It was possible to flash under dos. gpuz still shows 1408 shader count though... If it grab the bios from the card using RBE the switch for 6970shaders is checked. So it seems flash was successful.

Do you think additional shaders are in use and gpuz is just confused? (gpuz 0.5.3)
