6950 shader unlock with voltage control

Last night I read over 150+ thread visited over 10 forums to find voltage control for these cards. I was also trying to solve ATI Tool artifact problem which was really bothering me. A few people who own the 6950 and flashed it to 6970 reported artifact on ATI Tool as well.

After flashing the card to 6970 bios (Asus, Sapphire, XFX, MSI, etc..) all my games run smooth. Benchmark and stress test without a problem except for ATI Tool. I keep getting artifact in ATI Tool with every 6970 bios flash. So I thought maybe that's all my VisionTek could handle... I was wrong. I've read through Guru3D forum, http://forums.guru3d.com/showthread.php?t=335318, and one of the member had a solution. He created 6950 mod to unlock the shader from the original bios without the overclock and the extra voltage. I was contemplated on using it because I wanted the extra voltage to overclock higher. After several hours of reading I decided to give it a try. ATI tool no longer show artifact but I can't reach 840+ on the core due to CCC limitations I came across another thread at 4AM! and got my MSI Afterburner to voltage tweak my 6950 with a few easy adjustment. So now I have an unlock 6950 with voltage control running 6970 spec without no artifacts at lower voltage! It was a win win situation!

MSIAfterburnervoltunlock.exe This version of AB will allow over 1.3v.

After unlocking the shader go to MSI Afterburner directory and look for MSIAfterburner.cfg.

UnlockVoltageControl= 1 (default 0)
UnlockVoltageMonitoring= 1 (default 0)

Then go to MSI After burner setting and check unlock voltage control and unlock voltage monitoring.

There you go... now you have a 6950 unlock shader with your original bios + voltage control and no CCC limitation on overclock.

I increase the voltage by a little bit to show yall that it work.

Ahh I just got back from the Casino guys lost $500 lol...

@ Danja yea you run the batch from window 7. Use Atiwinflash and flash it into the modded bios.bin. From there you edit the AB config and you'll be able to adjust the settings. You use AB to adjust voltage and core clock past 840... AB reported 1200 max on core clock.

@ Yati, I've used ATI tools for years to stress stability so when I see artifact I always think something was wrong, even though all my games run fine. I've search the thread and no one have reported VisionTek 6950 unlocking to a 6970. So after flashing and seeing artifact on ATI tool I was confused on why it did what it did. I flashed my 6950 to so many different 6970 brand and keep getting artifact so I wasn't sure if this was a problem with my card handling the 6970 settings or the bios. After unlocking the shader using the original bios then I concluded it to be a bios problem and not my card. A lot of people didn't have artifact because they're flashing a 6950 sapphire to a 6970 sapphire. Where I was flashing my VisionTek 6950 to Asus, XFX, Sapphire, etc... causing artifact for some unknown reason. After unlocking the 6950 using the original bios and artifact free on ATI Tool and Furmark in which conclude it's a bios problem and not the card itself.

I've tested 940/1450 stable at 1.185v. I'll push some more tomorrow.
