6950 shader unlock with voltage control

post #1 of 89
Thread Starter 
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 frown.gif 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!

6950 Mod - Shader unlock http://forums.techpowerup.com/showpost.php?p=2137760&postcount=381

MSIAfterburnervoltunlock.exe This version of AB will allow over 1.3v.
http://www.xtremesystems.org/forums/attachment.php?attachmentid=110036&d=1291470526

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.

I'd like to try it but I'm a bit confused; do I just run that batch file straight from Windows 7?

I flashed my card to 6970 - the ASUS bios - but I would have expected unlocking the MSI afterburner's voltage settings to still work.

It seems not. I set both options to 1 in the .cfg file, and selected the two checkboxes in the settings menu but my core voltage remains locked.

I don't think I have the latest version though... Gimme a min and I'll try again.

EDIT:
Due to some ridiculous steam updates (causing slow download of MSI afterburner 2.0.0) and the fact that it's midnight (causing slow brain), I'm gonna get back to this tomorrow.

Here's a pic of it not working:

Core clock goes to 985 before it breaks down within the first 30 seconds of furmark, making me think I could push this card to 1Ghz with some voltage control.

How did you unlock the core and memory sliders? I flashed the BIOS with the file provided in the post, successfully unlocked the shaders, followed instructions and gained control of the card voltage (thanks!) but the sliders are still maxed at 840/1350. How do you get past that?

In MSIAfterburner.cfg change EnableUnofficialOverclocking to 1

Funny thing. At stock (890/1375) my voltage is 1100

Good info. I have 6950 flashed to 6970bios + OC. I do not have artifact problems.

Anyhow, if your games and stress benches run fine, then why care about ATI tool?

Ahh I just got back from the Casino guys frown.gif 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.

My computer crashed mid-download. I'm uncertain whether it was my graphics card or the new CPU / RAM / FSB OC I was running...

/Off topic
DaRookie - your FSB is stable at 472MHz? Crazy.

EDIT:
Oh wow - didn't realise this. I thought there was something dodgy with a windows experience index score of 6.7 (6.8 after unlock and OC) for my graphics card.
Turns out there's a 10.12a hotfix for 69xx graphics cards:

Well. I have the MSI Afterburner 2.0.0 - still no voltage regulation, in spite of changing the .CFG file frown.gif

I'm waiting for this hotfix to download. According to windows my card is only DX10, so there's something weird going on. It might work after that...

EDIT:
Got the new hotfix, and now WIE says 7.8. Still no voltage regulation though frown.gif

Further edit: 7.9 with my OC. So tbh, I'm fine w/o voltage control from WEI's point of view...
