No, if you damage the card you can't. It's in the VRAM that the 6970 has it set to a different voltage, so after a week you get artefacts and you can't revert back. It's permanently damaged.

Thats why Im not using the 6970 bios, I still have the 6950 bios but unlocked with the extra shaders, so Im not upping the vrams voltage unless i choose to do the OC

So the the instructions on TechPowerUp are wrong? I have to download a BIOS and flash it.

What BIOS is this? Link?

Scroll down to the instructions. It says "download the HD 6970 BIOS"

Unlocking Radeon HD 6950 2GB

Here is the site I used and it links to TechpowerUp so its another source of info for everyone.

Here is a pic showing my shaders and when its not OCed

So that one just unlocks the shaders and nothing else? What do you get with it?

I actually downloaded it but hadn't did the update yet.

Thanks

What i have found out is when doing the 6970 bios I couldnt OC the card, but with just unlocking the shaders I can OC the card and keep it stable and cool.

Did you have to increase the Power slider to +20, and did you have to increase the fan speed???

Those are my two main issues as I'd like to keep cool & quiet.

Not worrying about a power supply issue as my PS is more then capable.

Thanks.

Im lucky that I bought an MSI card they use a program call Afterburner and with it i can setup different profiles with using the slider. When i Up the MHz on the chip and ram, I have the fan set to be 10% more then the heat. so if the card is at 30C the fan is at 40% as it gets hotter the fan spins up so when at the max which i have seen with my card of 49C my fan sits at 59-60%

PS the afterburner software is based on RivaTuner you might want to look into that software too.

So you where able to increase the RAM voltage with Afterburner?

DarkXeno · 22 May 2011

As you can see from my screen shot AfterBurner only lets me change the MHz clock on them not the voltage, this might be the a safety setting im not sure.
