Unlock voltage Gigabyte HD6970 Windforce

[rabiesekorre]

Hello

I recently bought a Gigabyte HD6970 Windforce3x and thought I could do some great overclocking. But I discovered that the voltage was locked and I couldn't change it. Can anyone help me unlocking it with another type of BIOS or something?
GV-R697UD-2GD is the modelnr.
And yeah I've tried unlocking voltage tweak in MSI Afterburner by editing the cfg and so on.

Did you set UnofficialoverclockingEULA = 1

OR

UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it

?

Also you could make a copy of the BIOS and increase the 3D Mode voltage using RBE (Radeon BIOS Editor) if RBE supports your cards BIOS, then you'd need to flash the card with the modified BIOS.

Yep I've done both of them.

Sure but it seems a bit risky flashing the BIOS every now and then. Maybe that's what I have to do.

I'm just throwing it out there, Its dangerous so I'd only recommend doing it if you MUST over-volt and you really know what your doing!.

Sure, but thanks for the help, I didn't know if it was possible changing voltage in the BIOS.
I've flashed the BIOS on several graphics card and I know how it's done

That didn't work out very well, bluescreened at windows boot and I had to reflash it.
Any thoughts?

I have no idea what you changed man?

Maybe you can upload the file to a file hosting website then we can have a look.

Sorry, the only thing I did was setting the voltage to 1.25v at the "boot"clock. Standard bios apart from that.

Did you use the clock tuning wizard to adjust the 3D mode voltage?

MSI afterburner only works with certain cards. Use Sapphire Trixx..it will let you change the vcore voltage. I don't believe any 6970 has the option to change the memory voltage.

Sure, here is the original BIOS:

No not really, I don't have that great memories using automatic overclocksoftware.

Thanks, I will give it a try!

Umm, Sapphire Trixx didn't work. It just looked like this:

The image shows the voltage listed....whats the issue? increase it from 1175 to 1200 and you should be able to hit 940 core and around 1400 on memory

I'm not stupid, it just changes back, I doubt any software will work.

 

[dharmenparikh]

It changes back that means it does work you just need to figure out why it doesn't stick. There are options for Trixx that restore locks on startup and make the program run on startup. However if you open CCC after using Trixx....it may causes issues when you bootup and restore clocks to default. That might be your issue

I think I've tried everything possible with Trixx now and I can't get it to stay..
Anyone who actually knows if it is even possible changing the voltage.

 

[rabiesekorre]

Ok, now I got this clear, Gigabyte locks all these GV-R697UD-2GD voltages.
I'm not even sure if a BIOS change would help..
So at this moment there is nothing I can do sadly enough..

Either way thanks for all your help!
