7970 DCII can't overvolt

[Martini1991]

*An unlocked BIOS for an Asus 7970 DCII specifically*

Aka, someone else with the card or Asus themselves?

That isn't going to make the programs magically update their VRM library.

No but afaik, 7970 specification, whether ref or AIB specific has the potential to go to 1.3vcore.

 

[Martini1991]

The only thing that'd work would be a BIOS that is a constant 1.3v under load, then I could use any 7970 BIOS.

Done a bit of research and this person's in the same boat

Well, TriXX does something different to my card. When left to its own the card reduces gpu voltage in idle mode when it clocks down. However when I set gpu voltage with TriXX, the voltage always remains at its maximum set value.

Suggest disabling what your using to OC and run TRIXX and see how you get on. Note this is the slightly earlier version that allows set volts.

Trixx only takes it to 1.17, which is what it goes to under load anyway.
Plus for some reason it won't actually apply clocks.

No chance of returning the card?

 

[Martini1991]

I could, but it's not worth it.
If I was to return it, it'd only be to go back to my 680.

If it was me, i'd rather have a 680 than a nerfed 7970, heck i'd rather have a 670

Only way I can have my tridef 3D.

RMA card, get a different 7970 if that's the case? I certainly wouldn't want to be restricted to 1.1v on a GPU that can run 1.3v and the high clocks that enables.

With the voltage nerf and your overclock, you're probably getting less performance than a decently overclocked 7870.

 

[Martini1991]

I couldn't live with a stock cooler etc, and I'm not going to pay even more money for what was a downgrade to my GTX680.

 

[dave_beast]

was a downgrade to my GTX680.

Lolz, you can't really compare other 7970's because you bought a lemon 7970.

If I was in the market for a the highest performing card, with considerable overclocking headroom atm it would be this http://www.overclockers.co.uk/showproduct.php?prodid=GX-152-MS&groupid=701&catid=56&subcat=938

Sell the 3 games and recoup some of the outlay.

 

[Martini1991]

You'd have to be touched in the head to buy that.

All of the end users with that card can reach 1300mhz, and no single GPU from Nvidia could even get near the performance.

I see from your sig you have custom water, would it not be more sensible to get a reference 7970 and somehow include it in the water loop with a slightly larger rad etc?

 

[Martini1991]

Are you going to give me the 70 for a waterblock?

Thought you was loaded, buying all those different gpu's so often?

If not, here you go

Far from it.

Is this members the same card as yours?

Yes, if he can overvolt he's got an older stock model though.

Hiya, just a thought which version(s) of asus gpu tweak have you tried?
