Scotty I just tried the Classy tool. I had AB running at the same time with the voltage on that unlocked and on +62 (max it goes). Also had the classy voltage tool open and unticked auto. Put the slider to 1.25V and ran a bench but the max voltage it shows on AB is still 1.212V.

Am I doing something wrong?

No, AB doesn't show the actual voltage.

I will add something to the OP about the Classy voltage tool at the weekend, so any and all info would be appreciated

I love a bit of plagiarism

Do you have a copy of the tool?

Thanks Scotty. Yes Greg it appears that it works in terms of setting a higher voltage (got the card to 1300MHz core at 1.25V; max on stock volts was 1256MHz). It just doesn't display the actual voltage on AB. I believe it is the same with Precision X but haven't tried the latter. Slightly annoying but will get used to it.

If your still on air, if you use 1.35v(max) keep an eye on the temps as it gets hot quick - set fan to max

Oh - have fun

Do you guys reckon I should try skynet?

Evga allow flashing so - I'd go for it, if your happy to flash your card

Cheers Scotty. Yes still on air in this AMD FX system and as long as I can hover in the low 1300s on the core, I'm happy. Did notice temps go near 80C at 1.3V/130% power limit.

Yer, I will have a look at it tomorrow. I have it linked in the OP.

Mine hit high 70's, but my card was in a 350D so wasn't the best airflow.

I can send to you it if you need it.

Err! I've not see 80C yet.

Cheers for the guide, managed to flash my 780ti classified LN2 bios with the one from skynet

I have a few small problems however -

I cannot get afterburner to unlock the voltage at all, ri3/4 does not work and it comes back invalid?

when using the EVGA classified tool it will not let me adjust the voltage, it stays at 0.9v at idle and only jumps to 1.1v at 1230mhz in GPU-Z (assuming this is giving correct readings)

Any ideas?

Gregster · 10 Jan 2014 at 21:49

You have to use the Classy voltage tool and Afterburner/GPU-Z gives false readings sadly.

Hey greg, I gave this a go on my reference EVGA 780Ti but was unable to change my voltage from 1.075v. The slider would go up and down but nothing would change.
Any ideas mate?

When you say the slider would go up and down, what is it showing if you move it to the right?

thefogo · 24 Jan 2014 at 21:32

It goes up to +100.
EDIT: sorry not +100, it just has the voltage in mV. It doesn't change no matter what I set it to. Even at 1.3v it keeps at 1.062v in GPU-Z.

thefogo · 24 Jan 2014 at 22:39

Nevermind, I guess it's bugged for GPU-Z. The voltage shows fine in afterburner.
I didn't realise it set the volts as constant though

You say a ref 780ti , how are you getting 1.3v ? , max with skynets bios is 1.212v, you can bios mod and soft mod all you like but unless you've found a magic cure you wont get 1.3v

The 1.3v afterburner hack is what this thread is about

It doesnt work

Hello everyone, after a long jorney spending time into bios and reading to get moar voltage for us. I finally come to say the voltmod for all 780 Ti is not possible by Bios, EVGA PX or MSI AB.

This time Nvidia has locked down us users to 1.2 by hardware no drivers or bios but with a little mod i could get it to 1.212v not much but it does the job also increasing the power limit too and lock down boost to gain about +13 Mhz to +26 Mhz moar.

This is due to too much RMA going on. a lot people are abusing they GPU and many want to do something that never did and don't read how to and in the end mess thing's up. so unfortunately the journey to get it unlocked by bios or drivers has not much success.

The only way to by pass the voltage on a reference 780 Ti is my hardmod a 100 ohm resistor. You do need a stead hand's and skills on soldering. it is only two points nothing more but two points that can cost you a GPU. so if you don't know and want it done ask someone that has done it before for you.

Remember doing any soldering point's you will loose all the warranty on your GPU. so this is no turn back if you fry it. you be on your own. it will going to give about 1.5v. as I read and informed about the reference 780 Ti the PWB is so weak. it may fry quickly than any 780 reference. believe me or not this is the info I granted from the PRO'S.

780 Ti reference Volt mod: Spoiler! (Click to show)
I need to talk with OCN stuff because I will be doing it as a service if any of you want it done. so I still need permission.

I'm still looking into the Asus DC II if I can get the voltage unlocked. only time will tell us.

So sorry it toke a bit longer with this locked down result but this is all Nvidia not me. I wish I could do it without the hard mod for everyone.

best
