Yeah it looks like mine is bench stable at 1267mhz 1.212v but crashes still in Titanfall need to bring it down to 1254mhz it seems frown.gif but it's only that one that crashes while benches and other games it's stable.


I'm trying to use the classified over voltage tool I set it to 1.290v but it's not working when I hit apply? Any ideas how to make the voltage stick?

Seems like I need to throw my hand at OCing my card too.

What I do know is that I can pull the vddc core slider all the way to the left ( -100 ) and the card still remains stable at 1085/1750. GPU-Z says mostly 1.075V and sometimes 1.087V. Don't know how legit it is though.

Nvidia is still very new to me.

1.212 sounds very decent to me as well, but that's from referencing 7970/280Xes.

Is there a reliable way to read the VDDC core? The real one?

I find it hard to believe a 780Ti can run 1160/1850 @ 1.075V...

I could like, grab a wattmeter, but I don't wanna walk all the way downstairs to disconnect it from the mining rig sleepysmileyanim.gif

Edit: It seems the undervolting does work since valley crashes at 1185 @ 1.075V though it normally doesn't.

Scrap that.

For some reason the windforce caps at 1.087V core?

Unless something has changed, nothing will read voltage higher than 1.212v.

But your 1.29v is being set.

Watch your GPU temp just before you click apply on the Classy tool. The temp will jump 2-3c when you hit the apply button because of the extra volts.

Well i just did some gaming and benches temps did not exceed 68c was actually around 66c most of the time.


I have another question though, When you flash the classy which has a dual bios, was i supposed to flash it to the LN2 bios and not the stock one? Because i am noticing my power target only goes to 150.. Did i miss something when i flashed the skyn3t bios?

After flashing the Skynet bios it appears as if the voltage control is broken, I can't OC it anywhere near I could with the stock bios.
Gigabyte 780Ti WF x3.

Really odd though...

What tool you´re using for voltage manipulation ?

Afterburner.
I also use GPU-Z, but it tells me the same as afterburner.

Those 1,21 Volts can be only applied with Evga Precision or Nvidia Inspector mate wink.gif .

Do the following steps one after another and you´ll be good to go :

1. flash the card with whatever bios you wanna use ( stock , sykn3t .... whatever )
2. reboot
3. uninstall every typical tool for overclocking / monitoring of your gpu ( precision & afterburner most of you guys probably have )
4. reboot
5. uninstall Nvidia driver with DDU
6. reboot
7. install prefered Nvidia Driver ( driver doesent realy matter´s at least in terms of voltage delivery )
8. reboot
9. for Overclocking / Volting install one of those : latest EVGA Precision X , Nvidia Inspector 1.9.7.2. <- this is what i use
10. Setup your clocks and voltages and everything should be fine
Now everything realy needs to work at least in terms of voltage delivery

Important :

You need to understand that using MSI Afterburner doesent crank the Voltages on your 780 Ti´s GPU Core up it only adds the voltage to the GPU itself but that doesent help you stabilizing your actuall Overclock .

However if you want to use Afterburner for 64 Bit Monitoring be sure to untik "Hardware Controlling and Monitoring" under Afterburners options so that there is no way Afterburner can manipulate any of your clocks or Voltages and use Nvidia Inspector for Overclocking .

Thanks for the detailed tutorial. Tomorrow I'll try it.
But for realsies, do I really need to reinstall everything?
