Hey guys,
 
So I'm trying to get a little more juice out of the 980Ti classified and I've reached my comfortable point temperature. My temps are staying at 69c Max while under intensive GPU load, but sometimes I get a driver reset error crashing my games. I've had Heaven 4.0 run for about 4 hours straight with no problems. I've increased power to 115%, and have enabled maximum performance in the control panel. I'm using afterburner and I have added the 1 values to the corresponding fields and EULA in the CFG file. I've also unlocked voltage in afterburner settings. However, I am unable to go beyond 1.212v on the card. Even if I increase it to +50mv, All software reports a max of 1.212v under load. I'm trying to just increase it a little bit to see if this stabilizes my overclock (who knows, maybe push a little further) and I get rid of the driver crash. I've saved my GPU's bios and I'm ready to flash to a custom one if need be to unlock the voltage.

If you think I missed something, please let me know, or if you could guide me towards the right BIOS to get rid of this limit, I would greatly appreciate it! Thanks guys!

Sounds like you're heading in the right direction when it comes to getting more voltage. Flashing a custom vbios will most likely get you more voltage. Using a EVBot to increase voltage on the gpu is another option.

Thank you, Sajin! I've looked into the EVbot but I'm trying not to shed more hard earned money into my PC, haha! Hopefully I can get some help via the BIOS route! Thank you for your suggestions and confirmation, though!  

Oh wow, no love on this after a few days? :(
 

Use the Classy Voltage Tool, found here Classified Voltage Tool

With this, you can increase the voltage without an EVBOT. You will find that Maxwell doesn't scale well with voltage compared to previous generations unless you get the card into subzero temps, but you can definitely try it out with that.

That should not have been a ROM.  That should have been a Zip file.  Try this one: Here  The .rom may have linked because I am on mobile, and picked up the wrong link. I wouldn't use it simply because I am unsure what it decided to pick up for sure and I don't want you having to reflash.
 
Check out this page: Overclockers.net Classified/Kingpin forum  There is a plethora of Classified and KPE enthusiasts in there 

The following values need to be changed inside maxwell bios tweaker to change the voltage...
 

 
So for example if you wanted to run 1.25v you would change it to this...

Wonderful Sajin, so everything else would be loaded automatically from my bios without having to tweak the others settings? Also, the way you increased the voltage to 1.25v would that still allow me to use any number to the left of that value if I chose to, or would it always be locked at 1.25?
 
You guys are awesome! Thank you for the patience walking me through this overclock.

Yes, everything else would be loaded automatically. It will be locked to 1.25v when boosting only.

Go to the first post in the classified kingpin thread, and download the NV flash from there. When you open it, it will say Joe Dirt. NVIDIA blocked cards from accepting unofficial bios' with nvflash. The version on there doesn't not block you.

Thanks all of you! It did flash with the links provided as when I extract the bios with GPUZ, it shows the voltage at 1.225v, which is the modification I made. However, when I run a benchmark, MSI and GPUZ still remain at 1.212v So it seems it is still being locked at 1.212v even after modifying the bios to 1.225v. Any ideas on this?

Thanks guys!

Sounds like the software is reading the incorrect voltage. To get accurate readings the best thing to do would be to buy a probe it cable from evga and use a digital multimeter to read the voltage. Did increasing the voltage help you gain any stability?

Hey Sajin,
 
It's kind of hard to tell. I just played for about 1 hours before I got a driver crash/reset. The benchmark ran for 30 mins without crashing. but it did stop to think (loading circle from cursor) once while on a loading screen, and continued running normally. Do you think reinstalling the drivers will make a difference in what's being shown? Thanks in advance!

No, re-installing the drivers won't help. You could try though if you want.

1.25v should be fine. Glad to hear everything is working out to your liking. 10MHz isn't going to do anything though.

I'd say 1.28 to 1.3v on air as long as your temps are good. Maxwell overclocks best on moderate voltage increases though.

1600 won't work as the card is hardware locked to not go past 1.281mv iirc.

The software reading could be incorrect.
