Did you try the Voltage-Hack yet ?

Yeah, don't use multiple OC'ing programs at the same time, they don't usually play well together.
I'm using Afterburner with the Precision X16 skin so I can use K-Boost and the Volt mod at the same time. It works very well.

I thought that could be trouble so I set to default then uninstalled each OC program before using another, and used DDU and reinstalled nvidia drivers after each flash as well. Just cant get PX or AB to change voltage. Did not figure out how to volt hack AB. But I really only wanted it to show the 1.212v, but was stuck at base 1.06. Funny tho... the newest bios for the newest WF3 card must be very different than the OC or GHZ versions. It volts to 1.2 on its own and is far more stable than the other stock BIOSes. Only the skynet bios is as stable, or better due to that rock solid 1.212 I get.

Did you check the "Unlock voltage control" setting in either PX or AB?

Here's the guide I used for overvolting mine: http://forums.overclockers.co.uk/showthread.php?t=18545210

Edit: I cannot change voltage in AB as well without doing the volt hack.

Edit: I cannot change voltage in AB as well without doing the volt hack.

Yes, I changed it in the settings on AB, and ticked it in PX, and in PX the Kboost is disabled. I click it and it flashes on then off immediately. I monitored the voltage with HWmonitor, GPUZ, and GPUshark to check. All reported 1.06 on AB and PX no matter what I did. I have not used the voltage hack so that explains it with AB. A lot of people bash Guru II but I find it simple and easy to use. Not nearly as in depth as AB, but does well. Fan curves suck but... I have a feeling that many OC programs borrow from MSI, but thats just a guess.

If you are so inclined, for fun, try using the bios from the last 780 TI gigabyte made. Ill attach it if you like. I really think many of the problems reported with the first to iterations of the Windforce 780 ti were based in very bad BIOS, cause all 3 cards are the same with different BIOS I think. That 3rd card is only rated at 876 base and 928 Boost, but it boosts itself all the way up to about 1150ish, and volts itself up to 1.20 on its own STOCK. Its far more solid right out of the factory than the GHZ and OC bios. Those 2 cards have lots of complaints about instability, bad overclock, and poor memory modules which may or may not be due to terrible thermal paste application (im reading). The WF3 edition that I have seemed to address these things. If I can get Skynet to mod my bios instead of using the OC version modded bios I think I can push it even more, and would likely be the best modded bios for all 3 models. He goes way further into modding than just tweaking with KeplarTweaker. But he only modded the OC card bios.

My card :

http://www.gigabyte.com/products/product-page.aspx?pid=4912#ov

It seems my card has very good headroom so I did well in the GPU lottery. At 1.212v (that i get from Skynets bios) allows a solid overclock of 1300 core and 7800 memory. Valley tested and stable, but I am right on the edge. Stock Bios gets me about 1270 and 7600, at 1.20v, BUT - I hate the voltage bouncing around on the stock bios so thats why I want to see if Sky can help me out and work his magic on this bios which is clearly different than the OC factory Bios he used. Lock my voltage, get rid of boost, 150% TDP and whatever other magic he can work would be fun to test! Ill attach my stock bios if you or anyone feel like playing with it. vga_bios_n78tw33dfc1.zip 211k .zip file

I'll give that bios a try, maybe I can get 1300MHz stable without kboost.

Edit: I tried it and it's slightly better than the OC bios except the power limit is too low. Bumped it up to 150% and I can do 1245MHz @ 1.212V without K-Boost.

Somehow my cards overlocking is messed up, i am using and i was using skyn3t's Asus Ti DCUII OC bios, even desciption says base clock 1045MHz, it is 1020MHz on this bios?
I think it started yesterday when i decided to update the version of Gpu Tweak to newest, 2.7.9.0. worked ok earlier.
Well the newest version didn't work at all, crashed on Win 10.
So before i was able to set 1200MHz to gpu tweak and and it accepted it right away (saw that when pressed apply, the chart went to 1200MHz for a while, that's how i knew that it was working) and i believe that i didn't even need to set any voltages and power target, just left them default on Gpu Tweak.
So now for some reason boost is not disabled, GPU-Z shows that the clocks are 1200MHz but in stress is just ~ 1097 - 1100MHz.
I've tried different GPU Tweak versions and flashed bios to original ASUS bios and back to Skyn3t's.
Hope you understood anything that i was writing...
Or can i disable boost on my own with Kepler bios tweaker or do you know how to force the boost clock to 1200Mhz in kepler bios tweaker?
Or is there a newer custom bios for this card?
Anyone have a clue where's the problem?

Sweet! I just took that stock BIOS and opened it side by side with Skynets BIOS based on the OC card and changed the values in the exact same way he did, eliminating boost and setting the power tables and all that. However, I cannot edit the boost table in the same way he did, so I just put the slider to the same spot and saved it. The only difference is I put the base clock to 1006 Mhz and clocked up from there. I did get rid of the voltage fluctuation and boost from the stock ROM, and also got it to lock to 1.212v for a stable overclock. Im going to back it off a bit at 1280 core, and 7600 memory for solid stability and game at that level. And with that BIOS, and a fresh install of the drivers and Guru II, Guru started holding the values and applying them at boot. So, I am good to go!

Cant even get this one off the website any more. This also answers the question of which stock BIOS skynet used. It is this one, the GHZ version. I see it in the boost tables. They are different from the other 2.

I can wholeheartedly confirm what DR4G00N is saying. I have been busting my head for 2 weeks with my 780Ti.

The story is I was away for business for almost a year..

When I came back home and builded my new Rig and installed my old 780Ti in it, the latest available drivers were 355.98.

Mind that I upgraded my W8.1 to W10(fresh install), so I didn't even remember what drivers I had.

So after the fresh install and drivers install, setup and everything inbetween, after the OC testing of the CPU, Ram etc I tried gaming on my 780Ti@1250Mhz which was my gaming clocks. I could play also @1270 usually before. But it was a no go! Artifacts! @1250Mhz. I was like what the hell?

I thought maybe its the X99 platform or something. I run it again my default/stock bios again and it was the same. I thought again maybe its a GPU degradation because of sitting in a box for almost a whole year or something.

And NOW I found out it was all because of a fricking DRIVER? I couldn't even run Valley@1240-1245Mhz without artifacts. Far Cry 4 wouldn't run above 1210-1220Mhz without artifacts.

So I found DR4G00N's post about the drivers and installed 353.49Hotfix driver! LOOK AND BEHOLD! All went back to normal! Valley runs@1270-1280Mhz and FC4@1250Mhz without a SINGLE artifact.

So you mean to tell me all this was because of driver? Yes sir, it was indeed. doh.gif

Older drivers seem to allow higher clocks.

True indeed! Lesson learned.

How hard is it to pop the acx cooler off one of these bad boys? im not really having temp issues, but part of me wants to do a repaste for good measure.

Is there a guide of sorts anywhere?
