Hey I got the same Card as you CDC 951.
 
And I cant pass the 1500 wall. Im getting PWR in PerfCap meaning that I need to push the TDP, so I can OC more lol.
 
Sajin made you a custom bios the 1420X should you recommend to upload that one? or the 980Ti-SC-425-1281mv ?
 
BTW, in running on a full custom loop.
 
Thanks buddy !

This is my PC.
 
Its a Z170 Classified with a i7 6700K. It has 3 EVGA 980ti's SSC and a EVGA 1300 G2 SuperNova.

Use the one I linked in the home page in caps and huge letters 1420x and work your way up from there also open gpu-z and click the top left corner for all your cards and look for something called read asic quality. It is probably one of your cards not being a good overclocker.
 
 Report back on what your Asic is on all 3 cards :) mine is a 64.8 :( so I cannot go past 1420 MHz lol
 
 
The higher your Asic is the better the overclocker it is  Also the newest drivers are very wonky with overclocking so it is not your fault. For now just overclock them a little and not go so hard on it till NVidia Drivers are cleaned up. May I ask what driver you are running? Try 353.62 Google it and let us know how it works out for you

I'm testing one by one, and the one I have installed right now. It has an ASIC of 82.9%.
 
So I upload the 1420X correct ?
 

Before I read your post I uploaded the 980Ti-SC-425-1281mv.rom and know I have TDP @ 121% and 1.274 volt running the GPU.
 
But you say its better the 1420X ? than the one that Sajin said on the first page ?

Yup the one Sajin made 1420x is the best trust me and you need to give us the Asic of all 3 cards you got. You see in your gpuz photo there is a drop down bar that says 980 ti on the bottom left of the program. Click on that and change cards to read each cards asic and upload 3 different photos. Btw 82 is amazing so far

Guys, I'd like to edit the bios of my 980 Ti Hybrid, to achieve the followigìng:
Max safe voltage (I assume first slider to 1.281)
Max power limit and/or TDP (I assume 75W+75W+150W, even if my bios seems higher for 6 pins)
Keep stock boost, and stock at default values of PrecisionX, but maxed when moving the sliders...
Could someone suggest me? Thanks!

You're correct. You can edit your own vbios using maxwell bios tweaker v1.36.

Many thanks! Could you please check if this bios is correct? I Raised volteage to 1,281, TDP and power limit to 300W (just upping sliders). I left the 6 pins and 8 pins as in default bios, they seems to be both higher, but if ECGA set them in this way, they sould be safe...

I think those cards should do just fine, the acx cooler is amazing
