It's 10MHz so not something I'd have "doubts" about.

Perfectly fine. My cards run at different speeds when in sli too. Welcome to the club. 
 
 

Do you have 1080 SLi as well? Did you realized that did not happened with 900 series?
 
Tks

Perhaps it did not happen with your 900 series cards, but it does happen on many of them.  My 900s in SLI this is VERY common, they are almost never the same.  It has to do with how boost clock functions, and how much each individual chip like voltage.  With 10 series temp will play a bigger role in how far cards boost, so different temps will effect boost as well.  I have seen it happen on pretty much every card I have owned since my 680 4gb cards.
 
I would not worry about it if they were my cards.

Thanks for the explanation, it`s just weird see 2 number not equal when using sli, but its ok :)
 
The diference is 13mhz to be exact

I think i found the solution
If i bumped +50 the % core at Afterburner the problem is solved and both cards stay with the same core, is it normal? Any problem to bump +50? Tks

Guys how are you?
I`m having an issue here with my 1080 SLI
Sometimes, almost always when i launch a game one of the cards do not enter in 3d mode i think, the voltage stay in idle mode and the boost do not happen, i have to alt tab and change some value at Afeterburner to see the card voltage change enad the boost happen
This both images are while in gaming, you can see that one card boost the other one not, sli is active, voltage do not increase as well


What can cause this? Anyone with the same issue with 1080 SLi?
Thanks

Not familiar with afterburner, last time I actively used it was on Fermi cards, but that sounds like a 2D/3D mode is not switching properly.  Does afterburner have dedicated 2D/3D mode functions?

I really don`t know as well, found nothing at settings

^^ Agreed
Prefer Maximum Performance mode is most likely the culprit.  If AB still causes the problem after setting Maximum Performance mode in NCP then i recommend disabling and/or uninstalling AB and trying PXOC and see if that has the same problem.  If it does not then there is a software hiccup, if it does, there is something else, possibly something in the driver that is not terribly happy at the moment.

Thanks so much guys !!!
 
I have just 2 more questions:
 
What enermy method do you recommend to use instead maximum oerformance?
 
And why my cards do not goes to 2d mode when i launch windows or quit the games? This happened with my old 980TI SLI as well, i always have the clocks at full speed, my monitor is a ROG PG278Q
 
Thanks

Here are the top causes of why a GPU would run at full clocks at idle...

#1 You're running multiple monitors. Fix: Enable mutil display power saver using nvidia inspector.
#2 Your machine has a virus. Fix: Scan computer using malwarebytes.
#3 One or more programs running in the background are using your GPU. Fix: Perform a clean boot of windows.
#4 Power management mode inside the nvidia control panel is set to prefer maximum performance. Fix: Set power management mode to adaptive then reboot your computer.
#5 Running a resolution of 2560x1440 @ 144Hz. Fix: Change refresh rate to 120Hz.
#6 K-Boost is enabled inside Precision X. Fix: Disable K-Boost.
#7 Shadowplay is enabled inside geforce experience. Fix: Disable shadowplay inside geforce experience OR completely uninstall geforce experience from your machine (highly recommended)

 
Changing to adaptive and reboooting worked here, both cards are someting like 300mhz in desktop now
 
Should i let adaptive mode so ? What this new mode does? The Bet energy one or better energy one? My software is in portuguese so i don`t know the real translation

Leave it set to adaptive under the global tab. Change power management mode to prefer maximum performance under each game profile.

Not in front of my computer right now, but I believe it is labeled as Optimal Performance.

What`s the diference from this new one to the adaptive and max performance?

What optimal power does...

Reduces power consumption when the computer is idle and nothing is changing on the screen, the driver will not make the gpu render a new frame, the driver will use the already rendered frame from the framestore and output directly to monitor to save power. Adaptive allows the gpu to get a new frame when needed.

So adaptive is still the better option right?
