The voltage and temperate looks fine for that boost, but your fans are at 0% and 0 RPMs? thinking.gif I looked up that card and it has fans.

When you have your cards in SLI the load is shared across the cards so they are not being fully utilized. I believe that is all the PerfCap is showing in your case. Perhaps the highest clock you can get stable with your setup is ~1400.

I already set the nvidia display driver to non adaptive, max performance....

Thakns

You want to set your cards to adaptive so that they down clock to 135 MHz when on desktop.
The 1 MHZ difference in SLi happens when cards are throttling down. It is most likely a reporting or rounding error so don't think too much about it. Ideally you want to setup a custom fan profile that allows your cards to stay below 80 C.

Thanks I'll set adaptive

My biggest complain and worry was about this 1mhz difference, and yes it happened when throttling

So I do not have to worry about this 1mhz difference? No issues at all?

And to finish, should I let the power limit 100% or 112% for 24/7 usage? Even with overclock for gaming?

Thanks again

Set power limit and thermal limit to max. It doesn't do much except ensures that your cards don't throttle needlessly when in stress. On my classifieds I run them at 141 power and 91 thermal limits 24/7.

Thanks again

So I really should not worry about the 1mhz issue right? Not a sli sync issue or a hardware one right?

Just the temps here are too high, even with the fans at 100% I can easy get more than 80's

my previous 780 ti sli quite often ran at different speeds, nothing to worry about

Thank you for info. I have set on gpu +140 Mhz, anything above that gpu set back itself to 1190 when in 3d application. Max vcore while playing I saw was 1.174 V. I didnt play with vcore yet (have it still on default) as I still waiting for water block to arrive. Then I will try to reach 1500 MHz.
