    I got 25k but had to run my card at 2114-2101MHz to achieve that.

    No you're right, there's something fishy but I just wanted to point out that 25k is probably not achievable on stock clocks, but idk for sure. Though he should get at least 24k.

    I'm starting to think that by the time the UK gets stock of the custom built GTX 1080 cards that the GTX 1080 Ti will have been announced!!!

    Guys how are you

    This is the max i achieved at my 2 EVGA Sc 1080

    [​IMG]

    This makes the boost 2079 on cores

    I realized that changing the voltage at afterburner did nothelped at nothing to bump the core and the memos, is is normal? And the final result of 2079 for an sli is ok?

    Thanks

    Atleast you will get some free games at that time, now nothing :p

    It is normal if you understand what are you changing. Increasing GPU Boost 3.0 voltage doesn't add per-VF point voltage offset. Those who try to increase GPU Boost 3.0 voltage should check that thread:

    That voltage IS the max for that card.

    You cannot force anything with that slider. But you can allow GPU Boost to select higher voltage/frequency points on the curve, so just increasing the overvoltage % alone will not increase stability but may increase performance under conditions when the performance is limited by maximum operating voltage selection.

    Wrong. Once again, you don't force anything with GPU Boost 3.0 overvoltage slider. You just extend the range of available VF points for GPU Boost.

    Default voltage of Pascal cards is around 1000mV (+- dependig on leakage level), it is pointless to expect the driver to allow you overvolting it by 250mV.

    Really good review mate I enjoyed reading and concluded pretty much the same myself, yes, the 1080 is the fastest but the price/performance is horrible in my opinion

    Guys can you help me again with one thing?

    At my 1080 SLI when i start a game both cards have same clock, for example 2079/2079

    After some minutes one card goes to 2063 but the other one stays at 2079, this not happened with my 980TI SLi rig, is it normal? If no what should i so to maintain both cards equal?

    At MSI Afterburner 4.3 beta 4 the cards anre synced

    Thanks

    Both are under 60C the power targetr is the one at msi afterburner, in the options seems that cards are synced

    The best asic (boost) card is on top, before make the sli i tested both alone to see wich one had the best original boost

    It`s weird, if i alt tab at the game and appply the over again it comes to normal
    Some msi afterburner or driver bug maybe?

    Tks

    The way boost clocks work with Nvidia's new GPUs they won't ever stay at the exact same clock(s), even with 1 GPU let alone in SLI. They will fluctuate up or down due to a variety of factors and it's working as intended that way. Don't worry about it my friend. Enjoy some nice 110% maxed out 4K gaming with your new setup. :)

    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

    Thanks

    Maybe the bottom card needed some extra juice to reach thetop one oc and the 50+ fixed it?

    I've noticed the same behavior and it freaked me out a little as well, but it doesn't seem to affect stability or game performance. GPUZ and Afterburner both report the miss match in clock speeds. Waiting for the next driver and the new bridges to appear to see if it fixes it.

    I found the solution

    Bump a little the voltage, something about +50 is enough

    Seems that one card needs a little more juice to achieve the best card sli core, since i bumped a little the voltage both cards are working with same cores always

    Hope that fixes yours :)
