    I have an aorus x5 i just got last week. I started installing games when it was using windows 8, and then ugraded to windows 10/

    All the same games that recognize vram in their settings now say i have 8 gb ram instead of 4 gb.
    Including windows.... I think 3dmark always did that.

    but what has happened. the other x5 owners noticed it too. The game is a dx 11 game so how does it now use the vram from both cards?

    Read the change log. It is the driver. The one I linked only just came out yesterday to address this exact issue you're reporting.

    I think its just a way of displaying the information. And to be honest it seems to be right way because you do have 8 GB vram physically. Its only due to limitation of SLI that it acts as 4GB. I dont think its a glitch. But i cannot confirm this as i dont have windows 10 or sli laptop.
    Just my 2cents. :)

    Well its just windows getting ahead of itself for dx 12 games. But reporting both gpus rams to a dx 11 game.... Should make it overwrite to ram.
    I was wondering if windows 10 has some magic sli ram enabler in it.
    But actually its what prime said all thats changed so far for dx 12( dx 12 is installed in windows 10) is it states all the ram you have.
    The game itself will have to write to the ram. That we havent seen yet.

    Unless its magic. I need something that uses more than 4gb ram to test maybe

    When you run anything in SLI, the same data has to be written to both of you cards vram so that the two cards can process it properly. That is why the the vrams dont simply add up.
    I dont know how directx 12 will function, but i feel that it will not be an alternative for SLI. I know MS said that DX12 can work with dpu+igpu, but i think it will be mostly for post processing works. Major work will be done in main card.
    This is just my opinion though.

    Win 10 has vRAM reporting errors for now, and SLI errors too.

    Dufus also found that it was stealing vRAM from GPUs as well (1/8 or so) with at least 353.62 drivers. I haven't seen any later evidence, but Dufus is MIA for a bit, so I can't get him to check, and I'm not on Win 10 nor will I be for a few months, and even if I was I don't have the cuda program he used to check vRAM allocation.

    In short, anything weird with Windows 10 and vRAM or SLI? It's probably not changed from before, it's just Windows 10 and/or drivers being stupid.
