    Give a big kiss to Nvidia. They have only delivered crippled drivers in the past. @Mr. Fox can summarize more to you.

    are you implying my GPU fan isn't working correctly? because both cards heat up to pretty much the same temp and both fans are blowing hard

    Anyone been playing GTA V? I've noticed the core stays at 450Mhz even though SVL7's vBios keeps it at 950 standard. If I come out the game and open nVidia Inspector it goes back to 950 lol?

    anyone running a single 980m? my friend wants to upgrade his 675m SLI setup to single 980m but worried about throttling.....?

    this would be for an R2 with windows 8.1

    installed win8.1....nvidia drivers fail to install ....using UEFI and secure boot...

    edit:
    The driver trying to start is not the same as the driver for the POSTed display adapter.

    edit2: im using unlocked slv7 drivers from techinferno on the 780's if that helps

    EDIT3: YOU HAVE TO TEMP/PERMANENTY DISABLE DRIVER SIGNATURE ENFORCEMENT...EVERYTHING WORKS NOW

    as an aside i still cant seem to install the alienware command center

    Hi mate, for future reference you have to do that any time you install any nvidia driver (other than from Dell themselves) because the INF files are altered and there's a signature which you would have come across with the install that isn't verified (but it's how we get it to install on our systems)

    Also, as Mr. Fox has verified anything above 345.20 drivers cause serious throttle issues, I myself witnessed this and it crippled my game performance once 74 Degree's was hit so that's something to take into consideration (I'm using SVL7 vBios as well)
