    I haven't done it in a long time. Unpack driver pack in a known folder.

    Enter display driver folder and locate the nvdl file. The name changes a bit through the version but it is something like this.

    Enter your search for the 980m or better yet, search for the string 13D70550. 13D7 is the non gsync 980m and 0550 is dell ID (if I am correct).

    Replace the 13D7 in that line with the correct your GPU has. Find it from GPUz.

    Ex. Replace all the lines you find with 13D70550 with xxxx0550 and only those. (possible 3 or 4 lines is a de the document).

    Lastly, near the end of the file, you will also replace the string to get the correct name for the device properties.

    It is a line that says something like

    Xxxxxxxxxx = '980m'

    Save the file and run setup.

    To get it installed, you have to be in the disabled singed driver mode, if you have windows 8/8.1/10

    I managed to do it (just) and I noticed most guides fail to mention two rather important things, and was the reason I couldn't do it the first time.
    All the guide failed to mention the following, only http://voltground.com had this information which I needed as I am running windows 7.
    • NTamd64.6.0 (Vista)
    • NTamd64.6.1 (Windows 7)
    • NTamd64.6.2 (Windows 8)
    • NTamd64.6.3 (Windows 8.1)
    • NTamd64.10.0 (Windows 10)
    Also another bit of information missing from many guides was which file you should be editing in the first place. Again only http://null-bin.blogspot.co.uk/2015/08/how-to-modify-nvidia-notebook-driver.html
    has the info I needed

    Acer & Gateway = nvaci.inf
    Asus = nvami.inf
    Apple = nvaoi.inf
    Compal = nvcti.inf
    Clevo (Sager & other re-brands) = nvcvi.inf
    Dell & Alienware = nvdmi.inf
    Fujitsu = nvfmi.inf
    HP = nvbli.inf
    HP = nvhmi.inf
    LG = nvloi.inf
    Lenovo = nvlti.inf
    MSI = nvmii.inf
    NEC = nvqni.inf Siemens = nvfui.inf
    Sony = nvszci.inf
    Toshiba Qosmio = nvtdi.inf
    Toshiba = nvtsi.inf

    With both guides filling in the missing information, together I an now I am running 388.43 without problems (for now)

    My problem since I edited the first time, was not knowing which OS was which. Also the file was easy to locate, because the builder string is the same in each line. Hope the newer drivers are better than the older ones!

    So guys, for upgrade my Alienware m18x R2, from Crossfire 7970m to SLi 980m, I just need:
    the 2 cards 980m NO GSYNC,
    the 2 "L" bracket for cover the memory fo the down part
    SLi cable
    Thermal pads, thermal paste
    Bios unlock (with prema?)

    and not need modded drivers anymore!

    OK, I think I am ready to forget about the 1xxx series for now, and go with a SLI, I just hope for some years the games still support the SLI.

    Since, I think a crossfire of 2x 7970m is same as a single 980m, so upgrade with a single one have no sense... thats why I go for the SLI, and i think I can gain the 50% of better performance, it is right??

    Also guys, I have my OS and games in my 512gb ssd msata connected in a sata 3 port via adapter.
    I like to adding another HDD, so I think to move the SSD msata, in the msata slot, that i think is SATA 2
    Do you think I loose performance in game if i do this??

    Bios mod as in the Unlocked Bios. You should be able to find it on the forums here if not we can always link you to it. I don't think Sata in the msata slot is Sata 2 pretty sure it's 3... Someone here can confirm. I have 980M SLI and it's a tank in games even today, definitely a good upgrade.

    I think SSD in games really depends on the game.... A game like GTA V would be different than say a game like CSGO or Dota...

    SSDs don't have a massive impact in games
