    Hello,

    I just upgraded my P170-SM with a nVidia 970m and the last official Clevo BIOS can't recognize it... what should I do ?

    When you say it does not recognise it what do you mean?

    Im going to presume you refer to the bios information screen not showing "970M" for the video card.

    This has absolutely no effect on the performance of the card within the system.

    Simply a string in the bios...

    Do you actually have any issues with the card within windows ?

    I have a 980m in my P375SM (originally a 870m) and after installing drivers the machine works great.

    You are true, even if bios don't detect it, W10 can use it :

    1) the 970m is well detected in W10 and a basic nVidia driver is installed by w10

    In this state, optimus is totally wrong (seems inverted), and games can't use it
    Official nVidia drivers setup won't detect the card as compatible and refuse to install

    2) I cooked a custom driver like explained here : https://premamod.wordpress.com/2017/08/15/j95-nvidia-inf/
    ...and installed it in "driver not signed" W10 mod.

    It work great, but I must cook my own driver each time driver try to update and I can't use basic nVidia driver install.

    Is there a simplest way ?
    Can the card be detected rightly by nVidia driver setup ?

    The reason you must mod your drivers is Nvidia drivers come with those lists of hardware IDs which are generated by Vendor laptop IDs and GPU IDs. If it isn't known/approved by Nvidia, that combo will never appear
    in their official driver releases and you must manually inject them each and every time.

    I do so many upgrades for customers, clients, friends and family I'm used to it by this point to get the cards up and running.

    I do wish Nvidia would change their detection and installation process to simply look for the card hardware ID and proceed as such if it isn't able to find a card and laptop pre-approved ID.

    Hello and thank you all for your responses.

    @moral hazard So a modded vbios will change my GPU device ID as a well known laptop/gpu combo, well detected by nVidia driver install ?

    That is my understanding, yes.

    Although personally I haven't tried that as I am happy to update drivers manually, via device manager (using the "Have disk" option and selecting the ini file).

    Okay but you must do it in "AuthorizeNonSignedDriver" mode ?
    So restart before and after driver installation ?

    I'd advise a restart at least with a driver installation anyway :p

    You do only need to do it for each driver installation.

    You would be right, it seems in your case you may need to save your current vbios with GPUz and perform the manual modification via HxD (and Maxwell II BIOS Tweaker for checksum fix).


    I personally wouldn't attempt the modification if you don't have a spare system (or spare old gpu) handy and a SPI programmer on hand for recovery just in case the card is bricked.

    Also remember to keep a full original backup.

    Hello,

    I just tried with the files from this topic... and the card is still not recognize by nVidia driver.

    So I tried to build my own vBios follwing the topic tuto... it still not recognize... so I get back to my original vBios.. at least it worked and I'm now in the initial state.

    ... I really think PremaBIOS is the best solution for me, is there a way to find it "at my own risk" ?

    A little more details :
    Following the steps (creating and updating my vBIOS), have NO effect on the device ID that remain the same.

    And its not supposed to change the device ID at all with a VBIOS change..
    You will always need to mod your drivers.

    You mod the drivers or you download pre-modded files, note that installing every single driver as soon as it comes is not a good idea..
    I usually go months without touching my gpu drivers..

    You are right, I'm updating nVidia driver only in those 2 case :
    • Driver is too old for specific game
    • Windows 10 replace my non-signed driver by basic 3xx version nVidia version (even with Windows Driver Update is disabled)

    Actually I'm follwing the steps described in this page :
    https://premamod.wordpress.com/2017/08/15/j95-nvidia-inf/

    This part :
    "CLEVO OPTIMUS/HYBRID OTHER MODELS 1080 – 1070 – 980M – 970M : NV_DISPI.INF + NVCVI.INF (NV_DISPI.INF_WIN10_OPTIMUS_HYBRID…ZIP)"

    So I'm in V430.39

    It seems okay... but I'm still trying to :
    1. Make it more Plug&Play, working with normal nvidia driver
    2. Find a easiest way to customize the standard nVidia driver
