    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 ?
