    Hey gang,

    Since ive already been asked multiple times by various forum members, I thought I might as well just make a thread for this :)

    Background-story: As many of you know, the AMD 7970M doesnt run out of the box in Clevo HM series laptops, since the GPU has an in-built IGP check in its vBIOS. Consequently, the screen stays black with the stock vBIOS, since the Sandy Bridge IGP units are disabled in HM laptops. As a work-around, its possible to blind-flash a modded vBIOS onto the card, thus circumventing the stock IGP-check and making the 7970M fully functional in an HM machine :)

    I have posted this guide before in 1-2 other threads, so bear with me if Im just copy/pasting here :p

    Disclaimer: People, you should know the drill by now, Im not taking ANY responsibility for bricking ur card, world hunger, nuclear fallout or any related incidents! DO THIS AT YOUR OWN RISK!

    ATTENTION! There are several different revisions of the 7970M out there, but only one of them (v1.2) works in the HM series laptops! v1.1 and v1.0 DO NOT WORK, no matter what kind of vbios u flash!

    P170HM users: Please read this post before considering a 7970M upgrade:http://forum.notebookreview.com/sag...bios-clevo-p1xxhm-laptops-10.html#post9892674

    Aight, that being out of the way, heres the deal:

    - download the HP USB Stick Format Tool and use it to prepare a thumb drive of ur choice in windows (choose FAT32 and install DOS files)
    - use a DOS package for the usb stick (in the HP format tool, just point to the directory in which the folder lies)
    - after uve prepared the USB drive, copy ATI Flash 3.95 and the 7970M modded vBIOS onto it
    - now, this is a VERY IMPORTANT STEP: make sure to do a dry run first with ur old graphics card installed!!! for that, u do the following:
    - go into ur system BIOS (press F2 repeatedly right after u switch on ur machine) and put the USB stick on the first priority in the BOOT list, so that ur machine boots from the stick, and not into windows
    - connect ur usb stick and start ur laptop, u will see a typical DOS environment loading until theres just the command line (C:\ )
    - now type the following to check and see if ur keyboard buttons match the input (DO NOT PRESS ENTER AFTER TYPING IT IN, THIS IS JUST A DRY RUN! otherwise u will RISK BRICKING ur old GPU):
    atiflash.exe -p 0 -fs -fp -reboot 7970M.rom
    - after uve checked and made sure that ur keyboard buttons align correctly with the actual input on the screen (for example, the "-" on my keyboard would result in a "/" cuz i have a german layout ), switch off the laptop and install the 7970M in it
    - after installation, switch on the machine and wait for a minimum of two minutes (to make sure DOS has finished loading and the command line is ready for input. its probably overkill, but blind flashing is just something u dont wanna take easily!)
    - input the bios flash command that ive mentioned above and wait till ur machine reboots by itself. until that time do not touch anything!
    - hope for the best that when ur laptop reboots ure able to see the splash screen and windows booting

    and here are the files necessary for this whole shabang:

    HP USB Stick Format Tool
    DOS system files
    Ati-Flash 3.95
    AMD 7970M modded vBIOS for HM laptops

    Update 1:
    Now, some users have rightly pointed out that a .bat file would be far easier in order to do the blind-flashing. I totally agree with that, thus have come up with this lil file:

    7970M Blind-Flash

    Basically, it saves u most of the trouble in typing the commands in blindly. As soon as the DOS environment is loaded, just type in "flash.bat", hit enter and wait for your laptop to reboot automatically.

    Update 2:
    changed the above mentioned .bat file into an autoexec format, its thus eliminates the need of any command-line input completely ;) just put this file onto ur usb drive formatted with dos and atiflash,make sure its got the first boot priority in ur system bios and then let the laptop run its own course until it reboots :)

    autoexec.bat

    Update 3:
    As an additional bonus, I`m providing modified vBIOS versions in order to overvolt the 7970M core to either 1.075v or 1.100v (stock: 1.05v) Based on NBR user experiences so far, 1.075v is very stable and gives up to 30-40 Mhz more overclock capability on the core, whereas 1.100v has been reported to cause instabilities and lower scores when overclocking in some cases.

    All credit for these go to svl7! :)

    OV modded 7970M vBIOS for HM machines

    Update 4:
    This is for all you HM overclockers out there. Aside from OCing with afterburner, there is a lil tweak to enable AMD overdrive in CCC. makes OCing way more comfortable, its possible to force load clocks to 300/150 for a cool silent laptop whenever needed and also solves the 2d flickering issue some ppl were having when OCing with afterburner. first of all, download these two files and manually add them to ur afterburner install directory:

    https://www.box.com/shared/87dxghtm2bhfaonabv5c

    https://www.box.com/shared/90engxolk8x52p4ka5a2

    next, make a shortcut to afterburner.exe and under properties/shortcut/target add the command -xcl (thats a small L at the end). double click on it and ull get a prompt to reboot ur machine. do that and next time ure in windows, start up CCC and ull find AMD overdrive in the performance subsection of ur lefthand side menu :)

    Update 5:

    Seems like this procedure also works well for the Alienware m15x:
    Update 6:

    svl7 over at techinferno has supplied a dell vbios together with his famous vbios patcher. i checked it out and it actually works on clevo 7970M! so in case u have troubles with ur flashed card, u can always resort to flashing that dell vbios and see if that solves ur issue :)

    If you have any questions, just shoot!

    Cheers :)

    Very nice guide JB! + rep

    edit: I think instead of having to type "flash", just name the bat file "autoexec.bat" and that should load up straight away when booting on the USB stick?

    alright,updated with the autoexec.bat :)

    would appreciate it if any users using either of the .bat files could give some feedback. :)

    Thanks once again jb for all ur effort . Turns out , i bricked it and flashing it was never going to save it - maybe sager can salvage it but I don't hold any hopes .

    So feeling foolish I had to spend 320 on another one - though hopefully my naivety will help save some other newbie from making my mistake.

    It's been said time and time again ! But I will repeat never ever ever flash v bios or any bios in windows.


    I had done it countless times and rode my luck but the other day , windows hung in the middle of a flash - and the result was having to buy a new card that could not be saved.

    One good thing though, I have learnt so much about the process and he vbios etc after hours of reading and talking to folk like u, so hopefully that will help me in future.


    Still going to run a slight over clock but with no v bios flashes or volting. 6000 marks 3d 11 will just have to do ;)

    Anyway, now some what of a master in flashing with dos as a result of this, but hopefully a skill I won't be needing to use for quite sometime .

    U live and learn , but seriously thanks for all ur time Jaybee and effort


    Pj

    no need to flash the modded vBIOS on the EM series, since they do have the IGP enabled :)

    oh, but if ure thinking to disable the enduro functionality with that vBIOS, that aint gonna work! :p

    My objective is to save the vbios and modding the default voltage for decrease the temperature.
    you think it's possible?
    Sorry for my english ;)

    i would rather send a pm to svl7,he also modded the existing vbios versions with different voltages. the thing is,i habe no idea how the 7970m would behave in an em series machine with the modded hm vbios. better not risking a brick! just dump ur vbios with gpu-z and give svl7 a shout :)

    edit: if u guys want i could also upload the overvolt HM vbios versions for the 7970m :) all credit goes to svl7 for those!
