    Nice. How did you do this? (LLC / OC controls?)
    *Edit* Saw you used "RU". What is this? Is there a link?
    And what is FPT?

    Bios Modding Guide

    All tools in link below:
    https://drive.google.com/open?id=0B_bTuwDv_P1GRm04SlJSTlloV2s

    If you have a 6820HK (GT73vr 6RE) you can skip to step marked * and flash the included bios rom after disabling your bios lock using the guide as is.

    1) Disable secure boot in BIOS (this is found in BIOS/Security/Secure Boot Menu).
    2) Get your bios from the MSI website and extract the BIOS file from archive.
    3) Open the downloaded BIOS using UEFI tool. Click file -> search, search for GUID 899407D7-99FE-43D8-9A21-79EC328CAC21. This will cause a line of text to appear indicating successful search. Double click this line.

    Note: If this specific value ever becomes outdated, simply search for 'BIOS Lock' - in APTIO-V the bios lock will typically be stored in the Setup DXE. It is probably sufficient to simply search for and extract the Setup DXE

    4) A DXE driver should now be selected called Setup. Right click and save this as is.

    5) Use IFR extractor to extract the saved setup.ffs

    6) Open the new file generated called setup.txt
    7) Search for 'BIOS Lock', you will come to the line displaying the address of the bit used to store the BIOS lock variable. eg) 0x5AE

    [​IMG]


    This is specific to the laptop/bios version so it will vary! Note it down.

    * Now format a flash drive using rufus to 'boot efi using MSR'. Extract the contents of the EFI archive in google drive to the formatted usb.
    This should result in E:\EFI\BOOT\bootx64.efi

    Note: It is possible to boot RU without a USB by booting directly to RU EFI. Google this.

    8) Boot the USB drive, this brings you to RU (it'll be tiny if you're on a 4k laptop).
    9) Click return to escape the menu and do 'ALT =' to bring up search.
    10) Search 'setup'. IF this brings you to a page with only two lines of hex this is not the right page, use the PageUp/PageDown keys to get to another page also called 'setup'.
    11) Once on the correct page use CTRL PgDown until you reach your address, eg) 0x5AE for anyone with a 6820HK.
    12) At the address should be 01. Type 00 and write this to the address using CTRL W.

    I had to do this several times and kept cycling pages back and forth to make sure it stuck!

    13) Once the 00 value has stuck at your address, reboot and flash your modified bios with administrator FPT -F biosname.rom -bios

    To actually modify your bios dump it in FPT using -D bios.rom -bios. Then open it in AMIBCP. That program is pretty intuitive and allows you access to ALL THE MENU's. To make all menu's accessible click the advanced tab and change all menu's from default to USER.

    Note: FPT sometimes refuses to play nice, removing .rom from the command, or -bios may resolve this.

    EDIT: I updated the archive with a working Rufus and a pre modded bios for the 6820HK. PEG1 is set to enabled to avoid black screen when switching IGP/DGP. Full voltage controls are enabled (I recommend LLC values of 15 for both AC and DC in core). To avoid throttling raise SA/CORE/RING limits.

    The 75w limit of the PCIE rails can be changed using this bios, the option is found in Advanced/System Agent. It probably doesn't do anything but who knows 0.o

    Overclocking performance menu has many goodies in it

    Set the lock to off by default

    with very limited information of GT75, it's hard to say for sure but yeah chances are that keyboard of GT75 will fit with GT73 but with complete keyboard / mouse panel if connectors / cables will be same.
