    Hi guys, i want to flash the bios of sapphire 7970 vapor-x 6gb with the bios of the 7970 toxic 6gb to unlock the voltage and have better over lock possibility.
    How I need to do? Where I find the modified bios for my video card?
    Thank You ;)

    Hi

    Welcome to TPU

    First
    make a backup of the original vbios image [for when things go wrong]
    download and run GPU-Z here
    Example
    Extract vga bios.jpg
    Select: vbios chip icon
    Select: save to file [vbios name.rom]
    [*keep a copy in a safe place*]

    Windows
    select a copy of the vbios image
    press right mouse button; from popup menu Select: send to compressed (zipped) folder
    TPU Fourm Post
    select: "upload a file" attach a copy of the vbios.zip

    Edit
    Note: use afterburner, sapphire Trixx or other third party software to OC to attain stable core and memory clocks that can be used 24/7 before flashing a vga card

    Note: edit a copy of the original vbios image [is better to do this]

    nb: go here fill in full system specs brand names and OS

    Hi

    Attach a zipped copy of the vbios image here; [instructions in previous post]

    members of the TPU community need to look at the vbios image first, before giving advice

    Hi

    Thanks for attaching the vbios image :toast:

    Note: with regard to the attached vbios image; the voltage regulators are fully supported by VBE7.
    Example
    CHL822x.jpg
    "The following voltage regulators are fully supported: CHL822x, CHL8214, UP1637, UP1801, ST6788A, VT1556M"

    Source: here < Read this.

    Make a backup copy of the original vbios image and *use VBE7.0.0.7b.exe to edit desired 3d core, mem clocks and voltage

    Before flashing an edited vbios image
    Note:
    use MSI Afterburner, Sapphire Trixx or other software to OC and test stability in all applications and games

    General rule of thumb
    Factors to be built in to the OC process

    -Fabrication process of the GPU [differs from one to another some OC well and other not so well]
    -[General Rule of Thumb]; to find out the max OC, increase 5~10Mhz on core in stages test at each stage, if the system freezes you have gone to far, lower the OC by 40Mhz and then start the same process with the MEM increase 5~10Mhz once you get artifacts back the OC down by 40Mhz; Use GPU-Z to keep an eye on VRM Temps these can rise quickly when OC's are applied Keep these between 70~80c : 85c Max]
    -Adjust vga card fan speed manualy
    -Be aware that some games do not like OC's and testing with each game as well as benchmarks is nessasary
    -Make sure the drivers are stable; if they are unstable they will crash the OC
    -Check that the motherboard is setup and chipset drivers are up to date [Run CPU and MEM at default speeds while testing vga card OC]

    (Remember to uninstall vga drivers before flashing at a DOS prompt)
