    Will Microsoft update the Win10 upgrade?

    When I updated the bios my settings went back to stock. Tried it wouth those. Still no joy. The OC has nothing to do with it.

    There's a boatload of BIOS files in the 'VGA BIOS collection' database, which is accessible from the TechPowerUP home page.


    If you are getting unrecognized hardware errors after flashing a modified BIOS, you may have gotten a little overzealous with the editing. There are some areas that you must not change.

    I suggest you read the RBE Tutorial and proceed with care.

    Yes I read turtorial))
    TechPowerUp here I d'nt sea my bios. My car is 4850x2 1 Gb (2x512) there just 4850x2 2 Gb (2x1024) (((

    In RBE I just edit Clock settins to 700|1100 (card work corectly in 730|1200) and change fan settins (100% cooler after 70C) and change overclocking (driver overclocking limit) from 700 to 800, memory from 1200 to 1250

    ЗЫ Sory for my bad english Ну не помню я его не помню...

    ah, editing the overclocking limit directly will most likely NOT work. This area of the BIOS is protected by a digital signature from ATI.

    If you want to modify that you have to 'inject' a signature from another card. This is all covered in the tutorial.

    and i need default master and slave bios for my 4850x2 1gb (2x512) (

    there seems to be three here...


    but I don't know how to differentiate between master and slave bios... don't have any experience flashing x2's

    I wouldn't worry about finding a pre-modded bios, since it is a simple matter to make your own changes. Just always start with a clean copy and do not re-edit the same file over and over.

    From what I've read elsewhere on this forum though, the 4850x2 can be a difficult customer...
