    Hi there, I've been noticing flickering or a 'grey line' appearing when I play games on my XFX HD5770 1GB card. I tried to change the voltage from 0.950 to 1.2 via ATITrayTools and it seems to have decreased the effect. So now I want to change that in the BIOS.

    I loaded my BIOS via RBE(using Winflash) and somewhere I read we have to change voltage through the "GPU Registers" but, for me it is greyed out:

    I also want to change my core and memory to a single value to disable PowerPlay "850/1200".

    So how do I do it?
    I tried changing all the clocks above to 850/1200 and voltage to 1.2 and flashed, but after restart, the display driver kept crashing so I reverted back.

    Hi

    Looks like you card may need reseating or you have driver issues; have you tested your card in another PC if it still has the grey line you should RMA the card if it is still under warranty.

    Not sure this is the best way forward,

    Strange 1.2Vm will reduce the cards life, Keep a careful eye on your VRM temps use GPUz
    .................................................................

    VGA Bios is locked - You could try MSI Afterburner and make a profile that will load on window boot
    ..................................................................

    Power Play

    open CCC

    go to Performance/AMD OverDrive

    next

    go to Presets/add Preset -Fill in Name e.g: Default vid OC /Location remove all ticks & then Save

    NEXT

    Goto Control Panel\ folder options/view - select Show hidden files and folders

    NEXT

    open Computer/ explore C:\Users\*Your user profile*\AppData\Local\ATI\ACE\Profiles/you should see your newly created Default vid OC.xml

    NEXT

    Highlite - Default vid OC.xml - press right hand mouse button - select edit

    you will see - Feature name="CoreClockTarget"
    Example-
    <Property name="Want_0" value="15700" />
    <Property name="Want_1" value="55000" />
    <Property name="Want_2" value="85000" />

    raise the Want_0 value from 15700 to 85000
    this will adjust your core clock once you are in the windows enviroment and allows you to continue using AMD's ULps settings. NOTE: this will increase heat to the core VRM's & MEM in 2D desktop mode make sure you have good cooling; and will reduce the life of your vga card

    open CCC go to presets and select Default vid OC; this will apply the new settings

    Note: if you reinstall drivers at any point you will have to set option up again

    nb: only ever flash bios as a last resort

    *Please fill in your system spec's in UserCP if you get a chance the next time you log in

    atb (all the best)

    Hey there, thanks for the instructions I've tried those before some months ago, unfortunately, it seems the flicker line doesn't wanna disappear, what's strange is, if I take a video, there are no such lines, so I'm thinking it might be a Monitor issue now.
