    Now you dont need to use AMD GPU TOOL to set the core speeds
    keeping ATIPLAY enabled and idle speeds enabled :)

    just flash this bios onto your 5870 cards make sure there based on the reference cards if you flash any other 5870 other than asus ect.

    this bios was uploaded by RBE developer and fixes the issues we all have with 5870s trying to get them past 900core 1300 memory with the MSI overclocking tool :)

    have fun cause i will.

    Extremly good find :)

    Flashed both cards with the 1200/1400 bios and your tool fully works now
    still some bugs with sync mode as sometimes when you change a setting the other card doesnt unless you manuely select them ect ect

    but as for everything else

    GPU clocks ect and Voltages aswell as Ati power play all fully working :D

    Thats the thing with blue smoke. When it gets out, it never gets in again.

    A couple of questions.

    1/ The bios you linked to is 123kb wheras the original bios of my Sapphire 5870 is 128kb...what gives? and theyre both .bin files?...thought they were supposed to be .rom files?

    2/ what are the paramaters for flashing?

    Im pritty sure the bios i flashed is 128k as i just looked :)
    all you have to do is rename the .bin to .rom so that atiflash can read it.

    the flashing info is straight forward.

    atiflash -i
    Command to use if your under crossfire to see what your device id`s are being 1 and 0

    atiflash -p -f * bios.rom

    * = your device id 0 or 1

    just remember to back up your original bios with GPUZ.

    Thanks for that, just re downloaded the Asus bios and it's 128kb, for some reason the other time I downloaded it it came up as varying sizes eg 123kb :3eyes:
