    Just got sapphire HD4770, flashed to Asus top mod bios.

    Overdrive set to 870/950 low power swaps to 250/950 leaves mem unchanged at high clock, is this the norm? is it a problem with the current hacked drivers? or is it something to do with flashing?

    thanks for all and any help:toast:

    Not sure.

    How do you swap BIOS?

    Could make make a how to thread to do this?

    Also how do you like the Sapphire Hd4770?

    Does that heat sink on the voltage regulators work?

    Great card , excellent value for money.

    got mine to replace an overclocked 3850 783/1043

    Bench on sanctuary doubled frame rates.

    As to flashinf bios, force flashed Sapphire HD4770 to ASUS Top mod bios with atiflash this allows an ATIOverdrive clock increase up to a max of 1000/1200 instaed of the standard 830/850. Also allows use of smart doctor to mod voltage.

    I am no expert on this, and only found this out googling so if you chose to do the research first.
