    I've found something wich Hp dv7 owner gonna like!
    After some test's and try, i discovery the our ati hd4650 can be a beast!
    everybory who try, know this GPU is quite limited, is a DDR3 with 667 memory and dont go too far with overclock(max i found is 645/730 with no artefacts), but what i found?
    I discovered one VGA bios from ACER of this GPU its compatible with our motherboard! so? i extracted the FD bios file this Acer vga bios with a tool calle'd Phoenix mod tool and change from original hp7 bios file (*.FD file)

    Result? Now i have mine gpu up to 800mhz (really ddr3) STABLE!!!!!
    the temps its not too higher.
    mine 3dmark06 up from ~6000 to 7300+++++
    and temps dont go too far after 1 night (6hours) running my gpu temps never pass from 79ºc :| lol
    i think that info is a big achievment for ati mobility hd4650, we can give'em new life!

    there is some photos:
    acctual temperatures idle w/out cool pad
