    Here is a link to the new video card I am having an issue with.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16814161245

    For whatever reason I cant seem to control fan speed and clocks with ATT anymore after installing this new video card.
    Anytime I try to adjust the fan speed I get distortion after hitting the apply button then my computer reboots.

    Everything worked great with my 3850, I was able to overclock and control fanspeed just fine with ATT.

    Now my system crashes everytime I try to do the same thing with my 4850.

    I am useing cat 9.8 and ATT 1391.

    What am I doing wrong? Do I haf to do something different with ATT to use it with a 4850 compared to a 3850?
    Any help would be appreciated...

    I use Windows 7 Build 7100 64Bit booted up with unsigned drivers allowed to run.

    Here is a what my ATT config looks like:

    [main]
    ; update information
    ; do not change
    update_server=www.radeon.ru
    fileurl=/downloads/att/update.ini

    ; disable overclocking at all
    ; will be useful on unsupported hardware
    opt_disable_ovr=0

    ; interface settings
    ; d3d/ogl can be hidden only when ATT is not in Control Center mode!
    hide_ogl=0
    hide_d3d=0
    ;
    hide_tweaks=0
    hide_timings=0

    ; Context Help File
    help_file=atitray.hlp

    ; disable checking for supported device in TV/Display module
    opt_disable_dcheck=0
    ; use old I2C access method
    ; for R5xx I recommend to set 0
    opt_old_i2c=0

    ;do not wait for Access_ATI_I2C. Common mutex for all software which access I2C on ATI Video Boards.
    opt_nowait_i2c_mutex=1

    ; disable I2C control functions
    opt_disable_i2c=0


    ; Use old BIOS detection procedure
    opt_oldbios_detection=0

    ; Swap Temperature 0 and 1
    opt_swap_temp=0


    ; Ignore Overdrive suport
    ; and use alternative OverClocking procedure
    ;

    opt_no_overdrive=0


    ; Hide CrossFire
    opt_hide_cf=0

    ; Allow to use Low level overclocking for X1xxx video boards

    ;
    opt_auto_fan_fix=1


    ;

    ;

    opt_force_ddr5=0

    ;
    ; Set to 1 to force ATT to be unloaded before entering suspend mode. ATT will be laucnhed automaticaly after resume
    ;

    opt_force_unload_att=0

    ;
    ; Set to 1 to force ATT to apply clocks even if current clocks and voltage are equal to requested
    ; this option can help to "kill" power play at Windows start up on some HD 4xxx boards
    ; (only for HD 3xxx/4xxx)
    ;
    opt_force_apply_clocks=0

    ;
    ; set to 1 if your board is not yet fully supported
    ; so ATT will be able to read proper clocks
    ;

    opt_use_soft_clk_read=1
