Then I install ATI Tray Tools 1.36.1042: http://downloads.guru3d.com/download.php?det=733
This tools wrongly detects my card's clock...
My card have 830 Mhz Core / 960 Mhz Memory Clock...
But detected as 13.5 Mhz/13.5 Mhz ==> Too slow, even for desktop operation
And when I modify my clock settings using this ATI Tray Tools...
I move the slider to 840/970, then click apply buttons, and suddenly a blue screens appears...
It says that exception occured at ati2mtag.sys.......
*********************************************************
Then I uninstall this tools, and want to overclock using ATI Catalyst Overdrive again..
So strange... My ATI Catalyst Overdrive doesn't work anymore...
When I move the slider to any clock (for example 840/970 Mhz), then click apply to change my clock, the slider suddenly come back to default settings (830/960)... NOTHINGS HAPPEN!!!
Seems that I can't change my clock speed anymore...
So I FORMAT my Harddisk and REINSTALL windows...
Then install Display Driver and Catalyst 7.9 (I didn't touch ATI Tray Tools anymore)...
My ATI Catalyst OverDrive STILL DIDN'T WORKS!!! Even after I FORMAT my HARDDISK and REINSTALL WINDOWS!!!
I DIDN'T TOUCH ATI Tray Tools, but WHY???
The Slider settings just move back to default settings when I click apply (nothing happens), I don't understand..
I think my card's BIOS settings has been changed? Or something what?
Please help how to solve this issue, I cannot overclock my cards right now T_T
