ATi Radeon 4870x2

[amozonesk]

Hi guys, I'm experiencing a little problem - my card is not working like it is supposed to. It never switches to high performance profile (even when activity is 100%, the GPU clock stays on 507/500 MHz) and in CCC it shows that both cards are working only in PCI-E x1 mode..

any sugestions ?

my system :
Win7 x64
MB: Intel P5K Pro
RAM : 4GB Kingston DDR2 @ 800 MHz
CPU : Intel Q9400 @ 2.66GHz
PSU : 1010W Fortron

It could potentially be a driver issue. Maybe install the drivers from the website.
