I have two 5850s in crossfire. (ASUS EAH5850 DIRECTCU)


I've been monitoring my two 5850s in GPU-Z at near 100% GPU usage.

I've noticed that whilst my main 5850 clocks upto 765Mhz + 1125Mhz, but my secondary 5850 stays downlocked at 157 MHz + 300Mhz.

Both cards need 6pin + 8pin power connection. But the secondary card I'm only running 6pin + 6pin, could this be the reason why it stays downclocked at 157 MHz + 300Mhz?


Edit: Nevermind. I downloaded the latest version of GPU-Z and both cards clock speeds showing up fine. :)
