Hi.

I'm having a problem with my trifire setup, its three 4870 cards, all of them gets listed in device manager, and i can use each seperately without problems. But when i go into ccc and selects amd crossfirex, i only get the ability to use two gpu's!?

I can select which two i want to use, but not all three at once, any idea what is wrong? i'm running an i7 920 clocked, 6gb ram, corsair HX1050, asus p6tdeluxe, and intel second gen ssd.

Everything works fine except this, i've tried installing drivers over and over.

Oh, also when i enable crossfire i get BSOD, then reboots and it works fine.

Please help me anyone! :)

what is your motherboard? It may not be capable of crossfire or trifire - check the specs on the manufacturers website.
