Still have the same problems. Performance are so bad when i activate both cards. is my CPU bottlenecking? i have only 6 gig ram installed on my PC too. bcs of some defective i have.
Correction guys, i have the HD6900.
After i activate the crossfire i check my AMD Overdrive:
1st card shows: 450 mhz GPU and 1250 MHz memory
2nd card shows: 0 at both.
will this change when beeing ingame or what?
When i activate crossfire this is making my gfx perform bad compared to only a single gfx card. i have i7 950 CPU and 1000W PSU. what do u think is the problem?
