HD 5770 and 5750 crossfire

Last response: in Graphics & Displays

Just got these two cards all set up in my machine and now im having some issues with getting them to work in-game. I mainly play SWTOR and Battlefield 3, but neither of these games are really pushing my second card to the limits. I am using multiple hardware monitors (CCC, MSI Afterburner, and GPU-z) to see the temps and core usage. Card 1 is at 100% and Card 2 usually sits at 0 but might jump up to 14% every minute or so. Im still getting poor performance on max graphics on both games. From what I have read, both games should utilize crossfire, with the latest drivers and profiles. I can't seem to fix this issue.

Any ideas?

I just switched the two cards (5750 now on top) and the 5770 is showing 0%. Since im running at 4x on one card does that explain why whatever card on the second slot isnt even ramping up in any of my games?

5750 is top card with stock clocks
5770 on bottom (obviously) clocked down to 5750 speeds
Changed some setting in bios that said something like 16x/4x

Booted up and went from AVG. 30fps to AVG 65fps.

Sounds like a deal to me

Correct. BUT, I just switched them back and clocked the 5750 UP to the 5770, making the benchmark crash. So no im tweaking the clocks to get the best performance. I figured that I better have the better card as the main one so that when I play a game that isn't CF supported that im getting the best performance.
