Crossfire Radeon 7850

post #1 of 14
Thread Starter 
Hello, i recently got a second ASUS radeon hd7850.
when i plug it it, i notice a slight increase in performance, my question is, how do i get more out of my crossfire setup? am i doing something wrong? all i did was plug it in, plug the bridge in and start the pc, the second gpu is recognized and thats all i did, what else can i do to improve preformance?
i run crysis on highest settings and get about 45-50 fps, with 30 while theres a mess.

how about ULPS? is it disabled. i used Trixx to disable it. the other thing is you can synchronize the cards using Trixx as well.

hope those help. run 3DMark11 before and after you set those (if they are not set). btw, you are talking about Crysis 1 right?

C3 is much more demanding than other games like BF3. with the 7950/7970 xfire and i7 SB @4.5, i was only averaging 59 and min fps dipped into the high 30s. that was using Very High and 4MSAA in 1080.

btw, i never synchronized my cards. i also never used Radeonpro, which according to some helps in performance.

OK, tested 3dmark benchmark scores:
before overclocking (800mhz both cards) and ulps enabled: 9744 score.
after overclocking (1200mhz both cards) and ulps disabled: 10977 score.
thanks for the help guys, anything else i can try?

That seems low. I've run a 2700k at 4.5 with two 7850's stock 860 core. 3d mark 11 P was 12k+
