how do you know of crossfire is working? just got a 4870x2, I am sure its working but a visual would be nice :)
 
that shows crossfire enabled.. was hoping to see some sort of visual in games. shrug.. no biggie.
 
as much as i HATE Crysis, hit ~ and see how many GPUS its using, when you first start the game it should show you


mine shows 4
 
You could open CCC and look at the GPU utilization ingame... oh wait you need two screens for that.
 
I alt tab in game to check my clocks/temp and I noticed while playing crysis my idle clocks of 507/500 don't increase to 750/900 like they should. While in c&c3 the idle clocks do increase from 507/500 to 750/900. Does anyone know how to fix this?
 
Get a demo/game that works well with CF (meaning not Crysis, try COD4, or if you want a demo to download, try the Call of Juarez or Devil May Cry 4 demo). Go into CCC, disable CF. Test your FPS by either using FRAPS or one of the demos mentioned. Go back into CCC and enable CF. Test again, compare stats.

how do I disable crossfire? And I know gpu's are working even in crysis because I can see the gpu activity rising fast on both gpu's it's just that gpu 1 doesn't increase it clocks. gpu 2 is always at 750/900 and doesn't idle down acording to ccc. I'm new to ati cards and ccc so I don't really get all of it, and the two gpu concept and configuration :confused:
 
There is a checkbox in CCC to enable crossfireX. Untick that box and you are now using 1 gpu.
 
?

he wont get "crossfire" he will get 2 gpus, crossfire is still 2 separate cards in the drivers.
 
I found Devil May Cry 4 to be a excellent crossfire demo. I did some testing with 8x w/ edge detect, 24xCFAA with crossfire disabled and enabled on my 4870 setup. Pretty much 100% scaling. So it was a excellent test for crossfire and if it is working for me.

Was 1920x1200, max everything.
 
I find COD4 to be the best test myself. Pretty close to 100% scaling as well if you raise your max framerate in the cod4 cfg file.
