Hello and welcome to the forums
Did you remove the drivers of your 4870 before installing 4870X2 ?
Also open CCC>3D>AI, and make sure "Disable catalyst AI" is unchecked.
Hello, and thank you for answering so quickly! Yes I've removed the drivers. I hade Vista 32 bit before and now I've Windows 7 64 bit. So everything is fresh installed and the AI is enabled. I tried to set it to advance in oder to solved the problem but it did't helped
+1^ Catalyst AI disables/enables CrossFire,so when you disable it,one GPU will work.
In some games disabling catalyst AI improves the FPS,because the game doesn't scale well with Crossfire.
I have a 5970 and for some old games like PES 2010 or COD4,when i disable Catalyst AI,i get better performance, but in newer games i can play fine with AI enabled.
So what can I do to use both of my GPU cores in game? I've seen in other graphic charts where they got much higher fps then me whit everything at max settings whit highest resolution on UT3 and in Crysis on 1080p whit highsettings, I only use 1680*1050. How can it be?
Almost, except Crysis. I want to know why both GPUs are not in use in other games except Crysis. I played Blur a couple of hours ago and I was forced to disable the AI in CCC in oder to get bettre fps. I mean all those games supports muliti graphics cards why can't I use them?
And why does Heaven Benchmark 2.1 says: GPU model: ATI Radeon HD 4870 x2 8,753,5,0 CrossFireX 1024 Mb? It has 2gb of Vram! ( AI is enabled) divers: 10.7
And score 1931 (whit settings 1680x1050 full sreen shaders and texters are high, filter: trilinear . AF 4x. Occlusion enabled. Refraction: enabled and volumetric: enabled and rest disabled) is it ok for my system or should it be more?
Well it seems UT3 doesn't like your second card very much but like i said,the same thing happened to me in some games(and many other users i checked in the forums)
When you want to download the VGA driver,always make sure that you download the "CrossFire profiles" too
