So I have 2 asus 5850 cards EAH5850 with 1gig ddr5 each. I7-930 @ 3.6ghz, CM-v8, corsair tx750w power supply, a couple fans, 1 raptor 10,000 rpm hdd, 3x 2 gig corsair dominator gt 1600 ram/triple channel. I just bought and installed the second graphics card and my performance has actually decreased.
I'm using the 10.8 drivers as the newest drivers are completely useless. I removed the drivers then installed the 10.8. My device manager and ccc both show both cards as installed. However, in ati overdrive my current gpu clock value is stuck at 400 mhz and my second card reads 000 for the gpu core clock and the memory clock.
I have both crossfire bridges installed as recommended by the sticky here in tomshardware.
Prior to installing this I was getting around 100 fps in left 4 dead 2. now i get 40 or less. any and all suggestions would be a great great help. hope i put all the necessary information.
This is my first crossfire setup, so don't be afraid to consider me a total noob.
