AMD Athlon x2 4200
Asus A8R32-MVP deluxe crossfire ready
2g Corsair
ATI Radeon x1950 512 crossfire edition
**new** Diamond x1950 XTX 512 crossfire ready

OK, so before the 2nd card, everything was peachy. After installing the 2nd card, I went into CCC to set it up, enabled crossfire from the bottom tab, ok good to go right? OK, well first thing I noticed is it would not let me run both monitors in crossfire mode, regardless of which port I plugged the 2nd monitor into. Could not find any info on either Diamond, or ATI's websites. Does anyone know if crossfire mode still supports dual monitors? They will both work as long as crossfire isn't enabled. But that isn't the main problem... I ran Oblivion with fraps on, results as follows:

2007-04-19 19:32:03 - oblivion
Frames: 781 - Time: 44884ms - Avg: 17.400 - Min: 10 - Max: 45
**This was with both monitors running, crossfire not enabled**

2007-04-19 19:36:50 - oblivion
Frames: 773 - Time: 44401ms - Avg: 17.410 - Min: 10 - Max: 42
**This was with crossfire enabled, primary monitor only**

2007-04-19 19:39:22 - oblivion
Frames: 806 - Time: 45236ms - Avg: 17.818 - Min: 10 - Max: 44
**This was with only 1 monitor plugged in, crossfire enabled**

OK, so this seems like a problem to me. Not much change at all between the 3. With a whole nother 512mb of video memory, I would expect to see at least a noticeable difference. What else was odd is that I got the highest FPS using both monitors with no Crossfire, which was what I had before the 2nd card. Am I doing something horribly wrong? Or did I not set it up right? Please someone help me!!!

On a side not, the first crossfire edition card is in the primary pci-e slot and does not have the dual dvi inputs. It has the one dvi, and the funky looking port that the splitter goes into. I tried plugging the other end of the split cable into both slots in the second card with no change. Help

hmmm,

Did you check to see if you need to enable crossfire in the bios? some crossfire ready motherboards need to be enabled from bios. Also, are you using the crossfire internal bridges, or the old style double ended dvi external cord?

No settings in the BIOS other tahn the order of the pci-e slots. It is the external double cord, also Catalyst says that crossfire is enabled, there is just no visual improvements
