Hi team.
I've got a few questions about setting up my 4850s in crossfire.
On my motherboard, i have 4 pci-e slots, colored blue, black, black, blue. I've read in some locations that for it to be running in dual 16x i need the cards in both blue slots.
I've read in some other places that it's not true.
I've read in some places that I need the crossfire connector cables attached, and i've read that on newer motherboards it isn't necessary.
Anyway, I've tried one card in slot 1 (blue) and 1 card in slot 2 (black) with the connectors on and it seems to only be working in 8x.
I tried them both in the blue slots without the connectors on (because they don't reach that far) and it didn't work at all.
Is there something I need to configure in the BIOS? Do i need the connectors after all? Will i even notice the difference between 8x and 16x?
Is crossfire even worth it?
-Fallout 3 - on the win7 beta drivers i have a loop on the launcher screen, the game will not start. on the 9.1 drivers, it plays well for about 5 minutes then just freezes... it doesn't crash or BSOD, it just stops and won't respond to anything. system restart required.
-GTA 4 -textures missing and flickering lighting
-Far Cry 2 - (yeah, i know...) Great performance on one card, with CF turned on, it gets 8-12FPS
I've tried uninstalling drivers, running a cleaner, and reinstalling (catalyst 9.1, as well as the win 7 beta drivers from ATI)
Is this all due to crossfire not being stable in windows 7? Or do I have something incorrectly set?
Any suggestions or info would be greatly appreciated. Thanks.
