I've just gotten a 4850 and decided to get another to run them in crossfire and my green feet to the land of ATi is showing. Ive spent ages searching but cant find a clear answer to the issues I'm facing. I'm hoping some kind soul can save me from them here.
What I've got;
Gigabyte GA-EP45-DS3R F10 BIOS
http://www.giga-byte.com/Support/Motherboard/Driver_Model.aspx?ProductID=2842
1x HIS 4850 256bit 512mb
1x Palit 4850 256bit 512mb
Catalyst 8.11 (8.12 had issues with crossfire)
Thermaltake 850w
Basically, I'm not sure that its working properly. I couldnt figure out if I use the 2 crossfire ribbons of if my mobo is the sort that doesnt need them. (Im using them currently)
And I get ridiculously low clock speeds for one of my cards
You can see in the overdrive area (which I cant get to work mind you - another thing Im having trouble with) Its adding those two speeds together
I find it pretty hard to believe one of these cards is running those low clock speeds - I mean surely they wouldnt be correct if it is - who would make such a slow card???
Is it that my mobo doesnt use the crossfire ribbons (im too scared to try it without them i dont wanna kill it) or is there a way to enable overdrive so I can set them up properly??
