4870 crossfire will not link

[uzen]

Hi, i just recently bought a 2nd radeon 4870 hd 1gb diamond for crossfire. I installed the 2nd card and it says the first card is enabled but the 2nd says disabled adapter instead of linked.... i have tried different drivers e.i. 9.12 8. something. 10.5 10.7 and same thing. I have tried different bridges. i have tried reversing the cards and same thing. I know both cards work for sure so the problem isnt there. My mobo drivers are up to date. Same goes for my mobo bios. And crossfire is enabled in ccc.

My rig is amd phenom 9600, msi k9a2 cf mobo. 4 gigs 800mhz dd2. cp-850 antec psu(850 crossfire/sli supported). so it shouldnt be a power issue.

I have looked in device manager it shows the card just like ccc, and hwmontior. In the device manager it doesnt show the card having any errors so im not sure what to do. i have post on desktopreview.com. but that led me here.

The only thing i can think of being the problem which i dont know how to fix is 1 of the gpus bios diver date is 2009/02/11 and the other is 2008/10/16. not sure if that would be causing it to be disabled.

Please help thanks a lot any input.

Also the screen looks shaky. when both cards are in.

what if you flipped the slots the cards are in, so the current 2nd card is a 'master'
