My setup was 1 in blue slot 1 in black slot (last slot was empty, black one again). You mean not all Interconnects are the same? But their appearance are just the same to me...for the brands...I don't know which brand for the cable...I just buy it from other people who bought ATI cards associated with this cable and they don't use it that's all
I've tried 8.6, 8.7, 8.8 and none of them show up CFX option in CCC...sigh

Something is really werid as it should be working ... i don't know why they would be not. and 8.5, 8.6, 8.7 and 8.8 drivers all work for these cards.

I mean't brands as did you buy Nvidia SLI ones and not ATI crossfire ones .. and yes no matter what brand of ATI they are .... they are the same.

EDIT:

It could be 1 interconect is not working properly or not fully connected.

Or

your PSU is not up to POWER to power both cards fully.

I am just guessing and only stating.
