Windows 8 64 / catalyst 12.6 with 6 7950 even with powered or unpowered risers the two last (blue) pcie 16x don't detects cards only if plugged without risers. Atm only 5 cards running on all 1x filled and the first 16x (two others don't work with risers (1x > 16x)

I'm on z77a GD65 supposed to work WITHOUT shortened pins so idk what i can do now...

is there something to activate on bios ?

thanks in advance

I have a similar problem on z77a GD65 if anyone has some insight.

I am using Windows 8-64bit / catalyst 13.1 with 6 x 7950.  All risers are powered and match the size of the slots (i.e. 16x for 16x).  I have two identical rigs.

Based on the image above (but with a GD65), right to left, I am plugged into 1,2,3,5,6,7.

On both my rigs the 7950 in slot 6 is not recognized.

Thoughts?

Strange, there's a picture of a 6 gpu rig of mine with a GD65 in the thread 1632008 posted. I couldn't get all 6 working in windows with 13.11 drivers, they were detected but code 43'd.

I ended up using linux.
