Problems adding additional GPU - bkoffler - 07-07-2016
I have been working with Hashcat for a while now running with 2x290 on an intel DP69BGB3 motherboard. I recently purchased two additional cards which i would like to add to this rig but i can't seem to get them working. Additionally, i have a 1600 watt power supply for this rig in anticipation of running the 4 cards from it - so power isn't an issue.
The first two cards are connected directly into the 16x slots on the motherboard while the second two will be connected using 1X risers. I know that the computer is recognizing that the three cards are there as you can see from the output below:

All three cards can be seen by the comp, but when i try to run Hashcat to benchmark the program just hangs..
Any thoughts on what the problem could be? I would really appreciate any help you could provide me with.

I would suspect your risers are to blame. Also be sure to regenerate xorg.conf with amdconfig.
