Hello,
I hope you can help me to get my rigs up and running. I have 5 rigs with 4 x 7950 each. 3 of them run fine but I have trouble with 2 of them (same hardware and software).
One miner Windows/CGminer just doesn't recognise my 4th card (can't find it in Windows Hardware as well). I already tried a lot: test each card single, test all/different slots, connect then direct to the motherboard/use risers. On another rig I have a setup working perfect by using 3 x 1x-16x risers and 1 x16 straight on the board, this is exactly the same hardware/software.

Card is fine, tested it on other rigs. Of course I also tried to connect 4 cards on this rig but it also doesn't show up:

- I think the PSU is enough 1000w premium brand - other rigs run just fine
- Lower intensity/config
- Rebooting a lot / removing .BIN files
- I'm connecting via Teamviewer, so no output is connected to the cards. However, tried to connect HDMI/VGA adapters to the cards to 'activate' them, no success
- Latest driver/update
Some weird stuff:
If I connect only one card to the motherboard (tested all ports) it works fine, just not with 3 - 4 cards.
Using CGminer 3.5.0 - here is a config file:

Thanks!
