I have a problem with my 3 rigs (each of them has 6x sapphire r9 270x). When I turn the rig on, everything works well. But 1, 2 or 4 hours later, one card slows down (from 480 khs to 70-90khs. It is about 10 kh less per 1-2 minutes or less. Look at the picture

It appears in three separated rigs (Mobo: Msi Z77A-G45, 4gb ddr3, 2x corsair cs 650M, powered risers). I tried to disconnect that card, but it is the same (the only difference is that another card slows down). When I plug only one card, nothing changes.
I use SMOS linux 1.3 (+ v4 upgrade)

For 6 cards, error with boot, error with start X
1. You have problem with more then 3,4,5 cards, or you cant boot SMOS. This is solution. Turn off your rig by command halt. After your rig turns off, plugout USB. When you plugout USB, plugin USB on windows machine. Open SMOS label, and goes to the syslinux folder. You will see file named live.cfg, delete it. And DOWNLOAD it file from here (DOWNLOAD name is linked), extract it, and put it in the folder.
Up till now, nothing has helped. In addition - my rigs with 6x r9 280x or r9 290 works perfeclty.
Where is the problem?
Thank you in advance
