2x7970 freeze windows and linux too

[hoze]

You can also use the -d 1 and -d 2 to check cards individually and maybe see which of the cards create the problem, or both, who knows...

OK, I will try that now. In meantime I change one of the PSU and now I can run in full speed both GPU,but after 3-5min the system is freeze. Before with old PSU after few second the system freeze,so I think the PSU is the trouble maker

Here is log from both GPU (running stable 3-5min)
