Then this might be a heat problem. Try running both cards with an open case and maybe put another fan there.

It's allready a open case . I can touch the card with my hand, and it's not that hot!

It's strange that freeze after 3-5sec. I think the card can't get that high tempeture in 3-5 sec.... These cards with 3 cooler on
each...no way to get overheat in that short time...

...does somebody know what is the symptoms of low PSU maybe ?

Well, if I understood correctly one of your post, your 2 GPUs were on 2 separate PSU so if they run fine alone, then it should not make a difference if they run together (PSU wise). Are they both directly on the motherboard or you are using PCI-E extenders? Make sure that they are well seated in their slots. I can't think of anything else right now. I don't know if it does still make a difference but if you have crossfire, disable it.

Yes, separate PSU and directly on MB,without extenders and without crossfire!

if it's happening on both windows and linux then you know it's not a software or driver issue. if each card works fine individually then you know it's something like your motherboard, bios settings, psu, etc.

I think the PSU is the problem. I will replace it today and post the result...

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)

I test both card separately with -d 1 and -d 2 option and work fine. Here is the log for -d 1:

...just one thing I don't understand. With " -d 2" every time i press S for status I got different util value.Sometimes 43%,sometimes 84%,then again 50% ,tempeture only 31c, but the "Speed.GPU" stay allmost at 157k all the time and the remaining time is shown correctly.
