dual GPU problems/setup

[Komposer]

hi, I´ve insert a second GPU to my 980ti, a 1070.
All works fine, incl. other GPU renderer.
But now the IPR crashes everytime, when I start IPR in CUDA mode.
I´v absolute no idea, if there is something to setup for vray, when working with 2 cards!?
Please help, thanks

ok, a look into the manual makes often sense
The env variable wasn´t set correct and with one click in the gpu-setup tool from chaos, it was fine!

...but vray still chrashes in CUDA!
With this messages...

help please...

Can you share driver version, V-Ray version and the log from the V-Ray console and Maya ?

Thanks,

maya 2015/2017 the same prob
vray 3.4006 official and 3.5701 the same prob
win10
nvidia driver 378.66
vray and maya log files - no idea where to find them

In 3.40.06, when you start RT GPU a separate console process named vray.exe is spawned. It is basically a console with the log in it.
It might be a good starting point.

However, if you prefer we can skip all that and arrange a TeamViewer session with the support. It might be easier just to log in and check what is wrong.

hi Blago, thats a great idea.
How can we organize the TV session?

hi Blago, did you take a look onto my vray.exe output window screenshot?
Is there any intersting information to see?
Seems to be better, we figure it out in this way, should be faster than TV session - nothing happend!
Thanks

I took a look, but it is hard to say what is going on from the window. We should try a team vieiwer (guessing could waste some time).

Blado, since over 48 hours I wait for help.
And nothing happens. Thats hard.
What can I do, to get help from you?
The two cards itself are perfect working. As example is Redshift rendering with both and has no problems!

Sorry for the delay. I guess you mailed the support and you still have no answer back ?

It takes few days to get an answer back. Mark your tickets which are emergency just so they know and they can react quicker.
I will make sure to handle this tomorrow (or asap).
Are you located somewhere in Europe or the time difference is bigger ?

In the meantime, may you try going to %appdata%/NVIDIA and deleting the "ComputeCache" folder just to make sure the driver is not messed up.
Also, which driver are you using ? May you try installing 376.XX ?

Best,
Blago.

I´m located in germany. I think the timeshift sould be 1h!?

"In the meantime, may you try going to %appdata%/NVIDIA and deleting the "ComputeCache" folder just to make sure the driver is not messed up."
I tried to find the stuff, but didn´t.
I gone to user/"me"/appdata - no nvidia folder...
go forward into local folder, then into nvidia folder - no computecache folder...
pehaps you can "spell" me the location - for non computer freakes!?

I´ve installed newest gforce driver 378.66
