It just happened when rendering with Octane. After about 30 mins. of rendering it just turns off. No warnings, just... boom, you´re off.
After a couple fo minutes it turns on again to normal. Anyone can bring some light about this? I´m really pissed with this, specially in the summer, that´s why I think about overheating.

Hi, Paquito.

My guess it might be PSU, ..but let's see:

Dowload & install GPUZ,
open a GPUZ window per GPU & activate log files to write all sensors of every GPU (should have separate files for every GPU)
Now work like normal & attach these log files after crash =).. - we'll see if crashes are caused by GPUs =)

How do I set it to have a long for each card? I have a 690 and there appears two cards with sli enabled. Should I make something special or just leave it as it is?

You can probably just monitor the temperature of one of the 690's (since they are the same card they will have the same temp). Also, my understanding is that you need to DISABLE SLI.

Sorry, I must disable SLI to work with octane or to make the logs?

Also get MSI afterburner to measure gpu temps. You can also monitor if a card has power spikes bumps that are caused by the psu when rendering.

For Octane disable SLI

Could you expand that a little? Why you should disable SLI for Octane? Should I disable also for gaming? What is the difference?

Otoy recommend disabling SLI for rendering (http://render.otoy.com/faqs.php). A number of users have reported that enabling SLI has caused crashes.

Ok, I see. By now I disabled SLI and will continue working under gpuz monitoring so I can have some info if the problem appears again. Thanks.

cool, let us know!
