Please can someone advise me here.
I am using 2 x cards for Octane Rendering, a GTX 760 and a new GTX 780 Ti running it via DAZ but the problems persist in standalone as well. I don't play games, so I have no other software to test it with apart from 3Dmark11, where my machine was a bit off, but basically within the score of most others submitted with my spec (see below).
I think my shiny new GTX 780 Ti, which I ebayed like a nutter for is duff. I'm hoping it's my lack of knowledge somehow.
It will not get anywhere near the stock temperature of 82-83 degrees. It should be capable of maxing out in the low 90s.
The highest it got to was 78.
It will generally crash as soon as it goes above 73.
The longest I've been able to use the card is 50 minutes at 70.
Clearly I can't go on like this. I need stability and running at lower temps means sacrificing performance (about 10 percent imho).
My other card a GTX 760 runs in the same machine for hours. I've run it for 24 hours no problem for example.
I've been using OC GURU II to limit the temperature and set a custom fan setting (makes a lot of noise at 90%!), but this only slows down the inevitable.
EDIT the motherboard is an ASUS P8Z77-V LX, which is PCI-e 3.0 ready and in independent tests 95% compatible with the GTX 780 Ti (this is a good score btw).
Memory is Corsair, PSU is corsair AX860 - easily enough juice.
As I say - it runs the GTX 760 no probs.

No the rest of the system is fine. What happens is the GTX 780 ti has some kind of crash, and then stops running, cooling the chip down due to inactivity. DAZ crashes at this point (just hangs), Octane Standalone carries on with just the other card.
I'm not sure if waiting ages allows it to start up again in standalone, but given I'm no where near even stock speeds, this is pretty hopeless. Unless I'm missing some setting somewhere?
I've had my 708 TI render under full load for over 24 hours straight and had zero problems. You might want to contact the manufacturer and see if you can RMA it because it might be a faulty card.

Thanks. I go straight to the manufacturer do I? I've never had a g/card go down before. Must have been lucky - owned PCs since 1994!kavorka wrote:I've had my 708 TI render under full load for over 24 hours straight and had zero problems.
