PROBLEM WITH ONE OF MY SEVEN GPU Tweet

[snake12]

Hi, I need help urgent,
My system was working perfectly and since yesterday I have a problem with my system 1 gtx 580 3 gtx 590 (6gpu) total 7 are gpus, gtx 580 is the principal card 3000 ram, when I start the viewport is as if it blocked the first 30 seconds I can not do anything, then starts working fine but slow and sometimes crashes, if the disable and work only with the 6 590 gpu I can move the viewport very fluid, also when working with 7 580 gps but I put it on low priority.

No problem for sli
The system does not install or change anything

Help please

Thanks

So this is your display card, or is it doing rendering duty too?
Which Octane version do you have?
You have software open GL enabled for display or is it in hardware? Perhaps sli is set somehow - this is not used for Octane and makes for slow/crashes. The card is perhaps not fully seated in the pcie slot? Signs of PSU trouble?? Overheating from accumulated dust??

No use sli and I chek the drives have beta 320 put the 314.22 and nothing. Change the version to 1.1 and nothing and I use the max 2014 change to 2012 and nothing. I use windows 8 32 gb ram. Check bios and nothing. The system Works fine and yesterday appear this problema, and in the render setup dialogue, cuda devices, put low prioty active the gpu 580 Works fine but not the 100% work 90% the viewport run fast

I am not sure what would cause that. Perhaps you could try disabling or reducing the priority of one gpu of a 590 with the 580 running full to see if there is a general problem caused by the combined power draw. Perhaps as I suggest the 580 is overheating a little with dust? as it seems to run ok at a little less speed/work. Is it overclocked at all?
Sorry I can't help much more that that

Edit: you could try swapping the duties around to see if the slow view port is 580 specific too.
