Rendering with 2 cards / stranges settings

[toketronic]

Hey Guys - i finally got my Titan and Gtx480 up running and i'm doing a comercial project on them now, and started out having my card render settings like this :

GPU0 : Titan Use pri: on

GPU1 : GTX 480 Use pri: off

And then i could see that the titan was running 99% and the 480 up to 70%
but it keept chrasing, now i chance it so the titan is of the 480 is on
and i can se the 480 is 99% and the titan around 69%
1 thing it renders 15% faster 2 its stabel, i thought my titan was suposed to run on max and the other card to run my viewport and help out a bit. is there something i misunderstood??

All the best love this engine

okay i said it was stabel to fast the render are going down every time now ??

if You want to run monitor from 480 simply hook the wire into it & rom CUDA devices leave 480 untucked where it says ACTIVE. Only Titan should be left as ACTIVE. Take off all priorities too - this will push the card to max =)

P.S. as for stability, You power supply might be an issue (if it renders fine with Titan Only, then I would take a close look at PSU)

what do you mean with crashing?

Now i took my cabel and put it in the the 480 and it for sure faster now, with crashin i mean it renders some frames and then at a point it chrashes and it not a very big scenen it only a logo and a object in a cloner out in object mode and some efektors spreding it out, but halfway it went down, hoping that the chance of screen to the grafich card did the trick its still running now and faster,ohh noo just went down again,hmmm what can it be, any idea witch settings woould be the best or should i disable the 480 ?

I have platnium 1500 watts power supply so its not that, could it be something with the combi of cards, or the settings ?

Please test your HW. Plugin has not any problem like that.

i'm checking the HW right now but strange enough yesterday i render som big scenes with lot's of objects and it was fine, it seems like its when i use cloners with alot of clones the problem started

[aoktar]

if you can render it with single card, this mean that's not a plugin problem. if you're sure plugin problem, send me your scene

Thanks aoktar , will send it later if i don't find a way i have a deadline tomorrow morning so i really hope so, but now i see something really strange, could the driver for the grafichs cards be mixed up, when i turn of the titan 8 gb of v ram comes and 2 when i turn it on crazy now im re installing them, did not thought this could happen
