Why RT crashing my driver today and not yersterday ...

[ghiom3d]

Hello,

Today i can't use vray RT GPU.

I had working yersterday and since the release with it fine. i go to sleep, i'm wake up and now everytime i start a GPU render vray.exe windows show me :
Error CL_Out_Of_Ressources (-5) at line 1947 , in file ./src/ocl_tracedevice.cpp !!!
the render is cut in some square where some are nearly black.
My Nvidia drivers crash, the recover .. then crash again and my windows restart ...

My system is clean, i have reinstalled everything in a new fresh windowsSeven x64 on a new fresh HDD .

my nvidia driver is the 270.51 beta, the one wich make more Gpu working on cuda and opencl .

i have delete the *.clbin , but the crash occurs again .

any help would be appreciate !!

Are there any other programs running that might be taking away GPU resources? If you run a GPU monitoring program like EVGA precision, does is say something meaningful about the GPU RAM usage? Also, what happens if you disable some of the cards?

Best regards,

with the help of "evga precision" and "choose openCL devices" i have isolated 2 card on my 6 wich seems to beeing in the issue.
this is not a software wich take memory .
the difficulty is that the card list order of "choose openCl devices" isn't the same at the nvidia one.

So, with Choose opencl , my cards are 0 1 2 3 4 5 and the one wich seems in the issue are 1 and 4.
I'm back to the 263.xx Nvidia drivers wich working very fine. But the issue still here !!

i will try to replace the card to see if it's an hardware fault .
I hope that's not my card !!

i have replaced 2 cards, and now it's working ...
i'm going to try my 2 faulty card inside an other computer to see if they work or if they are dead ....

the 2 cards seems to work in the other computer ... strange...

BAck to the 270.51 nvidia driver .. everything work fine.

I'm not sure but i think to have lost 2 580GTX !!
