Hello.

I have i7 970 + 12Gb DDR3 + 2*5850 GPU (W7 64)

I use 14.12 amd drivers

So far he had processed SETI @ home v7 7.07 ( opencl_ati_cat132 ) without problems maximum estimated time 30 minutes and runtime alike.

But lately I take 9 hours and only 50% .

Not all but some if it happens , a few days ago .

Because it happens ?
What would be the solution?

Best regards and thanks.

Sorry for my english i use google translate.

It seems you are suffering from CPU ressources.

Make sure to free at least 2 CPU cores.
One for each GPU.

Thanks for the reply.

The system manages resources only , and gives a use of 0.1 CPU + 1 GPU .

So far he had always done well and doing well .

I`m testing the apps so you better believe me.
As soon the system lacks ressources the OpenCL apps go into stall.
Not only you will avoid such invalids you will also improve speed freeing up one or 2 CPU cores.
