Hello,

I have been a long time Seti@home user and just built a new computer.

CPU Intel Core i7-3930K Sandy Bridge-E
Motherboard ASUS P9X79 PRO LGA 2011
Memory CORSAIR DOMINATOR 32GB
Video Card EVGA GeForce GTX 680 driver: 306.97
OS Microsoft Windows 7 Professional SP1 64-bit
Boinc version 7.0.28
Seti@home version Just added last week

My old machine is working just fine with from what I can tell the same Boinc settions.

As the title states I am getting "computation error" for ALL work units when I use the GPU but not when I use the CPU. WHen I select the option to not use the GPU everything seems to work but much slower that it could. Is there any disgnostic program I can run on the video card to see if the issue is with it or the CUDA operations?

I would be very thankful for any assistance that you may give.

With your computers hidden, you will have to give a link to one of the tasks that went wrong, as else it's impossible for any of us to go guess what your problem could be. Or just unhide your computers.

Just based on the driver and card I would bet on the second problem in this thread.
