	I've gotten a couple of private messages about one of my machines, that seems to be producing mostly junk: errors and invalid results. At first I thought this might be due to the video card; my driver locks up periodically and resets the card and driver on me. So I suspended GPU usage, thinking that might solve it, but alas, it seems not. What are the steps to take in order to begin diagnosing the problem? This problem relates to the following machine: http://setiathome.berkeley.edu/show_host_detail.php?hostid=5889577 ____________

	Right now , it appears that disabling GPU use has stopped your error production, however it certainly has not solved your problem. computer 5889577 wrote: CPU type GenuineIntel Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz [Family 6 Model 42 Stepping 7] Number of processors 4 Coprocessors NVIDIA GeForce GTX 560 Ti (2047MB) driver: 301.42 Operating System Microsoft Windows 7 Ultimate x64 Edition, Service Pack 1, (06.01.7601.00) BOINC version 7.0.28 Memory 8162.12 MB Cache 256 KB Measured floating point speed 3403.72 million ops/sec Measured integer speed 12157.97 million ops/sec Average upload rate 36.78 KB/sec Average download rate 369 KB/sec Average turnaround time 0.27 days Application details Show Tasks 1063 Number of times client has contacted server 17044 Last contact 21 Oct 2012 application details clip wrote: SETI@home Enhanced 6.10 windows_intelx86 (cuda_fermi) Number of tasks completed 7390 Max tasks per day 100 Number of tasks today 0 Consecutive valid tasks 0 Average processing rate 248.75388612667 Average turnaround time 0.24 days Looks like your problem is with the cuda fermi application from seti@home. Try to obtain and install an optimized gpu application. if this resolves your problem , you will also enjoy a higher RAC for doing it. upon further inspection it appears your gpu is overclocked , slowing it back down should solve your issue. nvidia specs for gtx 560ti wrote: CUDA Cores 384 Graphics Clock (MHz) 822 Processor Clock (MHz) 1645 ID# 5889577 randomly chosen invalid task wrote: Device 1 : GeForce GTX 560 Ti totalGlobalMem = 2147155968 sharedMemPerBlock = 49152 regsPerBlock = 32768 warpSize = 32 memPitch = 2147483647 maxThreadsPerBlock = 1024 clockRate = 1840000 totalConstMem = 65536 major = 2 minor = 1 textureAlignment = 512 deviceOverlap = 1 multiProcessorCount = 8

This problem relates to the following machine: http://setiathome.berkeley.edu/show_host_detail.php?hostid=5889577 Your CPU processing looks fine, but probably most of the tasks which have already been reported from GPU processing will end up being invalid. They're waiting for results to be reported from another host, then the Validator will render its judgement. The 560Ti cards are good but somewhat temperamental, see post 1240004 by jason_gee for some things to check. Joe

	What brand and model of 560Ti is that?

	Easiest fix for the 560ti will be Jason's app when it goes live soon. I had an EVGA 560ti that loved nothing more than to make my life miserable. ____________ Executive Director GPU Users Group Inc. - brad@gpuug.org

I had the same thing going-on, if you remember. It took more than Lunatics' to fix mine. One card went back for repair and the other I flashed the BIOS myself (it was available on Gigabyte's website, I'm not saying I wrote my own BIOS). <knocking wood> They do seem to be better. But one card or another will let me down from time-to-time and start spouting junk.
