maybe this is a silly question but im new to this and had to ask. im running dual nvidia graphics cards that are SLI'd. when i look at my tasks it says its only using one nvidia gpu and under my account info its only listing the one 1gb card when im running 2 1gb cards. my actual question is it actually using both and not reporting it or if it isn't there a way i can make it use both so i can crunch faster? |

my actual question is it actually using both ... Check the GPU load and temperature for both GPUs with some tool http://rh-software.com/ http://www.techpowerup.com/gpuz/ http://www.ozone3d.net/gpu_caps_viewer/ http://event.msi.com/vga/afterburner/download.htm http://www.almico.com/speedfan.php The app itself is detecting both: http://setiathome.berkeley.edu/result.php?resultid=2786484181 setiathome_CUDA: Found 2 CUDA device(s): Device 1 : GeForce GTX 560 Ti totalGlobalMem = 1073414144 sharedMemPerBlock = 49152 regsPerBlock = 32768 warpSize = 32 memPitch = 2147483647 maxThreadsPerBlock = 1024 clockRate = 1800000 totalConstMem = 65536 major = 2 minor = 1 textureAlignment = 512 deviceOverlap = 1 multiProcessorCount = 8 Device 2 : GeForce GTX 560 Ti totalGlobalMem = 1073545216 sharedMemPerBlock = 49152 regsPerBlock = 32768 warpSize = 32 memPitch = 2147483647 maxThreadsPerBlock = 1024 clockRate = 1800000 totalConstMem = 65536 major = 2 minor = 1 textureAlignment = 512 deviceOverlap = 1 multiProcessorCount = 8 setiathome_CUDA: CUDA Device 1 specified, checking...

i installed techpowerup gpuz and while i was crunching its saying only one of my cards has a load on it. is there a way to make them share or do i just not have my cards running right? |

after looking at the gpuz a little closer i noticed that i appearently was tired when finishing the setup on my desktop cause i nver enabled SLI on the graphics cards lol. |

Try also SIV (the first link) - it shows much more info  - ALF - "Find out what you don't do well ..... then don't do it!" :)  |
