Hi. I have two GTX 560 in SLI, but Boinc see only one GPU. How i can enable second GPU?

By default BOINC uses only the best GPU. Even two gpus of the same make and model, can still differ. BOINC decides which gpu is best based on these factors, in decreasing priority): - compute capability - software version - available memory - speed And due to the memory detection bug that's in 7.0.28, your first 560 Ti shows a considerable larger amount of available memory than the second, so it's better. 20.10.2012 19:37:38 | | NVIDIA GPU 0: GeForce GTX 560 Ti (driver version 306.97, CUDA version 5.0, compute capability 2.0, 1280MB, 8381598MB available, 1312 GFLOPS peak) Either upgrade to BOINC 7.0.36 (links available in post 45639 in the BOINC 7.0 Change Log thread), which has this bug fixed for most systems out there, or use the <use_all_gpus/> switch in cc_config.xml <cc_config> <options> <use_all_gpus>1</use_all_gpus> </options> </cc_config> |

Hi Jord, I am having the same problem trying to get BOINC to use 2 GPUs on Seti. The first is an older GE Force 9600 and the new on is a GTX 650TI. I have tried adding the option to my cc_config.xml as well as downloading and installing 7.0.36. I have a monitor connected to both video cards. Is there anything else I can try? Thanks in Advance Gary |

Please post your Boinc startup messages from the Event log, the first 20 to 30 lines will do, Claggy |

Did you modify the correct cc_config.xml file (the one generated by BOINC in your data directory for the <exclusive_app> instructions)? Gruß, Gundolf Computer sind nicht alles im Leben. (Kleiner Scherz) ![]() |

I have the same problem, even with: That entry either hasn't been added to the right cc_config.xml (in the correct location), or you haven't restarted Boinc, on my T8100: 30/03/2013 10:09:40 | | Starting BOINC client version 7.0.59 for windows_x86_64 Claggy |

I updated to version 7.0.59, but I get the same log, it won't use my device 0 Please give the 7.0.59 log. That it wasn't used in 7.0.28 was due to a memory detection bug, that was fixed in a later version. BOINC only uses the best GPU according to these priority points: 1 - compute capability 2 - software version 3 - available memory 4 - speed When one of the identical GPUs is 'detected' to have 8381237MB over the other one only having 2048MB, then the first one is superior and used. Now, 7.0.59 will have the fix for the memory detection going wrong, and will ignore the <use_all_gpus/> setting wherever it is. But if you state it still doesn't work, we will want to see its new messages, perhaps that something else of the 4 priority points changed. |

OK, adjusted the MB values, which is all that needed to be adjusted. The rest of the post is still correct. But thanks, shows me I shouldn't be around here until well awoken around 10pm... :P |

Time lapse... did not see claggy's reply. Good the newest client when having the cc_config.xml generated by the host via the <exclusive_app> screen, sorts the tags alpha, so expect <use...> to be towards the end of the <options> section :D Coelum Non Animum Mutant, Qui Trans Mare Currunt |
