It is just interesting that to get maximum performance, you need to use older software revisions. Well said. Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group. GPUUG Website |

GPU Z sees both without complaint as well - happily reports each one's various measures. What am I missing?!!! Regards |

What am I missing?!!! Did the cc_config.xml get lost somehow (or the <use_all_GPUs> therein)? Gruß, Gundolf |

OK. So try all lower case: <use_all_gpus>1</use_all_gpus> F. |

Try to remove <ncpus>2</ncpus> In the past BOINC counted CPUs+GPUs = ncpus I don't know how it is now Here: http://boinc.berkeley.edu/wiki/Client_configuration it is: <use_all_gpus>0|1</use_all_gpus> (lowercase) Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

Nada. Nada. And nada. Tried the gpus parm all lowercase and got rid of the error message in the start up messages. Didn't change anything. Removed the ncpus. Didn't change anything. Removed bot the gpus and ncpus parms and that didn't work. Renamed the cc_config file completely so BOINC wouldn't even see one. Didn't work. Curiouser and curiouser. Regards, |

Nada. Nada. And nada. The only shot left in my locker: - Stop all BOINC processing. - Delete all Nvidia drivers (from Control Panel). - Re-boot into SAFE mode. - Run cc_cleaner to remove all traces of Nvidia drivers from Registry. - Re-load chosen version of Nvidia drivers (I'm still with 191.07 and very happy there). Hopefully, since you are on BOINC 6.10.43, this should not dump existing CUDA cache. If it were mine and that didn't work, the box would be in severe danger of suffering GBH. F. |

The only shot left in my locker: Ahhh - you're right, it is indeed. But now that I re-checked, I really meant Driver Sweeper anyway ;P. Sorry for any confusion that I may have caused. F. |

Very much appreciate all the excellent advice. I will give it a go in the next 24 hours and report any progress. I am certain there's something interesting lurking within all of this. As I say, the old laptop has been a steady performer up until this point. I just had to go meddling with it and install new drivers and a new BOINC and upset the apple cart. Thanks again. Regards, |

Do you keep both GPUs with monitors attached until the issue is solved? Did the re-installed (older) NVIDIA driver had chance to "see" 2 monitors attached? Can you post GPU-Z screenshots of both GPUs? My integrated (no-CUDA) GPU: I use IrfanView & Ploader (very easy to use) http://ploader.net/ "Ploader is a quick image hosting service that allows you to upload, link and share your images with your friends, family, and clients. No account required." I found that the name of the file given by Ploader is its MD5 checksum + .Ext http://ploader.net/files/a7015ed144b9a792061af912d90e33bd.png ___ MD5 of this image is a7015ed144b9a792061af912d90e33bd So if you forget the link you can generate MD5 checksum (I use Total Commander) and make the link "by hand" .

Do you keep both GPUs with monitors attached until the issue is solved? I did. The laptop has its own screen of course and the extra monitor remains attached at the moment. I opened and closed Outlook on it a few times throughout just to keep the electrons moving.
Shall do! I will have that sometime tomorrow (today is work and tonight is a show so I'm AFK on that machine for a bit).
Great tip - thanks. This is the misbehaving machine by the way, http://setiathome.berkeley.edu/show_host_detail.php?hostid=4597934. I looked back to the top of this thread and the original bad boy is now behaving again admirably. Regards and thanks again folks for your generous help, |

Have you tried extending the Desktop onto the second Monitor? then restarting Boinc? Claggy |

Are you sure this laptop has 2 GPUs? Or just one GPU with outputs for 2 monitors? Is the second external monitor digital (DVI) or analog CRT (VGA, D-sub) Digital Visual Interface http://en.wikipedia.org/wiki/Digital_Visual_Interface VGA connector http://en.wikipedia.org/wiki/VGA_connector  - ALF - "Find out what you don't do well ..... then don't do it!" :)  |

Good question (always worth checking the basics) but "unfortunately": yes. They were in fact running quite well until I did a driver update and one disappeared, in BOINC. When I examine it in the device manager its there and confirmed to be running fine. I also bought the laptop with two (and two raided hard drives, etc - it was meant to be a desktop replacement as well as portable). It's been a rock solid cruncher even and never waivered, always running two cuda tasks happily, until I decided to meddle with it. Regards, |

Do you have driver disk (CD, DVD) supplied with the laptop? Try the video driver from that disk. Can you find Video driver on the web site of laptop manufacturer? Sometimes there are proprietary (non-standard) chips or hardware solutions on the laptops which prevent the generic drivers to work correctly. So try to get the driver from the Video Card (or laptop) manufacturer and not from NVIDIA. Programs you can use to find the exact manufacturer/model of the Video Card (and much more): EVEREST http://www.lavalys.com/ SIV 'System Information Viewer' http://www.rh-software.com/ .
