Hi guys sorry to bother you again but does anyone know the correct settings for the AMD HD5450 chipset in Lunatic's 0.39 installation as when I first installed it I found it was running ok until, I restarted the PC and it has never worked since even after re-installation! |

You have to make sure OpenCL is activated by the drivers. Use GPUz to see OpenCL is checked. With each crime and every kindness we birth our future. |

Thanks Mike, but as I am still a GPU noob can you tell me where to find GPUz please. |

You can get it from: http://www.techpowerup.com/downloads/SysInfo/GPU-Z/ |

One again thanks guys! I found the OpenGL settings and enabled triple buffering as it was not selected. Will that help in any way? Edit, OpenCL is not active according got GPUz! How do I activate it? |

One again thanks guys! I found the OpenGL settings and enabled triple buffering as it was not selected. Will that help in any way? What i was thinking. You need to install AMD drivers with OpenCL support. The package says OpenCL runtime. What drivers you are using ? Its also shown in GPUz. With each crime and every kindness we birth our future. |

I don't see any machines in your hardware list with a HD5450. When you start BOINC do you see a message like this one in the BOINC event log? Advanced > Event log or CTRL + SHIFT + E 3/10/2012 6:20:51 AM | | ATI GPU 0: ATI Radeon HD 5x00 series (Cedar) (CAL version 1.4.815, 1024MB, 120 GFLOPS peak) If you see "no usable gpus detected" then there is something else afoot.

The HD5450 is not running on mine but my daughters! The Drivers I am running are the automatic updates selected for the card! I get no messages at all so I guess it's just the incorrect install settings plus OpenCL is not active. The driver version is atiumdag 8.930.0.0 / win7 |

Looking through the event log it does say no usable GPU's found! |

Should I download this package? http://developer.amd.com/sdks/AMDAPPSDK/Pages/default.aspx |

Should I download this package? http://developer.amd.com/sdks/AMDAPPSDK/Pages/default.aspx No, you don't need the full developer SDKs (Software Development Kits). Just look for OpenCL or APP inclusive packages on the regular driver download page. |

For win 7 32 bit. http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista32.aspx win 7 64 bit http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista64.aspx Dont forget to uninstall old drivers first and reboot. With each crime and every kindness we birth our future. |

Thanks for the links, now the driver is sorted what about the install settings? As her PC is a core2 Duo running the HD5450 which settings should I use! |

Thanks for the links, now the driver is sorted what about the install settings? As her PC is a core2 Duo running the HD5450 which settings should I use! The install settings for the driver? You can use the default values, which installs everything, if you like. I normally only uncheck one thing on their install. Which has to do with some media something or other that I don't need. In GPU computing updating drivers can be a bad thing. So you might want to disable that for the machine.

Great got OpenCl active now! So the last question for the HD5450 which Astropulse and Multibeam setting should I use for the Lunatics install? |

Great got OpenCl active now! So the last question for the HD5450 which Astropulse and Multibeam setting should I use for the Lunatics install? If you want to edit appinfo use this. MB -period_iterations_num 20 -instances_per_device 2 -no_gpu_lock count 0.5 AP -instances_per_device 2 -unroll 6 -ffa_block 4096 -ffa_block_fetch 2048 count 0.5 should work nicely.

You'd better start over. Clean out the old drivers by uninstalling and using driver sweep, then reinstall the fresh ones. ATI has a habit of not removing all its old drivers which will cause all sorts of running problems for crunching In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

Great got OpenCl active now! So the last question for the HD5450 which Astropulse and Multibeam setting should I use for the Lunatics install? If the card has a Max work group size of 256 or greater then you probably want to use these options in the installer. If this card is one of the ones with a Max work group size <256 then you would uncheck MultiBeam and choose the other AP option. To find out what it supports you would open a command prompt and type clinfo. Then scroll up to find a section that looks something like this: Platform Name: AMD Accelerated Parallel Processing Number of devices: 2 Device Type: CL_DEVICE_TYPE_GPU Device ID: 4098 Board name: AMD Radeon HD 6800 Series Max compute units: 14 Max work items dimensions: 3 Max work items[0]: 256 Max work items[1]: 256 Max work items[2]: 256 Max work group size: 256 SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

it's not necessarily the OpenCl that is going to crash the work either. For ATI driver installs I tend to be a bit over zealous and anal about their installation. It saves time later trying to figure out what failed In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |
