Now my average is about 68% for both cards. Can we do 2 wu's at a time? Thanks |

<app_config> <app> <name>milkyway</name> <max_concurrent>6</max_concurrent> <gpu_versions> <gpu_usage>0.33</gpu_usage> <cpu_usage>0.5</cpu_usage> </gpu_versions> </app> </app_config> This is what I am using right now. On average I am getting 75% util. |

how did you get boinc to run with 2 gpus? my boinc (newest version) recognizes 2 gpus ( i have 2x r9 280x), but only uses 1. my app info is: <app_config> <app> <name>milkyway</name> <max_concurrent>2</max_concurrent> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.01</cpu_usage> </gpu_versions> </app> <app> <name>milkyway_separation__modified_fit</name> <max_concurrent>2</max_concurrent> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.01</cpu_usage> </gpu_versions> </app> </app_config> |

<app_config> This should be running 3 units at once, not 2. The "0.33" is one third of the whole so 3 units should be running at one time on each card. To only run 2 units at one time the setting would be "0.5", and to run 4 units at one time the setting would be "0.25". You have to be very careful to NOT overload the card though or it will overheat and it's lifespan will be MUCH shorter. |
