I really wasn't expecting that considering my last card did. You can disregard this post, unless anyone has a workaround. Seems like I need to dedicate my NVIDIA card more instead, unless I can manage to reinstall my last card simultaneously.
2) Message boards : Number crunching : Computation Errors (Message 54168) Posted 26 Apr 2012 by Alex Fox Post: Hey, guys. This is my first post on these forums but I'm an experienced BOINC user. I've been running MH@Home seperation tasks for a while on my 4870, but I recently upgraded to a 6850. With my 4870, I was able to run the WUs under an anonymous platform app_info.xml. Once upgrading, all of the tasks I've tried have failed instantly on starting. I decided to remove the app_info and try to request work from the server and here's the message I get: 4/26/2012 8:15:46 AM \| Milkyway@Home \| update requested by user 4/26/2012 8:15:49 AM \| Milkyway@Home \| Sending scheduler request: Requested by user. 4/26/2012 8:15:49 AM \| Milkyway@Home \| Requesting new tasks for ATI 4/26/2012 8:15:50 AM \| Milkyway@Home \| Scheduler request completed: got 0 new tasks 4/26/2012 8:15:50 AM \| Milkyway@Home \| No tasks sent 4/26/2012 8:15:50 AM \| Milkyway@Home \| Message from server: GPU lacks necessary double precision extension On start-up 4/26/2012 8:13:54 AM \| \| ATI GPU 0: AMD Radeon HD 6800 series (Barts) (CAL version 1.4.1703, 1024MB, 991MB available, 3149 GFLOPS peak) 4/26/2012 8:13:54 AM \| \| OpenCL: ATI GPU 0: Barts (driver version CAL 1.4.1703 (VM), device version OpenCL 1.1 AMD-APP (898.1), 1024MB) 4/26/2012 8:13:54 AM \| \| ATI GPU is OpenCL-capable Any idea why I'm not able to use MH@Home? Perhaps a driver issue? This is an isolated issue with just this project.
