1) Message boards : Application Code Discussion : CUDA/OpenCL on Mac? (Message 61230) Posted 25 Feb 2014 by Todd Madson Post: Maybe this is in the wrong area but I'm running the following: iMac Corei7 2.8 ghz with 16 gigs of 1333 mhz DDR3 ram. My video card is an ATI Radeon HD 4850 running OpenCL 1.2 (AUG 24 2013 21:03:27) (FULL_PROFILE) with 512 megs of video ram. According to ATI this is an R700 GPU. I'm running BOINC Manager v7.2.39 and when I try to run Milkyway on my videocard I receive the following error: Milkyway@Home: Notice from server ATI GPU R600 (R38xx) does not support OpenCL. So if the manufacturer says it's an R700 but the app says it's an R600 is there any way I can correct the problem to allow my admittedly older video card do any crunching?
