Posted 966 days ago by Jake Bennett-Young
Hi there, I recently made upgrades too my 2008 Mac Pro which allowed me to install the gtx 650Ti I had lying around alongside my gtx 680. However too my surprise, doing so gave me the error message 'gtx 680 doesn't support CUDA driver 6.5+' and the event log said neither GPU was used for CUDA or OpenCl. After backdating my drivers too the latest 6.0.x release, full OpenCl usage was restored, but now neither card is even seen as CUDA device! Anyone have any ideas??

Cheers, Jake
