pcace Posted December 15, 2010 Share Posted December 15, 2010 Hi, im Using a hackintosh macosx 10.6.5 retail install. (see Signature) right now i want to use the full power of the GTX260 including Double-Precision support. Has anyone an Idea, how i can do that? I Know that the GTX 260 has that support (http://en.wikipedia.org/wiki/GeForce_200_Series). I tested the OpenCL Speed with "OpenCL2_bench": OpenCL2_Bench_V025 ; exit;........................................................... .................. OpenCL Bench V 0.25 by mitch ........... ...... C2D 3GHz = 12 sec vs Nvidia 9600GT = 0,93 sec ...... ... time results are not comparable to older version! ..... ........................................................... Number of OpenCL devices found: 3 OpenCL Device # 0 = GeForce GTX 260 Device 0 is an: GPU with max. 1242 MHz and 24 units/cores Now computing - please be patient.... time used: 0.349 seconds OpenCL Device # 1 = GeForce 9800 GT Device 1 is an: GPU with max. 1500 MHz and 14 units/cores Now computing - please be patient.... time used: 5.840 seconds OpenCL Device # 2 = Intel® Core i7 CPU 920 @ 2.67GHz Device 2 is an: CPU with max. 3800 MHz and 8 units/cores Now computing - please be patient.... time used: 1.418 seconds Now checking if results are valid - please be patient.... Validate test passed - GPU results=CPU results logout [Prozess beendet] And oclinfo sais that there is no Doubleprecision support with my GTX260: --> so no "cl_khr_fp64" 1 OpenCL platform found!
