Bug Reports / OpenCL not all VRAM detected
« on: March 06, 2013, 11:57:22 AM »
Hello. I am running the latest pre-release Version 0.9.1 build 1640 (64 bit). In the OpenCL options it lists my 2 Radeon 7970 GHz Edition's as only having 2048MB of memory when they do in fact have 3GB. I also have another machine with a reference 7970 which also displays 2048MB. I can imagine this would make sense on an nVidia card which may have a split 256/128 bit bus, but the Radeon's have a full 384bit bus. It might also make sense why I am only getting 75% GPU utilization. Could this be an issue with the OpenCL drivers? I am using OpenCL drivers 12.4, when I have time I will try with 12.8 and report back.
