Can somebody, who is using the latest nicehash windows build sgminer_v5 (sgminer-5.0-pre-release-2014-06-25-win32.zip) with 14.6 beta drivers , please check if the gpu-engine/gpu-memclock options are working with this build as expected ?
For me, the latest windows build, completely ignores the core/memory clock settings from config file, the GPU boost mode default values are used instead (1070/1550MHz for the given R9-280X cards). I'm unable to change the values from sgminer GPU menu (Shift+G) as well. thanks
