I have R9 280x not overclocked. I started mining with claymore and Nicehash pool. Today most of the time I'm mining at 13mhs, but at unregulated time I see the mhs is raised to 25mhs in Nicehash pool. And the temperature of the card is raised to 80 degrees. At 13mhs the temp is 67 degrees. Why is that happen? Who control my card at how much mhs will mining?
What could be the reason?
My configuration bat file is:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
