I wanted to share my mining config were I get the most out of my card it has been tested with various of cards. This mining config gives about 1.4 to 2.6 more MHash a second to my experience and it is tested on: R9 280X Toxic, Sapphire R9 280X Vapor-X and similar cards.
This config is tested on the following pools:
- DwarfPool (My favorite)
- Nanopool (2nd favorite)
Personally i am using a Sapphire R9 280X Toxic screenshots are attached.Be sure to update it with your own pool info!
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100
