Add --kernel 0 and --xintensity 768 to the launch config.
You need to overclock the memory to around 4300 (+500) and core +150-200. You need more power to avoid trottle on the core clock.
Very very thank you buddy. There is a problem with the my gpu Coreclock error. Yours is currently better than other miners. My last question is I get high mhs on first run. After a few minutes the mhs goes down and stays constant, any solution?
