I have an Armor rx570 8gb(Samsung). 

I have tried several setups and cannot get above 28mh. The BIOS is not modded. My script is:

PhoenixMiner.exe -epool  us1.ethermine.org:4444 -ewal xxx.xxx -acm -gpus 1 -rxboost 1 -tstop 70 -r 1 -tt 60 -cclock 1150 -cvddc 850 -mclock 2100 -mvddc 850

Does anyone have any suggestions to get more?  I see people bragging about getting 32-34mh but if I try to boost more I start getting blue screens....

Thanks
