RX 580 +  win10 + blockhain driver 23 august + AB 18 + Claymore v10.0

if I add values in and use  

-cclock  
-mclock  
-cvddc
-mvddc

which works and stable? or still voltage resetted ?

is overclocking and/or voltage working with 580's?

if works, is still needed afterburner?

"Supports latest AMD 4xx cards only in Windows."   ... and 580's?

Thank you for reply.
