I did some reading, and i have no idea why my 580 armor won't go above 23 mh/s, while my 570armor can do 30 mh/s

It uses Samsung/Hynix (1: straps K4G80325FB (SAMSUNG) timings and the 2: straps are H5GQ8H24MJ), simliar to the combination for the Nitro+ variants, i used 1 click method on PBE v1.6.6 from jaschaknack, the strap used is
777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17

I reinstalled the Beta blockchain driver.

Still 23 mh/s.

Anyone know why or how to resolve this issue? or i'm just stuck with 23mh card?
