according to this link if the chip could do x11,x13,x15. what would it take to design for x-17. then you would have all the necessary pieces to do x-11,x-13,x-14,x-15,x-17 -- http://www.getpimp.org/community/blog/144-what-are-all-these-x11,-x13,-x15-algorithms-made-of.html. also x-14 has same components as x-15, why cant these miners do it too? what are your thoughts?
