thatk you all guys !
actually it was missing " -vert" in my batch file!
Now my 0.5.3 it's started but it works at only 275 Khash per GPU (280x).
It 's less than half of scrypt hash rate! Don't you seem?
with Cgminer i get 750 Khash per GPU.
When you mine Scrypt-N you get only Half Kh/s than normal Scrypt mining.
Play with your settings till you get 350+ kh/s also increase intensity to 20.
