oclHashCat-plus64 MD5(unix) cracking help

[sangiiin]

tanq for your replay.

because i cant understand mask chars ...!
i know ?l is lowercase , ?u is uppercase , .....
but i dont know , how can write correct mask ...

but it isn't the real problem !
my speed is 60180/s for mask attack..
i used ?l for example ...

on md5 (-m 0) i have M/s speed
but on md5(unix) i have this speed , that is not a good speed for bruteforce i think
with this speed i just can check 5digit low-letter in 30 min !
this time will be len(?l)*30min for 6digits only

can i have more speed with my gpu and no clustering?
i can support temperature ...
