you can ask for a raise at evaluation time of the year but have to be in a way not to irritate your manager - you can use personal reasons but never say "i saw the payroll list and all others are higher than me" (this way you are implying that your manager has been treating you unfairly, or in a discriminating manner".
if you are really unhappy with the payment, probably changing the job is the only way to get a salary jump.
