The real part of each term in your sum is x^-0.5, thus for the first
omitted term it is 1/sqrt(501), which is greater than 1/23, so you
shouldn't expect much in the way of convergence. To get anything close
to 0, you'd probably need an upper limit of 1000000 or so, which is
why this method isn't practical for calculating values of zeta near
the critical line. The Euler-MacLaurin expansion converges much faster.
