The overid routine has been extensively rewritten. It can be invoked after ivreg or ivreg2, and now produces a variety of test statistics for overidentifying restrictions (Sargan's statistic with and without small-sample correction, Basmann's statistic, and pseudo-F forms of each). The help file is much more informative, with references to the econometric literature. overid now requires Stata version 7.0.

Available from SSC via ssc install overid [,replace].
