Well it would be somewhat difficult to observe, since it would manifest as the inability to crack some very small fraction of hashes. And the driver would likely crash well before someone can get it to that point.
But what I'm hoping to do is build OC profiles for every hash of interest where the GPU is taken to its limit with quite a few driver overrides. Perhaps it is as you say as the GPU will just start hanging well before it would start making hashing mistakes, but I was somewhat hoping there was a tool to be sure.
Various hashes engage the GPU in various pathways, so it could be technically possible to OC a GPU past what anyone could imagine.
I have seen it done with some machine learning algorithms, the GPU was overclocked by over 80%! and it was stable and correct.
