Just to throw it out there, surely we've ruled out ECC RAM gets away with worse modules because the checking bit will catch it? Because I actually tried to generate bit flips for a project once and we got nothing. Also a relatively high traffic site, registering a few bit flip variants (so like example.com -> fxample.com) got no hits whatsoever across a year. I keep seeing reports from people with ECC or people who found an available bit flip variant of a top X website, but it never happens to me on normal RAM. I can't imagine that ECC vendors are selling worse RAM with a check bit, but the more I read the more I wonder if maybe we should check just to be sure
