there are a lot of similare problems with cpu-z. after hours of digging in the database i recognized, that older cpu-z version identfied some cpus different than newer ones.
the "banais" didn't have the 3-digit "numbering".
intel pentium m 1.7ghz -> banais
intel pentium 735 (1.7ghz)-> dothan
so, the error lies in the users which submitted into the wrong category or cpu-z in having problems identifying them correctly.
