I'm kinda dull...what would the purpose of these chips be (different than ES or mass market)? For testing for boardmakers, etc.?
While for the most part, AMD OPNs follow a somewhat structured nomenclature for models numbers, there are sometimes a few models which get unusual model numbers assigned to them at the time of pre-release and then get changed to a model number which is more "normal". For example, take a look at these Opties I had quite awhile back. Look closely @ the OPNs - they're marked as 264's and 266's:



Now try to find those on AMD's proc. listings Ultimately, when these cpu's were released in their retail form, they were released as Opteron 270's and 275's. Hopefully that sort of helps in clearing things up a bit.
