The specifications are wrong!

This procesor, ADH485BIAA5DO, is business class for socket am2+ !

The am2 version is ADH4850IAA5DO.
Their specs may look same, but are diferent and first doen't match for only-am2 motherboards.

Response: AMD product database is not always correct. The 4850B CPUs have a single power plane, and they are limited to 1 GHz HT speed, therefore they are not socket AM2+ processors.
