DL165 G7 quickspecs are all wrong.

According to these quickspecs for DL165 G7:

http://h17007.www1.hpe.com/docs/iss/4AA0-6717ENW%20DL165%20Data%20Sheet.pdf

http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c02074307-5.pdf

It clearly says the Opteron 6276 is supported, however after buying 10 brand new processors for 5 servers we have, we discovered that non of the 62XX series are supported!

In this particular specsheet (which is almost identical as above, System Board is the same 603887-001 ), lists on page 25 AMD processor 6164HE  as the maximum supported:

So which one is correct? are two different system boards? or it's an error from HPE?
