Our bad. Happened due to some excess epic fail in our hardware database, with someone typoing some stuff when adding & modifying data (no names...). Thanks for the reports.
A fix has been applied, should affect all benchmark submits (3DMark 06, 3DMark Vantage, PCMark 05, PCMark Vantage) that experienced this. Problem appears to have been limited to users with certain models of Phenom II X4 and X6. If you still experience issues, please post in this thread detailing your hardware.
