Ultra or Non Ultra Epxo 8rda+

[Neyd3400]

I noticed on CPU-Z that it reads my board a a "nforce Ultra 400". This really surprised me, I had always thought that this board was non-ultra and was further convinced of this my that fact that I could never raise the front bus past 168 regardless of the multi. In fact I could never get my 2200xp past 2.0 GHz regardless of the fbs, mult, voltage. Temps 40-45C.

Is Cpu-Z wrong, does any one know a way to check. I know the Epox 8rda3 is a ultra board.
