Ugh, this is sounding like that whole EPU vs DES spat between ASUS and Gigabyte several months ago...
- Yes, there's an honest-to-goodness chip labeled "EPU" on the board. (it's on the far north side, next to the CPU Fan connector)
- In practice, it doesn't matter because as far as I know, EPU cannot be enabled when you overclock. (if you try to install the EPU app, it will explicitly tell you this if you try to run it while the system is under overclock)
- I have a hard time imagining someone buying this board and not OCing. There are far cheaper boards in that case, like any of the P43s.
- This feature might be actually useful on the P5Q-EM HDMI (a microATX board that could conceivably used for an HTPC).
