Went from 1402 to 1703m on P5Q-E and now I have something weird.
I'm a underclock/undervolt guy (I know I'm a pariah here ) and until now EPU served me well through many BIOS updates but now something is not right.
I have a profile for idle with FSB 264 and heavy undervolt. If I choose DDR667 in BIOS then FSB remain at 333 and not 264 as it should be. Good thing is that I can OC a little until ~ 3.5GHz.

If i choose DDR800 everything is fine but no OC because memory is drawing me back

EIST/C1E/C-State Tech enabled in BIOS. Any ideas?
BTW I'm not an OC-er and it's fine if I stay at stock speeds but I'm curious why this time EPU have this glitch.
