It should be noted however,  that the odds of you finding a mobo that
has good undervolting support and bad clocksetting support is very
slim.  The other way around is very common.  Personally, I'm a big fan
of my SOLTEK 75MIV2-L even though I had to order it from Canada.  It's
got a lot of control open in the bios for clock speeds, voltage, and
temp settings.
