[mythtv-users] mATX mobo best for undervolting?

[Yan-Fa Li]

XP-Ms are not clock locked within a certain range.  They only have a 
maximum lock.  For example an XP-M 2500 would probably have a maximum 
lock at around 13.5.  Anything under that is fair game for a multiplier 
if your MB supports it.  This is in contrast to newer XPs which are 
completely clocked locked, and you can only adjust the FSB speed.

The biggest issue with XP-Ms is does your motherboard support 
Multipliers.  Also XP-Ms require less voltage, and the motherboard may 
actually supply too much juice; since XP-Ms are actually cherry picked 
XPs they should run fine however.  If your board doesn't support 
multipliers in the bios you can do workarounds, but they have a certain 
amount of risk:
