[mythtv-users] Out of spec FSB speeds for a P3?

Hi Piers - Intel locked the multiplier and the cpu just ignores the settings
from the MB. As far as why the settings are there...I don't actually know,
there were, "back in the day"a fair amount of unlocked "engineering samples"
that were around but I doubt if that is the reason. I'm guessing the reason
is legacy, same as why parallel ports, FDs etc. on new PCs.

I'm to lazy today to google you up an answer 8^)

I'm personally running a P3 550 slot 1 at 616 MHz (5.5 x 112 MHz) as a FE
machine but I suspect it might be a bit "light" for a BE machine. You might
get by with using a TV card with hardware encoding and you didn't need to be
watching TV while you're recording something. I'm sure you'll get feedback
from people who've  tried running a FE/BE system on such a machine.
