[mythtv-users] Will moving to DDR-400 memory from DDR-333 improve performance?

[Jason]

I run LFS, so my distro is cut down to the bare minimum, but my backend
on .20 is using 42 megs of ram and mysql is using 96. Out of 512 megs of
RAM, I have over 256 free on a box that has been up and running like mad
for almost a month with 3 tuners active.

My frontend is using 200 megs (512 again, 52 megs free) but was playing
mp3s running goom at the time. It's  also been up for over a month. 
I've actually found .20 to be the most stable myth I've ever run.

The place where you made your stand never mattered,
only that you were there... and still on your feet
