You can slow network use by simply using 10TX instead of 100TX. It'll
be a network module option.
I've found success with under clocking my EPIA-M10000 for lockups. If I
run it at 80% speed it has no problems with DVD playback. This is not
to discredit the EPIA boards because my setup is in a hot environment,
with slowed cpu fan speed and early drivers.
