Frequency Chart
Some of the most recent boards have shipped with three switches
instead of the previous two. This allows our faster boards to reach
speeds above 360 Mhz by using bus speeds above the previous 45 Mhz
limit. Individual motherboards will have limits as to how fast they
can go. Please do not call Tech Support about speeds higher than the
ones recommended in your manual.
