For high frequency operation, especially
overclocking, layout is the most important
factor to make sure chipset and CPU
working in stable condition. The layout of
this motherboard implements AOpen’s
unique design called “ Frequency Isolation
Wall”. Separating each critical portion of
motherboard into regions where each
region operates in a same or similar
frequency range to avoid cross talk and
frequency interference between each
region’s operations and condition. The
trace length and route must be calculated
carefully. For example, the clock trace
must be equal length (not necessarily as
short as possible) so that clock skew will
be controlled within few a pico second
(1/10
12
Sec)

may not be exactly the same as this
motherboard.
