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)
Note: This diagram for example only, it
may not be exactly the same as this
motherboard.
