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
