Auto Detect DIMM/PCI Clk
This item automatically detects the
clock speeds of the system memory
installed
as well as the PCI interface.
The
options available are Enabled
and Disabled. The default setting
is
Enabled
.
Speed Spectrum
This item
directly relates
to the
EMI performance of the whole system.
When
enabled,
all
system
clocks
run
at
slower
speeds
thereby
decreasing
the
electromagnetic
interference
to
the
surrounding
environment. Disabling this item improves
the system performance but
simultaneously
increase the EMI.
The default
setting is
Disabled.
