installed. Press Enter to display the individual configuration screen of installed SATA drive(s).
Clock to All DIMM/ When enabled, clock signals will be sent to the PCI and memory slots
PCI/PCIE regardless of whether the slot is occupied or not.
Spread Spectrum When the mainboard's clock generator pulses, the extreme values of the
pulses creates EMI (electromagnetic interference). Set this field to Enabled
to reduce this EMI level. This reduces interference problems with other
electronics in the area.
Note: Remember to disable the Spread Spectrum feature if you are
overclocking. A slight jitter can introduce a temporary boost in clock speed
causing the overclocked processor to lock up.

Multiplier EIST function is disabled.
Bootup Num-Lock If you set this item to On, the keyboard Num Lock key will be active when
the computer boots up.
