Overclockng
Current CPU / DRAM Frequency
These tems show the current clocks of CPU and Memory speed. Read-only.
CPU Base Frequency
Ths tem s used to adjust the CPU base frequency (n MHz).
Adjust PCI-E Frequency (MHz)
Ths 󰘰eld allows you to select the PCI-E frequency (n MHz).
OC Gene Button Operaton
Ths 󰘰eld s used to enable/ dsable OC Gene functon.
Spread Spectrum
When the manboard’s clock generator pulses, the extreme values (spkes) of the pulses
create EMI (Electromagnetc Interference). The Spread Spectrum functon reduces the
EMI generated by modulatng the pulses so that the spkes of the pulses are reduced
to 󰘱atter curves.
Important
If you do not have any EMI problem, leave the settng at [Dsabled] for optmal system
stablty and performance. But f you are plagued by EMI, select the value of Spread
Spectrum for EMI reducton.
