BIOS Setup
Spread Spectrum
Ths functon reduces the EMI (Electromagnetc Interference) generated by modulatng
clock generator pulses.
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.
The greater the Spread Spectrum value s, the greater the EMI s reduced, and the
system wll become less stable. For the most sutable Spread Spectrum value, please
consult your local EMI regulaton.
Remember to dsable Spread Spectrum f you are overclockng because even a slght
jtter can ntroduce a temporary boost n clock speed whch may just cause your
overclocked processor to lock up.
Vdroop Control
Ths tem s used to select the VDroop control mode.
CPU Core OCP Expander
Ths tem s used to expand the lmtaton of CPU Over Current Protecton. The hgher
expandng value ndcates less CPU protecton. So please adjust the CPU voltage
carefully f needed.
CPU Core Engne Speed
Ths tem allows you to ncrease the PWM workng speed to stablze CPU Core voltage
and mnmze rpple range. Increasng the PWM workng speed wll cause hgher
temperture of MOSFET. So please make sure a coolng soluton s well-prepared for
MOSFET before you ncrease the value.
CPU Core Voltage/ DRAM Voltage/ GPU Voltage/ System Agent Voltage (SA)/ CPU
PLL Voltage/ DDR_VREF_CA_A/ DDR_VREF_CA_B/ DDR_VREF_DA_A/ DDR_VREF_
DA_B/ PCH 1.05
These tems are used to adjust the voltage of CPU, Memory, GPU and chpset.
