BIOS Setup
▶ Spread Spectrum
Ths functon reduces the EMI (Electromagnetc Interference) generated by modulatng
clock generator pulses.
Important
• If you do not have any EMI problem, leave the settng at [Dsabled] for optmal system
stablty and performance. But f you are plagued by EMI, select the value of Spread
Spectrum for EMI reducton.
• The greater the Spread Spectrum value s, the greater the EMI s reduced, and the
system wll become less stable. For the most sutable Spread Spectrum value, please
consult your local EMI regulaton.
Remember to dsable Spread Spectrum f you are overclockng because even a slght
•
jtter can ntroduce a temporary boost n clock speed whch may just cause your
overclocked processor to lock up.
▶ Vdroop Control
Ths tem s used to select the VDroop control mode.
▶ CPU Core OCP Expander
Ths tem s used to expand the lmtaton of CPU Over Current Protecton. The hgher
expandng value ndcates less CPU protecton. So please adjust the CPU voltage
carefully f needed.
▶ CPU Core Engne Speed
Ths tem allows you to ncrease the PWM workng speed to stablze CPU Core voltage
and mnmze rpple range. Increasng the PWM workng speed wll cause hgher
temperture of MOSFET. So please make sure a coolng soluton 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 chpset.
▶ Current CPU Core Voltage/ Current DRAM Voltage/ Current GPU Voltage
These tems show current CPU/ DRAM/ GPU voltage. Read-only.
▶ Overclockng Profiles
Press <Enter> to enter the sub-menu.
▶ Overclockng Profile 1/ 2/ 3/ 4/ 5/ 6
Press <Enter> to enter the sub-menu.
▶ Set Name for Overclockng Profile 1/ 2/ 3/ 4/ 5/ 6
Gve a name by typng n ths tem.
▶ Save Overclockng Profile 1/ 2/ 3/ 4/ 5/ 6
Save the current overclockng settngs to ROM for selected profile.
▶ Load/ Clear Overclockng Profile 1/ 2/ 3/ 4/ 5/ 6
Load/ Clear the stored profile settngs from ROM.
