tWRDRDD
Specfies the wrte-to-read delay of dfferent ranks on the same/ dfferent DIMM(s).
tRWSR
Specfies the read-to-wrte delay of same rank.
GT OverClockng
Ths tem allows you to enable/ dsable the overclockng of ntegrated graphcs.
GT Rato
Ths settng controls the rato of ntegrated graphcs frequency to enable the ntegrated
graphcs to run at dfferent frequency combnatons.
Adjusted GT Frequency
It shows the GPU frequency. Read-only.
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.
Dgtal Compensaton Level
Ths tem s used to select the current compensaton speed when the MOS phases be
changed. For overclockng or full-loadng of system, t s recommended ths field set to
[hgh]. Please note that overclockng behavor and stablty s not guaranteed.
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.
