2.5.12 DRAM Timing Control
The subitems in this menu allow you to set the DRAM timing control features. Use the <+> or
<-> keys to adjust the value. To restore the default setting, type [auto] using the keyboard and
press the <Enter> key.
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.

working voltage will decrease proportionally to CPU loading. Higher load-line calibration could
get higher voltage and good overclocking performance, but increases the CPU and VRM
thermal conditions.
Select from Level 1 to Level 8 to adjust CPU power voltage from 0% to 100%.

DO NOT remove the thermal module. The thermal conditions should be monitored.
CPU Voltage Frequency [Auto]
Frequency switching affects the VRM transient response and the thermal component
conditions. Higher frequency gets quicker transient response.
