The following items appear only when Voltage Floor Mode is set to [Dynamic].
Ceiling Low VMax
The lowest maximum voltage point that maps to Ceiling Hot Temp should the
processor temperature move to hotter or equal to Ceiling Hot Temp. Use the <+> or
<-> to adjust the value. The values range from 0.000V to 3.000V with an interval of
0.00625V. [Auto] is 1.20V.
Configuration options: [Auto] [0.00000] - [3.00000]
Ceiling Hot Temp
The hottest temperature point that maps to Ceiling Low VMax should the processor
temperature move to hotter or equal to Ceiling Hot Temp. Use the <+> or <-> to adjust
the value.
[Auto] is 88C.
Configuration options: [Auto] [0] - [255]
Ceiling High VMax
The highest maximum voltage point that maps to Ceiling Cold Temp should the
processor temperature move to colder or equal to Ceiling Cold Temp. Use the <+> or
<-> to adjust the value. The values range from 0.000V to 3.000V with an interval of
0.00625V.
[Auto] is 1.450V.
Configuration options: [Auto] [0.00000] - [3.00000]
Ceiling Hot Temp
The coldest temperature point that maps to Ceiling High VMax should the processor
temperature move to colder or equal to Ceiling Cold Temp. Use the <+> or <-> to
adjust the value.
[Auto] is 65C.
Configuration options: [Auto] [0] - [255]
CPU VRM Switching Frequency
Sets the VRM switching frequency. VRM switching frequency affects transient
response and VRM component temperatures. Setting a higher switching frequency
will result in better transient response at the expense of higher VRM temperatures.
Active cooling of the VRM heatsink is recommended when running high CPU voltage
and high load-line calibration values.
Configuration options: [Auto] [Manual]
DO NOT remove the thermal module. The thermal conditions should be monitored.
The following item appears only when CPU VRM Switching Frequency is set to [Auto].
VRM Spread Spectrum
Reach the magnitude of peak noiseq from the VRM. When enabled, peak noise is
reduced. Disable this setting when overclocking.
Configuration options: [Auto] [Disabled] [Enabled]
