Setup Option Description
TDP Power Limit
Override (Watts)
Defines the maximum power (in watts) that can be used by the processor when Turbo
Mode is active. If the processor exceeds this value, Turbo mode will be disengaged
and the maximum non-Turbo ratio will be used until the power level average drops
below the limit. This parameter allows you to set the maximum wattage in order to
prevent exceeding the cooling capability of your thermal solution. If the cooling
capability of your thermal solution is exceeded, processor throttling will occur.
CPU VR Current
Limit Override
Setting this to Enable will under report the actual TDC current used in the TDC and
TDP Overrides.
Individual Core
Ratio Adjustment
When this setting is enabled, all core ratio limits can be reset to the same value by
making a single adjustment. When this is disabled, each of the core ratios are
adjusted individually.
6-Core Ratio
Limit
Sets the core multiplier to be used when six processor cores are in use.
5-Core Ratio
Limit
Sets the core multiplier to be used when five processor cores are in use.
4-Core Ratio
Limit
Sets the core multiplier to be used when four processor cores are in use.
3-Core Ratio
Limit
Sets the core multiplier to be used when three processor cores are in use.
2-Core Ratio
Limit
Sets the core multiplier to be used when two processor cores are in use.
1-Core Ratio
Limit
Sets the core multiplier to be used when one processor core is in use.
IOH Core Voltage
Override
This setting allows the user to increase the voltage to the IOH.
QPI Data Rate Allows the QPI data rate to be selected. Some processors have the QPI data rate
locked at 4.8 GT/s and the QPI data rate cannot be changed.
PCI Express Bus
Frequency
Allows the user to change the frequency of the PCI express bus.
