Table 1. Processor Overrides
Setup Option Description
CPU Voltage Override Options
Static CPU Voltage
Override
Overrides the voltage requested by the processor
and applies a static voltage. This option disables
the dynamic voltage control of the processor.
Dynamic CPU Voltage
Offset (mV)
Maintains the dynamic VID control of the
processor which scales the output voltage around
the selected base voltage automatically.
CPU Vreg Droop Control Changes the amount of voltage drop applied when
the processor draws maximum current. Choosing
the “Low V-droop” option causes the desktop
board to supply voltage with no drop even at
maximum processor current draw.
Processor Performance Options
Note: All multiplier values listed below are applied to the single 133 MHz Host
clock.
Maximum Non-Turbo Ratio Sets the default multiplier that the processor will
use. Useful when increasing the host clock
frequency above 133 MHz. The maximum
multiplier is dependent on the processor installed.
CPU Idle State Enables CPU low power states. High performance
mode will always run the CPU at the chosen
multiplier. Low power mode allows EIST to
function.
Turbo Mode Override Options
TDC Current Limit
Overrride (Amps)
TDP Power Limit Override
(Watts)
Displays the default current limit and the
processor rated TDP.
Turbo Mode Multipliers
4-Core Ratio Limit
3-Core Ratio Limit
2-Core Ratio Limit
1-Core Ratio Limit
Display’s Maximum CPU performance given
adequate thermal margin, voltage, and current
applied while not in C3 or C6 power states.
