TVB Voltage Optimizations

This item controls thermal based voltage optimizations for processors that implement

the Intel Thermal Velocity Boost (TVB) feature.

Configuration options: [Auto] [Enabled] [Disabled]

TVB Ratio Clipping

This service controls Core frequency reduction caused by high package temperatures

for processors that implement the Intel Thermal Velocity Boost (TVB) feature. It is

required to be disabled for supporting overclocking at frequencies higher than the

default max turbo frequency. Uses Overclocking Mailbox command 0x18/0x19.

Configuration options: [Auto] [Enabled] [Disabled]

V-Max Stress

If this item is set to [Enabled], Frequency may be clipped if the max voltage on the

silicon is too high. Frequency will not be clipped if disabled.

Configuration options: [Auto] [Enabled] [Disabled]

V/F Point Offset

Offset Mode Sign 1-8

Configuration options: [+] [-]

V/F Point 1-8 Offset

Configuration options: [Auto] [0.001] - [0.999]

Realtime Memory Timing

This item allows you to enable or disable realtime memory timing.

Configuration options: [Enabled] [Disabled]

FCLK Frequency for Early Power On

This item allows you to set the FCLK Frequency for Early Power On.

Configuration options: [Auto] [Normal (800 MHz)] [1GHz] [400 MHz]

1 GHz is not supported for ULT/ULX SKUs.

Initial BCLK Frequency

This item allows you to set a different BCLK value during POST. May be useful for

setting a lower BCLK in scenarios where memory training is not stable at a higher

BCLK (a large frequency gap between BCLK Frequency and Initial frequency is not

recommended). Applies the same value as BCLK Frequency if left at default. Use the

<+> or <-> to adjust the value. The values range from 40.0 MHz to 650.0 MHz.

BCLK Amplitude

This item allows you to set the magnitude of the reference BCLK supplied to the

processor. Higher values may improve overclocking stability.

Configuration options: [Auto] [700mV] - [1000mV]

BCLK Slew Rate

This item allows you set the speed at which the base clock rises or falls. Set a high

value for overclocking stability.

Configuration options: [Auto] [1.5V/ns] [2.5V/ns] [3.5V/ns] [4.5V/ns]
