Intel W790 Series BCLK Aware Adaptive Voltage Allows you to set BCLK Aware Adaptive Voltage as enabled or disabled. When it is enabled, pcode will be aware of the BCLK frequency when calculating the CPU V/F curves. This is ideal for BCLK OC to avoid high voltage overrides. Configuration options: [Enabled] [Disabled] Filter PLL Enable sets GPIO8 low (0) to enable the Filter PLL for high BCLK overclocking levels. UnderVolt Protection When UnderVolt Protection is enabled, user will not be able to program under voltage in OS runtime. It is recommended to keep it enabled by default. [Enabled] The item allows BIOS undervolting, but enables UnderVolt Protection in Runtime. [Disabled] No UnderVolt Protection in Runtime. CPU Tj Max Allows you to set CPU Tj Max to adjust TCC Target Temperature. It supports Tj Max in the range of 62 to 115 deg Celsius. Current Limit Override [Disabled] No Current Limit Override. [Enabled] The item allows overriding current limitation in 1/8 A increments. Current Limit This value represents the maximum instantaneous current allowed at any given time. PL1 Power Limit Allows you to configure Package Power Limit 1 in watts. When the limit is exceeded, the CPU ratio will be lowered after a period of time. A lower limit can protect the CPU and save power, while a higher limit may improve performance. PL1 Time Window Allows you to configure the period of time until the CPU ratio is lowered when the Long Duration Power Limit is exceeded. 25

Intel W790 Series
BCLK Aware Adaptive Voltage
Allows you to set BCLK Aware Adaptive Voltage as enabled or disabled. When it is en-
abled, pcode will be aware of the BCLK frequency when calculating the CPU V/F curves.
°is is ideal for BCLK OC to avoid high voltage overrides.
Configuration options: [Enabled] [Disabled]
Filter PLL
Enable sets GPIO8 low (0) to enable the Filter PLL for high BCLK overclocking levels.
UnderVolt Protection
When UnderVolt Protection is enabled, user will not be able to program under voltage in
OS runtime. It is recommended to keep it enabled by default.
[Enabled] °e item allows BIOS undervolting, but enables UnderVolt Protection in
Runtime.
[Disabled] No UnderVolt Protection in Runtime.
CPU Tj Max
Allows you to set CPU Tj Max to adjust TCC Target Temperature. It supports Tj Max in
the range of 62 to 115 deg Celsius.
Current Limit Override
[Disabled] No Current Limit Override.
[Enabled] °e item allows overriding current limitation in 1/8 A increments.
Current Limit
°is value represents the maximum instantaneous current allowed at any given time.
PL1 Power Limit
Allows you to configure Package Power Limit 1 in watts. When the limit is exceeded, the
CPU ratio will be lowered aſter a period of time. A lower limit can protect the CPU and
save power, while a higher limit may improve performance.
PL1 Time Window
Allows you to configure the period of time until the CPU ratio is lowered when the Long
Duration Power Limit is exceeded.
