CPU BCLK Amplitude
This item allows you to set the magnitude of the reference BCLK supplied to the
processor. Higher values may improve overclocking stability.
Conguration options: [Auto] [700mV] [800mV] [900mV] [1000mV]
CPU BCLK Spread Spectrum
This item allows you to reduce the EMI. Disable to get more accurate base clocks.
Conguration options: [Auto] [Disabled] [Enabled]
CPU BCLK Frequency Slew Rate
This item allows you set the frequency update rate. Lower values speed up clock
changes.
Conguration options: [Auto] [Ultra fast] [Fast] [Normal] [Slow]
CPU 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.
Conguration options: [Auto] [1.5V/ns] [2.5V/ns] [3.5V/ns] [4.5V/ns]
PCIE/DMI Slew Rate
This item allows you set the speed at which the base clock rises or falls. Set a high
value for overclocking stability.
Conguration options: [Auto] [1.5V/ns] [2.5V/ns] [3.5V/ns] [4.5V/ns]
CPU AUX1 Voltage
This item allows you to congure the voltage for the CPU AUX1.
Conguration options: [Auto] [0.000V] – [2.700V]
CPU AUX2 Voltage
This item allows you to congure the voltage for the CPU AUX2.
Conguration options: [Auto] [0.000V] – [2.700V]
CPU Input Reset Voltage
This item allows you to congure the input voltage for the CPU by the external voltage
regulator when reset.
Conguration options: [Auto] [0.800V] – [2.700V]
VTTDDR Voltage (CHA, CHB)
This item allows you to congure the termination voltage for memory channel A and
channel B. 50% of DRAM voltage is default. A setting of Auto scales this setting at
50% of the applied DRAM voltage.
Conguration options: [Auto] [0.500V] – [1.300V]
VTTDDR Voltage (CHC, CHD)
This item allows you to congure the termination voltage for memory channel C and
channel D. A setting of Auto scales this setting at 50% of the applied DRAM voltage.
Conguration options: [Auto] [0.500V] – [1.300V]
VPPDDR Voltage (CHA, CHB)
Auxiliary power supply to the DDR4 DRAM Modules on the left.
Conguration options: [Auto] [1.865V] – [3.135V]
VPPDDR Voltage (CHC, CHD)
Auxiliary power supply to the DDR4 DRAM Modules on the right.
Conguration options: [Auto] [1.865V] – [3.135V]
