Conguration options: [Auto] [Ultra Fast] [Fast] [Normal] [Slow]
PCIE/DMI Slew Rate
This item allows you to set the speed at which each clock rises and falls.
Conguration options: [Auto] [1.5V/ns] [2.5V/ns] [3.5V/ns] [4.5V/ns]
VTTDDR Voltage(CHC, CHD)
This item allows you to congure the termination voltage for memory channel C and
channel D. Setting is at Auto, scales this setting at 50% of the applied DRAM voltage.
Use the <+> or <-> to adjust the value. The values have an interval of 0.00625V.
Conguration options: [Auto] [0.500] - [1.300]
VPPDDR Voltage(CHC, CHD)
This item allows you to congure the auxiliary power supply to the DDR4 DRAM
Modules on the right. Use the <+> or <-> to adjust the value. The values have an
interval of 0.005V.
