+0.82V PCH Voltage
Allows you to configure the voltage for the +0.82V PCH.
+1.05 PCH Voltage
Allows you to configure the voltage for the +1.05 PCH.
DDR5 PMIC Configuration
PMIC Voltage Option
[United] Allows you to adjust DIMM PMIC altogether.
[Separate] Allows you to individually adjust DIMM PMIC.
VDD Voltage
Allows you to configure the VDD Voltage supported by PMIC at DRAM side. The VDD
output can be measured through PMIC ADC with step size 0.015V. VDD information is
contained in memory SPD and XMP, you can check it via Memory Information tool.
VDDQ Voltage
Allows you to configure the VDDQ Voltage supported by PMIC at DRAM side. The VDDQ
output can be measured through PMIC ADC with step size 0.015V. VDDQ information is
contained in memory SPD and XMP. You can check it via the Memory Information tool.
Configuration options: [JEDEC Standard] [OC Demand]
VDDQ Voltage Range
JEDEC Standard ranges from 0.800V to 1.435V. OC Demand ranges from 0.800V to 2.070V.
OC Demand may not be applied if PMIC OC CAP is JEDEC PMIC. You can check it via the
Memory Information tool.
Configuration options: [JEDEC Standard] [OC Demand]
VPP Voltage
Allows you to configure the VPP Voltage supported by PMIC at DRAM side. The VPP
output can be measured through PMIC ADC with step size 0.015V. VPP information is
contained in memory SPD and XMP. You can check it via the Memory Information tool.
FIVR Configuration
Ring Voltage Mode
Selects between adaptive and Override Voltage modes. In Override Mode the voltage
selected will be applied overall operating frequencies. In Adaptive Mode the voltage is
interpolated only in turbo mode.
