DRAM Voltage
Allows you to configure the DRAM Voltage for CPU I/O to memory.
VDD_CPU Voltage
Allows you to configure the VDD_CPU Voltage for CPU I/O to memory.
VDD_IMC Voltage
Allows you to configure the VDD_IMC Voltage for CPU memory controller.
+1.8V PROC Voltage
Allows you to configure the voltage for the +1.8V PROC.
+1.05V PROC Voltage
Allows you to configure the voltage for the +1.05V PROC.
VCCIN AUX Voltage
Allows you to configure the voltage for the VCCIN AUX.
+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.
VDD 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]
