VDDP Voltage Control
VDDP is a voltage for the DDR4 bus signaling (PHY), and it is derived from your DRAM
Voltage (VDDIO_Mem). As a result, VDDP voltage in mV can approach but not exceed your
DRAM Voltage.
VDDP Voltage Control
Configuration options: [Auto] [Manual]
The following item appears only when VDDP Voltage Control is set to [Manual].
VDDP Voltage Control
Configuration options: [700] - [65535]
VDDG Voltage Control
VDDG represents voltage for the data portion of the Infinity Fabric. It is derived from the
CPU SoC/Uncore Voltage (VDD_SOC). VDDG can approach but not exceed VDD_SOC.

Onboard Voltage Controls
VDDIO Voltage Control
This item allows you to adjust MEM VDDIO, stepping is 4mV. VddIo = 1.2V +/- N
* 4 mV, input range is 0-31. Tuning range is +/- 120 mV. The Stepping is 13mV on
Turpan.
Configuration options: [Disabled] [Increase VDDIO] [Decrease VDDIO]
The following item appears only when VDDIO Voltage Control is set to [Increase VDDIO]
or [Decrease VDDIO].
Adjust MEM VDDIO Value
Configuration options: [0] - [31]
VTT Voltage Control
This item allows you to adjust VTT MEM, stepping is VDDIO * (1/256). VTT_MEM =
VDDIO * (N / 256), input eange is 113-143.
