PLL (1P8) voltage - This option can be used to stabilize the CPU at high BCLKs. This is done by resistor parallel termination. So it's basically the voltage for the memory controller. VTT DDR voltage - voltage used to control the impedance of the bus in order to achieve the high speed and maintain signal integrity. A transistor switches from 1 and 0, this is how the computer does arithmetic and communicates, so what this voltage is doing is to stabilise the transistor that sets the content of a memory address. I'm not 100% sure if I'm correct, but if someone could correct me. Added reporting of basic SVID voltage regulator information and universal VR temperature. A cold reboot is required if you alter this voltage. Added reporting of cLDO VDDP and VDDG for AMD Zen2 family. Small changes to VDDP can have a big effect, and VDDP cannot not be set to a value greater than VDIMM - 0.1 V (not to exceed 1.05 V). AMD Quiet Cool PWM Phase Control CPU Vcore Loadline Calibration & Vcore SOC Loadline Calibration -> TURBO For this one, LLC setting in MSI's BIOS has 8 modes (mode 1 to 8). Advanced overclockers should also know that altering CLDO VDDP can move or resolve memory holes. By default, it is 0. Can only see VDDP voltage, VDDG CCD voltage, VDDG IOD voltage, DRAM voltage, DRAM VPP Voltage.

Somewhat counterintuitively, lowering VDDP can often be more beneficial for stability than raising CLDO_VDDP. The DDR4 PHY or physical-layer interface converts information from the memory controllers to a format the DDR4 memory modules can understand. VDDP voltage - voltage for the transistor that sets memory contents.ĬLDO VDDP voltage - voltage for the DDR4 PHY on the SoC.
