Hello everyone, do you have any insights into this voltage variation on VPP (SWC) Voltage? I suspect it's not a hardware issue since the same voltage appears on two other DDR5 systems I've tested. It swings between 1.815 and 1.110V. The motherboard is an Asus TUF B650, the BIOS is the latest version, the RAM is Kingston Fury DDR5 at the default 4800MHz, and I'm using the default BIOS settings without EXPO or XMP enabled.

The issue shows up consistently across different kits. Some devices report incorrect voltages, like VDDQ showing 1.1V when it should be 1.35V, yet they still fail to boot. Similarly, VDD dropping from 1.45V to 1.15V doesn’t cause a blue screen, but the system remains unreliable. This pattern suggests a broader problem with voltage sensing in these units.
