Your VCore is dropping too low because of a potential issue with the UPS.
Your VCore is dropping too low because of a potential issue with the UPS.
You're checking the HWInfo readings after using UPS. Everything looks okay except for the motherboard VCore voltage, which is falling from 0.960 to around 0.300. That's unusual. The Ryzen 5 3600 with Core Boost disabled shows stable voltages in idle/desktop mode, but it drops during browsing or music playback. Is this typical behavior?
Unlikely to be correct—CPU voltage at idle wouldn't reach such a low level, and it would cause an immediate crash
It seems normal to check the readings; the processor shows stable core voltage, but the motherboard voltage fluctuates. No immediate concern unless patterns persist.
The PC is operating smoothly with no problems. After playing Watch Dogs 2, I noticed a slight drop in system info but everything remained stable. It seems normal that CPU readings are consistent while the motherboard stats fluctuate. I verified this using Ryzen Master and confirmed no significant drops.
HWiNFO offers sensor data handling independently, it doesn't directly pull information from the Motherboard BIOS. This means you might see varying readings across different programs, but HWiNFO is generally considered reliable. Ryzen Master comes from AMD, which might make it more precise. You could test an older HWiNFO version to check if the issue persists, or you might disregard it since it appears inconsistent. A UPS shouldn't impact vCore significantly, provided your PSU voltages (12V/5V/3.3V) are normal, then the rest of the voltages should be managed by the motherboard by converting 12V down to CPU levels as needed.
So everything is fine and there is no reason to worry ? I just decided to test it and when i leave it on desktop the Vcore drops to even lower 0.240 or something but when i open YouTube and start a video it goes back to 0.960-1.008V and it stays there only when its on Desktop drops that low and only the MOTHERBOARD Vcore
It seems you're not facing any problems, and 0.24V might actually be the correct idle voltage for your Ryzen. Low voltage doesn't harm the CPU.
