Strange voltage readings
Strange voltage readings
Your voltage settings in the BIOS differ from the actual readings because the software reflects its own measurements, not the real core voltage. The Core Temp and VID values can vary based on the tools used and environmental factors. As for the Core Temp reading, it’s a general indicator but doesn’t necessarily mean your system is overheating—just be mindful of trends over time.
Regarding the core voltage being lower than expected, which is caused by vdroop—the natural decrease in voltage when the CPU requests it from idle—this issue typically appears as a noticeable drop when the processor transitions from idle to load. Adjusting the LLC setting from normal, high, Turbo, or Extreme (in the Gigabyte version) can help correct this. I currently set my LLC to Turbo to maintain a very flat voltage drop for my 4.9GHz vcore.
Regarding the lower core voltage compared to your setting, it's mainly due to vdroop, which is a natural reduction in voltage when the CPU requests power from idle. The more accurate explanation would be: Under normal conditions (if load-line calibration isn't enabled), you'll observe a notable decrease in CPU voltage when the processor transitions from idle to active mode. This voltage reduction can be fixed by adjusting the LLC configuration from standard, high, Turbo, and Extreme settings (the Gigabyte version). I've set my LLC to Turbo to maintain a stable 4.9GHz core voltage with minimal fluctuation.
The VID concern I encountered is also unclear, but another forum member clarified: Maximum VID represents the highest voltage permitted without overclocking. If your chip ever exceeds this limit under default BIOS settings and no software overclock is applied, the BIOS will halt the boot and signal a CPU error. You shouldn't worry about it.
The ability to exceed the max VID comes from applying overclocking adjustments. Max VID only applies when overclocking isn't active.
Sorry for the delayed reply (I missed my login details). The current core temp shows "VID" instead of "Max VID." I'm curious whether a high VID reading should worry me. I really don't want the chip running at 1.4v continuously.
I plan to check the LLC settings to address the droop and possibly increase the OC. However, I have a question: if the voltage drops safely to a stable level, is it still harmful for the CPU because it's adjusting the input voltage to compensate?
