Does voltage exceed the Vcore setting in Bios after intense gaming sessions?
Does voltage exceed the Vcore setting in Bios after intense gaming sessions?
Hello, in recent weeks I've been pushing my CPU, GPU, and RAM to their limits, achieving solid performance boosts while keeping temperatures below 70°C during heavy workloads. However, I have a worry about the VCore/VID values in the BIOS, which are rising noticeably after long gaming marathons with AAA titles. After researching various helpful guides, I tried different voltage configurations and settled on an adaptive offset of -1 at 1.295V, using the lowest Vdroop/LLC setting at 25%. This setup worked better than the previous 50% configuration, which caused even larger spikes. I also switched my power plan to balanced and set GPU power to adaptive. Attached are some images for reference.
During gameplay, everything runs smoothly according to the HW monitor—VID stays within VCore. But once I enter BIOS after a solid gaming session (about 4 to 5 hours), the VCore or VID can jump significantly, sometimes reaching as high as 1.464V. It’s worth noting that after a few hours of gaming, the values return to normal, but they gradually increase again in BIOS. I’ve included photos of my overclocked BIOS settings for your understanding.
Regarding my PC specifications:
- MSI X99A Raider
- Click 5 latest BIOS
- Windows 10 64-bit, I76800K OC to 4.2MHz
- NVIDIA RTX2070 OC up to 2025MHz/Mem 8088MHz
- DDR4 3X8GB OC-3000MHz
- Corsair H55 Liquid Cooling
- Corsair 750W CX750 PSU
Should I be concerned about these rapid spikes? Is there anything I can adjust to prevent them?
For reference, here are the BIOS settings and screenshots:

Thank you for your support and advice.
After trying various adjustments, I seem to have resolved the issue myself and will post my solution. I raised the offset to -0.004 in BIOS for voltage, reduced core voltage to +90 and power limit to 100 in MSI Afterburner. It's great that I no longer experience large voltage spikes.
