Hi. You're using an i7 8700 with a cooler that started overheating during Windows boot after a BIOS update from 0502 to 2301. It reaches temperatures near 100°C under stress or in games. The HWINFO shows a voltage of about 1.450V for the core VID, which seems too high for your BIOS/Windows settings. Rolling back isn't possible since Asus appears to have disabled that option. You've tried AFDOS fixes, but it works without errors yet keeps the same BIOS version. You're looking for ways to adjust or limit the voltage. A forum discussion mentioned a similar problem, but it didn't provide a solution.
Always bring your BIOS back to its original configuration after an update and reset everything to what you used to have. If you followed that process, could there be an issue? If not, it might be mixing up the previous settings.
I attempted to restore the default settings but didn’t see any changes. Consider resetting the CMOS chip if that might help.
I attempted to reset CMSO but it didn’t work. It matches exactly what you mentioned in your initial message, and I’m here to assist you further since this has happened before.
Experimented with various BIOS voltage configurations but still detected peaks up to 1.5V for VID in system info. Windows power mode is set to balanced. How can I restrict VID voltage? Update: Attempted to revert everything to defaults and turned off turbo boost in BIOS. The outcome showed a maximum VID of 1.15 and a peak of 67°C across cores during Cinebench R23 multicore test. Likely the turbo boost is causing excessive voltage spikes. How can I prevent that spike? Edited November 29, 2020 by chandre92 Added screenshot
Hey chandre92, I’ve got an Asus Prime H370-Plus, an I7 8700K, and a solid CPU cooler (Noctua NH-D14). I’ve been using BIOS 0802 for two years without any issues—quiet and cool. Last week I switched to BIOS 2501, and now my CPU runs about 20 degrees hotter under load, with noisy fans. I suspect the newer BIOS versions are causing the problem. I also saw your post on the Asus ROG Forum. Have you found a way to fix the overheating? Did you try BIOS 2701? Are you considering reverting to older BIOS versions?
