You're dealing with a tricky situation. It sounds like your CPU is overheating, which could be the main issue. The BIOS setting you adjusted to 1.3V might not be ideal since turbo mode keeps it above that threshold. Also, the high voltage reading and constant speed during rendering suggest thermal throttling or improper cooling. Check the temperature closely—if it stays above 80°C, the CPU will likely shut down. Consider using a better cooler or improving airflow.
Verify the power plan you've chosen in Windows. If it's set to "High Performance," the processor may run at full turbo clock, needing higher voltages and generating more heat. For Intel chips, adjust it to "Balanced" so the CPU throttles during idle tasks. Also review your BIOS for any power-saving options that might be off, and turn them on. The VID reported by Hwmonitor or similar tools reflects the voltage the CPU is requesting, not the actual supply voltage.
Check your settings for power mode options in Windows. You can usually adjust it through the power options or system settings menu. If you're having trouble locating it, try searching for "power settings" or "power plan" in the search bar.
i looked in the bios and saw only power mode enabled as auto. there was a choice between performance mode and max energy saving. i selected auto. in windows i set powerplan to auto, though it occasionally drops lower but usually stays around 4.3gHz with voltage between 1.3 to 1.42. edited december 21, 2019 by DiamondLight4
