Voltage too high compared to BIOS settings
Voltage too high compared to BIOS settings
You're seeing normal behavior with your overclocked CPU. BIOS and HWinfo64 readings can differ due to calibration or power delivery quirks. At 1.45v, it's within the safe range for 24/7 use, especially since you mentioned it's compatible with DDR4 up to 1.5v. No major concerns here.
It depends on the specific DDR4 modules; usually they work fine as long as you keep them cool. They handle overclocking well. The screenshots mention some unfamiliar terms from MSI Bios, so maybe you can adjust the auto memory voltage manually.
