@AnxiousBeat Your undervolt is too much. Do not undervolt the Intel GPU. Set that to +0.0000. Try setting only the core and the cache to an offset of -60 mV. If this is stable for a few days, try a little more. Most of these CPUs lose stability if you go beyond -75 mV. When you lower the turbo ratios and run the CPU slower than its default speed, you usually have to reduce the amount of your undervolt.
Reduce the undervolt as much as necessary until the blue screens completely go away.
