I see the way your voltage is fluctuating. I use a higher LLC setting. You may want to try. If your getting 1.440v at full load for stable, and idling at 1.464v. I set 1.450v bios and that's what it idles at, then under load it goes up to 1.472v.
There's no point to idle at a higher voltage. I see it better to idle at a lower voltage and when the chip goes into load, it then gets more volts. Instead of vise-versa. Just my
