Zenbook 3 Deluxe i5 8GB + Gaming Box RX580: Power Limit Throttling

Hej, as I've finally got some time on my hands to do some serious gaming, I am once again not happy with the performance of my setup:

Zenbook 3 Deluxe, i5-7200U, 8GB RAM + Gigabyte Gaming Box RX580

Whenever I'm playing games and the eGPU clocks starts rising, my CPU throttles very hard. From idling around 3.1 GHz, it throttles to as much as 1.2~1.4GHz. And even then the games don't fully utilize both the CPU and the eGPU.

I've tested this with games like Dota 2, Dark Souls 3 or Kerbal: nothing is running smoothly as the CPU seems to bottleneck very hard. Intel XTU is telling me, that "Power Limit Throttling" pushs it down to this low clockspeed. As the BIOS/UEFI seems to be locked pretty tightly I can't undervolt much higher than ~-0.085mV before getting BSODs. Any suggestions to make my christmas holidays much more jolly?
