Post some screenshots of the FIVR and TPL windows. If CPU voltage control is not locked, I recommend going into the FIVR window and setting IccMax for both the core and the cache to the maximum value, 255.75. I also recommend setting Power Limit 4 in the TPL window to 0. This can help get rid of some types of EDP OTHER throttling.
Your screenshots show that at EPP = 0, the CPU is running slightly faster than when EPP = 128. Many CPUs can not achieve maximum performance when EPP = 128 so there is slightly less power consumption needed. TS shows 14.5W is bad and 10.1W is OK. EDP OTHER is usually caused by the current limit. Less power requires less current which results in less throttling.
Hopefully the suggestions above will help solve this throttling problem. A 10300H has a 45W TDP rating. Kind of silly for a manufacturer to use EDP OTHER throttling to keep it under 15W. That is just bad design.
