If anyone interested here are my cinebench results from my 14700k overclocking. E cores havent been OCed at all for now only P cores. I have managed to get them all to 5.8ghz and 2 cores to 6ghz at 1.37v adaptive.
Mobo: Asrock Z790 PG riptide
RAM: 7200mhz DDR5 GSkill
AIO: Deepcool LT720
I set 500w and max i have seen was 337w at multicore benchmark
Did you try drop the vcore lower? 337W seems way to high for only minimal OC for P cores only
Yes i tried at stock. It was around 300-310w. This is very minor voltage increase probably around 0.015-20
Try to drop it to 1.3V then if worked try lower like 1.29 or 1.28.
