The cores sound like they are having a hard time maintaining their frequency due to the clock (locking your state isn't overclocking, but it's pretty close to it). Your PState is running max while your BIOS thinks it should be giving non performance voltage.
Odds are you're going to have to up your voltage. It's not too dangerous, just don't red line it out the gate. Up it incrementally until you start to artifact/core dump. Then you know how high you can take it. The biggest thing is to NOT max your voltage on the first go. Up it a few .xx volts at a time.
For Example:
My Max NB/CPU vid Voltage is about 1.3 volts. Depending on temp, I may run to 1.31 (cold) or to 1.28 (hot). I don't exceed 1.31 EVER as I have core dumped and there was so much draw on my power supply that my computer stopped charging. I was lucky. If I blew a DC fuse, I would be getting a new computer.
