Just setting PL2 in the BIOS doesn’t help much since the CPU and motherboard will still use high voltages for no reason. Best method is setting PL2 at 241w and reducing the voltage via V/F and you’ll get same performance at around 170w CPU package in Cinebench. 27k multi points at 170w is efficient as hell.
Motherboards sometimes actually already use lower CPU voltages than they should, to the point of instability during certain loads at high power levels. My Gigabyte Aorus B560M was one such cases. At normal or even moderately intense loads it was stable, but it quickly failed with intense benchmarks like Prime95 or Linpack, giving calculation errors, all at stock/default settings. The motherboard is fine; default settings were bad.
So, while you may find your voltage too high for typical loads, care must be taken to make sure that by lowering it stability is still maintained at all loads and also temperatures, at least if you value that.
