  1. JFYI if your CPU core and cache voltage offsets are different only the highest one will apply for the CPU package (except for AVX-512 instructions IIRC). So it makes no difference to set the CPU core offset to -200, -300 or -500mV if the CPU cache offset is set at -125mV, it will use the -125mV offset.

    Check if the battery slider is set to best performance, that sets the Speed Shift EPP to 0 which forces the CPU to work at full frequencies all the time. You can also try restoring the balanced profile settings.
  3. When a power throttling event happens it means that the CPU is consuming an amount of power higher than the power limit (and PL1 is, by default, the same as the TDP), after power throttling occurs the CPU is forced to work at a lower frequency so the consumed power doesn't exceed the limit, this is done to avoid overheating due to the system working at a higher power than the cooling system can dissipate. So power throttling is just proactive thermal throttling. Undervolting a CPU will allow it to work at a lower power therefore it won't surpass the power limit, of course if you undervolt the CPU too much it won't be able to get enough power under intensive tasks and you will get a BSOD (or a forced CPU shutdown if you set the undervolt really low). But in this case there are no signs of the CPU misbehaving due to a low voltage so he can undervolt it. TLDR: more voltage -> more power -> more heat so you want your voltage as low as possible
  4. There's not really a risk when you increase Icc Max value. The risk of increasing Power Max is higher temps on full load tasks. And btw -200mV is a very extreme undervolt and your system might be unstable.
  5. That's wrong, the power consumed will be much lower the lower your voltage is, so you're less likely to hit the power limits and your laptop will run cooler. I always recommend undervolting a laptop CPU since it's one of the best upgrades you can do to improve the performance of a laptop, start with -50mV (on both core and cache) and run prime95 for a few minutes and if everything is ok lower the voltage 10mV more, when you get a BSOD while running prime95 you'll know the limit of your chip so take that voltage offset and add 20mV to it just to be safe and you're good to go. If your laptop is still power throttling after undervolting just increase the turbo boost power max to match the short power max. And to get rid of the current throttling just increase the Icc Max value, it usually doesn't matter how high you set the limit so you can safely set it to unlimited if you want.
