    Undervolting doesn't get rid of Power Limit Throttling, IMHO.

    It improves maximum sustainable speeds during extended stress periods, even if the CPU overheats.

    PL throttle can be solved with lowering temps, since silicon likes low temp and is more power efficient that way. Though the effects on laptops that can only drop a few degrees after repaste is questionable.

    I have already repasted and have seen a significant drop in temperatures; also got rid of thermal throttling.
    But now this PL throttling has come up which wasn't there before.

    You were likely thermal throttling before and now you are running into power limitations. It's common, at least you're getting more speed out of it. An undervolted CPU uses less power and will run faster before it PL throttles. You may be able to change your power limits with Throttle Stop but you'll likely hit the thermal barrier again.

    You can use throttlestop to set TDP UP (level 1), try it out.

    Couldn't get you brother....Can't I use XTU for adjusting TDP?
