Turbo boost power wattage?

Hi all!
I've just got a new laptop for occasionally light gaming when not on deck/pc. Anyway as expected it thermal throttles.... alot
Reducing the short power max from 200w to 90w seems to reduce the processor performance from 4.5ghz to 4.2ghz approx, and stops the majority of throttling during stress so should be good for gaming.

My question is, how do I do this on throttlestop? Is the PL2 short the same thing? I really don't understand it I just followed a video with intle XTU to test but want to make throttle stop boot in task scheduler as i did with last laptop! I even undervolted from the bios a little (it's a 12650h so I wasn't expecting to be able to).

Any help and explanation would be great
Thank you

Do some Cinebench testing with and without a BIOS undervolt. Some H series CPUs have Intel Undervolt Protection enabled. When you try to undervolt in the BIOS, it will let you but you might end up with significantly reduced performance. Your Cinebench scores with and without an undervolt will show if an undervolt causes this problem. I have seen some 13600K processors on B760 boards with Cinebench scores cut in half because Undervolt Protection is enabled.

In the ThrottleStop TPL window, check the MMIO Lock box near the top right of this window. Clear the Disable Controls box and enter your power limits. What Intel XTU calls Turbo Boost Power Max is PL1 in ThrottleStop.

XTU Turbo Boost Short Power Max is PL2 in ThrottleStop.
 
Hi, thank you for your fast response!
So I have attached both with and without undervolt, both are very similar and I suspect within margin of error. I ran the test a few times and ofcourse the numbers were sightly different every time!
I can actually disable undervolt protection, maybe this is why it works?
I have this undervolt:
Processer offset -100
E core offset -50
Ring -50

Now throttlestop, I googled MMIO and it basically said that would disable the 2nd lot of power limits, apparently Intel set 2. Now in XTU the processor is saying 200w standard for both, but it's actually only a 115 or a 125w according to everywhere I looked, so xtu just lies about the original. So I set the short to 90w saving power, but unsure what to set the other to? Or would the same be good?
Thanks
