unlocking cpu power limit

not 100% sure about this one so im asking here:

if ill remove the cpu power limit can it technically damage the cpu?

im not 100% sure

the voltage wont be changed only the power limit so the cpu could draw more power

from my motherboard's manual:

--

Turbo Power Limits
Allows you to set a power limit for CPU Turbo mode. When the CPU power consumption exceeds the
specified power limit, the CPU will automatically reduce the core frequency in order to reduce the power.
Auto sets the power limit according to the CPU specifications. (Default: Auto)

--

Package Power Limit TDP (Watts) / Package Power Limit Time
Allows you to set the power limit for CPU Turbomode and how long it takes to operate at the specified power
limit. If the specified value is exceeded, the CPU will automatically reduce the core frequency in order to
reduce the power. Auto sets the power limit according to the CPU specifications. This item is configurable
only when Turbo Power Limits is set to Enabled. (Default: Auto)

Not the CPU, but maybe the board if it's not designed to handle more power draw

If I understand correctly the setting will cause the cpu to ignore Intels boost time limits, causing it to maintain higher boost clocks longer or indefinitely.
Primary concerns are mobo power delivery and cpu cooling.

What CPU do you have? It’s not going to draw more power unless it’s overclocked and actually exceeding the amperage that is “allowed” by the bios. 
 

Power is a function of voltage and amperage, so if you don’t change the voltage only way for it to draw more is via it pulling more amps. All of that said, it’s likely not hitting power limits.

Correct, on current gen intel I believe this is correct.

i went with a gigabyte z490 vision g which is a mad overkill for my 10600K but im planning on upgrading to a 10900K or the next gen 11900K in 3 or 4 years so i choose to go all out on a reasonably motherboard now - it will be able to handle a fully overclocked 10900K at 5.1GHZ and above

for cooling i have corsair's H100X 240MM aio

got a 10600K

already overclocked it to 4.8GHZ at 1.29V 

4.9GHZ is unstable at 1.32 and 1.33 and i dont want to give it a lot of voltage and 5GHZ BSODs on startup

i know that maybe the silicon is not 'da best' best i wonder if removing the power limits will help

on siliconlottery.com they tested the 10600K on 5GHZ and its power limit is set to 180w

You can up the limit, it’ll only pull what it wants to pull. I doubt it will help but worth a shot I suppose.
