Best way to Limit i9-9900K?

[Shonk]

I have spent the last few days getting my new setup stable

Which at 4.7Ghz all core results in a max load of around 175w with Prime 95 Small FFT
which lets face it is a worse case scenario my cooler is capable of dissipating this so its fine

Now to get it stable at 5Ghz all core i had to bump the Dynamic Vcore(DVID) +0.025V

This results in a worst case load of over 220W with Prime 95 Small FFT at 5Ghz
My cooler is is only able to manage 180W of sustained load

the way i see it i have 2 ways to ensure it doesnt get out of control


Set either of the following

A) Set Package Power Limit1 - TDP (Watts) to 180W with it kicking in after 1 second unconstrained
or
B) Set TjMAX Temperature 92° and let my worst 2 cores bounce on the 92 limit results in a load of 181.8W

Does anyone know which is the best way from a performance perspective

oh and btw if i let it bounce off the 100° TjMAX results in a load of 200W

For real life workloads temps wont get anywhere near as bad as this but
i want to enforce some sort of limit anyway

My Bios Settings

Same for 4.7ghz but no offset and no TjMAX limit

A custom power plan for Windows maybe? Limit the CPU to 90% or less should cap/peg the voltage?

Depending on what you’re doing you could also temporarily disable HT and make your 9900k a 9700k.

Well that's the thing, real life and TDP ratings don't have much correlation. Unless you're running sustained 100% loads over all logical cores or your favourite game isn't Prime95, just keep an eye on it and try not to worry too much. The CPU will be boosting and bouncing off all its internal metrics when needed. 180w dissipation on the cooler isn't to be sniffed at.

Imo of course

If you're going to limit a 9900k.....














Should've got a 3700x instead.
