Power limit 8600k for home server porpose

[Vy-Ro]

Hi, as per title my question is, how do i power limit a 8600k or any 8th gen intel cpu? I couldnt find anything online about, maybe my wording is wrong but i kinda undestand, you wouldn't usuall power limit a k cpu. I have it laying around and i intend to use it to replace the 3770 that is have in my home server (jellyfin/nas/file sharing),it run open media vault. I was looking for an 8400t but hey i already have this. I;m asking this because i'm used to the amd way where you can limit the power a cpu can draw but i don't know if i can do the ssame on an intel cpu. Any chance someone knows?

Look for power limit in bios. It is split into short term power limit and long term power limit, so that the CPU can boost harder for short times. If you don't want that, you can set both to the same power limit. Not all bios exposes this. If that is the case, you can try turning off turbo which in effect limits the CPU to its TDP. Alternatively you could look at software tools to do this, like XTU.

Power limiting your CPU is not going to limit its power draw at idle. Also, the 8600K isn't a CPU that draws a lot of power under full load. My 9700 never went above 130W unless I tried and in games it would max out at 110W. Your 8600K is likely gonna stay below 65W most of the time and will draw less than 10W at idle

What motherboard are you using?

Likely, disabling (it's usually Enabled by default) Multi-Core Enhancement (MCE) should keep the CPU power within Intel rated spec.

You can use ThrottleStop to set the power limits of any Intel Core i CPU as long as the BIOS has not locked out this setting. ThrottleStop gives you  access to the Clamp options. This can force the CPU to run under its base frequency when necessary so power consumption does not exceed the power limit values you have requested. The BIOS of most motherboards do not give you access to the Clamp options. 

 

The 10850K has a 125W TDP rating. Here is an example with both power limits set to 65W. The CPU can still run at full speed when lightly loaded as long as power consumption is under 65W. 

 

 

Enable the C states in the BIOS if you want to minimize light load power consumption. Idle cores that spend 99% of their time in the low power C7 state saves power.

I'm gonna bet this is gonna be locked

It's an OC board. The setting will be in the bios somewhere. I had the lower end Pro4 of that generation and that had it.

Looks like i did it, even at 99% the casa os dash says 35 or so watt (i set it like that), i know software report is not to be trusted , but i will try with a powermeter from the  wall, thank you everyone
