[SOLVED] AMD Cool n' Quiet feature not in BIOS

[SilentWolf445]

Hi,

I am new to PC building and had a few questions regarding my CPU, Ryzen 5 2600X. I noticed that it boosts to about 4.2 GHz on idle, which causes idle temps to be around 50 degrees Celsius. I did some research and found out that the Cool n' Quiet feature in the bios will prevent the cpu from boosting when in idle. However, my bios has no such setting (I have an Asus Strix B450-F motherboard). I downloaded the most recent chipset drivers as well and that option still is not in my bios. I enabled Global C-States control which apparently is another power saving option, but this causes my cpu to constantly jump between 2.2 GHz and 4.2. Do I need to download some sort of special driver to enable the Cool n' Quiet feature?
I also have another issue. I do not have the AMD Ryzen Power Plan listed under my power options, even though I download the most recent motherboard chipset driver. I am currently on the Windows Balanced Power plan.
Does anyone know what the issue could be or is Cool n' Quiet not supported by my motherboard? If you know a solution, a step by step guide would be helpful as this is my first PC build.
Thank you.

It's not called Cool n' Quiet any more (except on some Gigabyte MBs), C-states replaced it. Frequency is going to constantly jump up and down in response to demands from OS and programs, no escape from that. That's what it's for, to keep frequency down until needed. Cool n' Quiet would just slow it down even if it existed. Only way would be to set frequency manually to a preset value.

I wonder...

on my board, a b450 mortar, i have both a C-States selector and a CnQ. But perversely, if i set CnQ to enabled then 'boosting' essentially stops for my 3700X, it instead peaks at about 3775 or 3800 and that's it. I have to set it to disabled and I've always kept C-States enabled, never tested that one disabled.

Most people say you have to have CnQ enabled to get boosting under PBO, but mine's been the opposite with that too. I have to have it disabled. Again, I've always left C-States enabled so maybe I should test that just to see.

I'm really not sure what's happening and maybe my BIOS is just a bit messed up in that area... could it be because I have both a C-States and CnQ toggle?
