Download the AMD Chipset Drivers for Ryzen processors. This driver set offers optimized chipset compatibility with AMD Ryzen processors and AMD Socket AM4 - released August, 2019.
Ready for AMD Ryzen processors - AMD Socket AM4 represents the company’s new future-proof platform targeting the fastest DDR4 memory, PCIe 3.0, and NVMe technologies available, as well as the first native USB 3.1 Gen2 support on a chipset. With processor-direct SATA and USB connectivity, configurable for real-world flexibility, the new AM4 platform takes advantage of the leading-edge features of today and tomorrow.
Description:
This is an all-new chipset software installer with updated UI, optimized package size, package versioning unique to the chipset drivers, and improved installer performance.
Supports:
Windows® 7/10 for
- 2nd Gen AMD Ryzen Desktop Processor
- 7th-Gen AMD A-Series Processors
- AMD Ryzen Desktop Processor
- AMD X470 Chipset
- AMD X370 Chipset
- AMD B450 Chipset
- AMD B350 Chipset
- AMD A320 Chipset
Windows® 10 only for
- 3rd Gen AMD Ryzen Desktop Processor
- 2nd Gen AMD Ryzen Threadripper™ Processor
- AMD Ryzen Threadripper Processor
- AMD Ryzen Desktop Processor with Radeon Vega Graphics
- AMD Ryzen Mobile Processor with Radeon Vega Graphics
- AMD X399 Chipset
- AMD X570 Chipset
Package Includes:
- AMD Chipset Drivers
- AMD Ryzen™ Power Plans (required for UEFI CPPC2 in Windows® 10 May 2019 Update)
- Contains desktop idle optimizations for 3rd Gen AMD Ryzen™ Processors
- Resolves Destiny 2 game launch on 3rd Gen AMD Ryzen™ Processors
Windows OS automatically installs a generic driver that allows computers to recognize basic motherboard functions. However, to make use of all board components, appropriate chipset drivers must be applied.
If you install this package, the system will receive related information regarding the chipset. Also, this step might improve compatibility and bus transfer speeds, add various changes for sleep state behavior, power saving functionality and others, or include support for new features. To apply this release, simply make sure your system configuration is supported by this package, get the file, run the available setup, and follow the on-screen instructions. Bear in mind that installing inappropriate chipset drivers can cause computers to malfunction. In addition to that, do perform a system restart after you have completely applied the present release so that all changes take effect. Despite the off-chance that other OSes might be compatible, we do not recommend installing any software on platforms other than the highlighted ones.

but if i set minumum to 5 it downclocks to 2200 mhz when idle, if i set that 90, it practically doesn't downclock and stays always 3900, so is not good since i want to powersave when pc is idle
The minimum power/performance is read at OS boot, setting a lower value will not effect anything (eg: a CPU minimum power performance value is 40, you can set it at 5% or even 0% in the control panel of Windows, but it will not decrease under 40 so any lower values will be ignored). If you want avoid high CPU frequency spikes you can leave the minimum value at 90% like the Ryzen power plane.

Set it to 0 and your fine. I personally always switch to balanced for anything more than low load, so i dont even have it go past 2.2 by setting max cpu to 50( up to 61%) for power saving, balanced is 20/100%, so to not drop to low when i play games..

I'll say it one more time and then quit this topic:
What you see in Windows Task Manager or tools like CPU-z, CoreTemp, etc. while the CPU is in idle is NOT the real low clock of Ryzen !
(That includes Ryzen 1000, 2000 and also 3000).
The CPU clocks internally much lower than what is visible in all these tools, and is being controlled by the power management hardware inside the CPU itself !
Currently the only program that shows the real core clocks is Ryzen Master, and AMD keeps the inner workings of that tool as closed source, for whatever reason they want...
Setting the % of power management to anything lower than 99% only slows down the internal hardware mechanism to the software-level mechanism built into Windows.
Quick table:
100% - Downclocking completely disabled, minimum CPU frequency is the base frequency
99% - Hardware level downclocking enabled - CPU evaluates the load 1000 times per second and only gives it as much as needed to complete micro tasks (interrupt requests, audio buffer, network transfer, etc.). These rapid changes are not visible to the OS.
1-98% - Software level downclocking handled by Windows - The Windows Scheduler determines P-state only 60 times per second and sends it to the CPU, which must obey. This is slower to react than the 99% version. You will see the P-State clock in the tools ( from 2200 to whatever the base is )
0% - Core parking is Enabled, meaning CPU cores will flush their L1/L2 cache and completely stop when idle. Waking up from this takes a long time, which may induce stuttering in games and other real-time applications. It is the WORST possible thing to do on a desktop and is designed only for laptops or other battery-powered devices.
TL;DR:
When using a Ryzen CPU, DO NOT CHANGE from the 99% value ! It is NOT necessary to touch that.

Never said that, but please explain how it is better to use
99/100% with clocks between 3.6-4.2, when i can do the same things (idle/low power use like surfing/office/streaming/movies from drive)
with a 0/100 (balanced) or even 0/50 (on the power saving profile) with the cpu lowering clocks almost by half (2.2) and lowering voltage because of that, and reducing temps as well, without any noticeable impact on win?
Im getting more noticeable delay from my mouse waking up (logi doesnt allow measing with sleep modes anymore), than ive ever seen any negative from running fixed 2.2 ghz
