AMD has released its latest Ryzen Chipset Software version 8.01.20.513 driver, which includes general bug fixes and performance improvements. These updates should provide Ryzen CPU owners with some quality-of-life enhancements. In the release highlights, AMD mentions that the installer file has been updated with a new installation wrapper called Install Shield. Interestingly, AMD notes that this latest package does not include the AMS Mailbox and S0i3 filter drivers, which now need to be installed independently on systems that require them or may produce errors without them. Finally, AMD acknowledges that some issues persist, such as the regression from branch version 7 to the earlier chipset driver branch version 6, but the company offers a workaround, which is listed below. We have included the entire changelog below, as well as a download option on TechPowerUp's download section page.

Hmmm... switching to Linux made things much easier in terms of driver upgrades. No need to install them separately. To quote a person I got to despise with time "it just works".

You do realize there are driver updates in Linux too, very often. And you need to recompile/update the kernel for many chipset/CPU related fixes and improvements. It's certainly not easier than Windows in that regard.

Anyway, updated these chipset drivers without issue. Win11/B850. Would be nice to see a changelog but oh well works great.

ehh? not a lot of people are compiling their own kernels unless you run gentoo or are testing something, a simple update command is gonna handle all of that in one go so he's right it is easier.

Ze chipset driver supports Windows 11 25H2 now.
It refused to install at first, claiming there was no AMD hardware - turned out it requires VBscript to be installed :/

I will be lurking for a bit to see how it goes before I bite the bullet.

I don't have any pending issues so hopefully will be totally smooth.

SteevoWhat are the bug fixes?
You have to go the extra mile, and download the release notes from the AMD website:

Just an example:
www.amd.com/en/support/downloads/drivers.html/chipsets/am4/x570.html (you dont have to choose X570, it can be any AM4 or AM5 chipset, as the whole thing is 1 universal package anyway, also the same for both W10 and W11)

--> under the chipset driver download:

Now what all these "bugfixes" mean in REALITY? No one on earth really knows.. unless someone working at AMD leaks the specifics. Which usually never happened in the past decade.

My question in exchange for these details:

This package doesn’t include AMS Mailbox driver and S0i3 filter driver support.

What are these AMS Mailbox, and S0i3 drivers, and what do they do in reality?

Also, I challenge anyone who knows what are all the rest for? I bet no one on Techpowerup readers know that.

I confirm, Windows is significantly more complex lol (not for us, I'm speaking in general)

***AMS Mailbox and S0i3 filter drivers***

I have a few questions!

1. Are people installing the two drivers separately?
2. Did the new chipset driver remove the old installation of those drivers?
3. If needed, where are folks downloading the drivers? I saw found an old ass AMD driver from Oct '25.

I installed the chipset drivers without issue yesterday and I don't see any issues with stability or glitches (its only been 12 hrs). Last thing I want to have is an unstable system in the middle of a World of Warcraft raid or M16+ dungeon...

I was hoping someone here knew! I did a quick search for both drivers and this article is the top result for both. There are a few straggling results from laptop OEMs that don't really explain what the drivers do, just address how to reinstall them on specific laptop models.

Guwapo772. Did the new chipset driver remove the old installation of those drivers?
Not that I've seen, I have to always use DriverStoreExplorer and manually remove the old versions else they just wastes disk space, but this isn't specific to just AMD.

AMS Mailbox and S0i3 are both AMD‑specific Windows drivers that handle low‑level communication and power‑management behavior on Ryzen systems.


AMS Mailbox driver

  • Purpose: “AMS Mailbox” is an ACPI device (ACPI\AMDI0090) with a driver called AMS‑MailBoxDrv that provides a communication channel (“mailbox”) between Windows software and firmware/management logic in the AMD platform.
  • What it actually does: It lets privileged AMD services and utilities send specific IOCTL (control) commands to the firmware for tasks like checking session type, handling AMD KVM/remote‑control features, and other platform‑management functions that normal drivers cannot access directly.
  • Impact if missing: The system will still boot and run, but some OEM/AMD tools or advanced platform features that rely on that mailbox interface may not work or may be limited.

S0i3 filter driver

  • Meaning of S0i3: “S0i3” refers to a very deep power‑saving idle sub‑state within the modern Windows “S0 low‑power idle” model (used especially on laptops) rather than a classic sleep state like S3.
  • Type of driver: It is a filter driver, i.e., a driver that sits on top of or below another driver stack to modify or extend how power‑state transitions are handled, without replacing the base driver itself.
  • What it actually does: The AMD S0i3 Filter Driver participates in controlling and validating transitions into and out of these deep S0i3 low‑power idle states on AMD platforms, helping the firmware and OS coordinate power gating, wake behavior, and device readiness.
  • Impact if missing: The machine will still operate, but it may not be able to use the deepest S0i3 idle state correctly, which can reduce battery life or change sleep/instant‑on behavior on supported systems.

Why the note in the release

When AMD’s chipset package says it “doesn’t include AMS Mailbox driver and S0i3 filter driver support,” it means those two optional, platform‑specific components are not bundled and must either be installed separately (often via OEM packages) or are simply not needed/used for your particular configuration.

Thanks for the AI-generated inflated blabbing. I rather appreciate a meat-answer here.

I am the first person to be annoyed by AI crap, but this actually sounds just like the information that was asked for. What is your problem?
