The .68 drivers are available here: https://yadi.sk/d/elVdi3YjM6M-7A and are hosted by and have the same password as Canonkong’s other drivers which are why I originally believed them to be his.

Thank you very much for posting link for the "X570_149C_Drivers_B2". This is the only version that works for me with the Ryzen 5 3600 + Asus TUF X470-Plus Gaming (on W7-64).
Version "Ryzen 3000_4000_Serise_149C_Drivers_B4_Win7_8.1_SHA256" did not work for me (error, not for your platform) and overwriting inf in AMD drivers also did not work (crash, second part of drivers could not be installed).
Thank you once again!

With great appreciation I'm running "3000_4000_Serise_149C_Drivers_B4_Win7_8.1_SHA256.7z" with my system in my Profile. I used the Chipset from the DVD included, from there I was using B2, but that caused some problems. BSOD, and so on. I am using an SSD that had Windows 7U 64-Bit installed from my previous machine from 10 years ago. (2 Core).. I cleaned all drivers from older machine (Device Manager) and at times it was tricky to get B2 installed and removed..though when working is did well, but didn't "wake" from "sleep".

B4 is a big improvement. All USB 3.2 speeds seem to be active even though I'm using older SSD and 3.x connections with fast Hard Drives.. The USB mouse and Keyboard "wake" from power button press, but Not from Keyboard Shift Key. If I press Shift they Keyboard lights shine, and let go..off. Press...shine. Let go, off. Then press power, they'll light as normal, but then I have to use PS/2 mouse to reset machine.

If I start "Sleep Mode" and then press Power button, the Windows 7 screen shows, USB Mouse is active..USB Keyboard is lit, and mouse allows to click on account. From there sometimes a slight "glitch" with movement, but mouse remains totally usable. Desktop, Games, programs..so on.

Only problem I've noticed so far is...as you can tell, "Sleep Mode". I haven't checked Hibernation as I rarely use that. I'm currently testing these more. So far, really, really glad to "have" Windows 7 working well! Any questions? I'll do what I may to help.

When installing Win7 on AsRock B550M Pro4, the blue screen appears during bootup. T.T

Becaus AMD have some bug about ZEN2 CPU on X570/B550 mainboard with the new v2 AGESA. Only ZEN/ZEN+ CPU/APU and Zen2 APU can work fine. So wait for the new bios.

My msi A-pro also doesn't work well:
There are some devices I suspect need a very stable connection which fail most of the time. one for example is a R/C simulator controller which is also coded for software authentication evaluation. this one now fails all the time.
works perfectly in win 10
Second is an ftdi connected type of controller which also now fails to connect.

Hello everyone.

I think that in this thread it must be included the motherboards (of course mobos with CSM, unless there are other workarounds for this problem too) that have been successfully worked with ryzen 3950x (so far the top chip that AM4 can accept) and WIN7 with the modded drivers. I am planning more than a year to build a ryzen system but I have stuck with the motherboard sellection. I want to go in the details (that might be important for other ppl that want to build ryzen systems close to my build) but I might highjack this thread. Please let me know for posting further details. I want to build my system YESTERDAY and use nothing else but WIN7. I post here because I saw that b550 motherboars might work with modded drivers and WIN7

@Johannes Krauser If you want, you can use the same motherboard like me.

@Johannes Krauser read this post.
Windows XP 32-Bit and Server 2003 32-Bit on Modern Hardware (338)
[Solution] Win7/8.1 Drivers for USB 3.0/3.1 Controllers of new AMD Chipset Systems (15)

windows7 won't boot on the combination of 3950x and AGESA Combo V2 1.0.0.2(V2 1.0.0.1).

So how to deal with this bug? It's unlikely that amd "fixes" this issue..
https://community.amd.com/thread/254499

Bump.. Does latest AGESA verisons fixed the problem? Can anyone confirm? Also is it possible to downgrade AGESA?

@Johannes Krauser
MSI 5XX already fix this problem with the testing bios. Just wait for few weeks，maybe others will fellow.

Hi folks, recently got a Ryzen 3900X and an Asus TUF X570 to replace my old hardware. I'm trying to get Win 7 installed on an Intel Series 6 NVMe drive, however I'm struggling quite a bit. When I boot into Windows 7 setup, I'm unable to access any USB ports, including USB 2.0 ports connected to the motherboard header. I have a PS/2 keyboard so I didn't think this would be a big deal, except I can't access drivers via USB and thus can't get setup to proceed using a USB stick. I figured out a workaround by using another HDD with the drivers on them, but whenever I try to load the USB drivers i get BSOD with STOP 1 (I read earlier in this thread that I need to install the chipset drivers first, but I can't figure out how to do this). I tried to use a DVD instead and got to the point of selecting a hard drive, but the NVMe drive is not there and when I look for drivers in Canonkong's folder, it doesn't find anything. Do I need the Intel RST drivers instead? Would appreciate some help I'm up to my eyeballs in this stuff

Try these Windows 7 X470 chipset drivers for your X570 board, as a number of the chipsets are the same:
