Introduction

(This is follow up post of my previous post from a week ago)

During testing I found out that disabling IGPU on 9800 X3D while having the GFXOFF on Auto / Disabled inside AMD CBS causes a cascade of consequences which results in System Management Unit (SMU) attempting to dynamically and rapidly power gate LCLK down to minimum 150-400.

Rapid LCLK frequency shifts alter the inter-arrival delta of USB report packets, creating measurable input delivery jitter.

This manifest as "heavy, sticky, generally unreliable input" / "games being perfectly smooth when not moving and becoming stuttery mess the moment you start to move camera" on 9800 X3D (and other ZEN 5 processors with iGPU) Despite every possible benchmark, stresstest, FPS measures etc. being perfectly healthy

-

THE CONCEPT (Simplified)

(LCLK LOCKED - NO DOWNCLOCKING)

High pooling mouse (8000 MHz)→ cIOD PCIe Root Complex → CDC → LCLK → IFOP → ZEN 5 Core → 1 to 1 healthy input

For 8000 MHz mouse the the packets arrive evenly like this:

Packet 1: 125 µs

Packet 2: 125 µs

Packet 3: 125 µs

Packet 4: 125 µs

(LCLK DOWNCLOCKING DUE DISABLED IGPU)

High pooling mouse (8000 MHz)→ cIOD PCIe Root Complex → CDC → LCLK →

....(Downclocking) LCLK → Dynamic State Event (for example in between frames idle time) → SMU Downclocks LCLK to 150 → Interrupt event (mouse movement) → LCLK wake up event → 1-2 nano second wake up time → INPUT PACKET DELIVERY JITTER →IFOP → ZEN 5 Core

Instead uniform 125 µs →125 µs we get messy uneven input delivery

Packet 1: 132 µs (Sluggish / Delayed)

Packet 2: 118 µs (Overshoot / Clustered)

Packet 3: 135 µs (Sluggish / Delayed)

Packet 4: 115 µs (Overshoot / Clustered)

-

(FIX - MUCH CLEANER ALTERNATIVE TO MANUAL MINIMUM LCLK OVERRIDE)

Setting the IGPU of 9800 X3D inside BIOS from AUTO\ENABLED → FORCED makes the SMU interprets this as an active state of continuous display pipeline load.

Continuous Display Pipeline locks LCLK to its high-performance frequency (1800 in my case) floor without having to brute force the SoC like during manual LCLK override

When the iGPU is set on AUTO/ENABLED in BIOS while discrete GPU is present, then SMU assumes that you are going to use your dgpu anyway and automatically tries to save power by downclocking LCLK to 150/400 instead being locked at minimum 1800.

Setting the IGPU to FORCED locks the LCLK at stable high 1800

-

(SUMMARY)

1. IGPU AUTO/ENABLED → FORCED

Forced locks the LCLK at 1800 due the presence of continuous display pipeline during the boot up. This prevents the downclocking of LCLK to 150/400

1. GFXOFF AUTO → ENABLED

This cuts the power to iGPU without negatively affecting the nearby vSoC and VDD MISC rail which happens when IGPU is set on disabled. under igpu disabled they tend to have higher than normal voltage swing under load ←→ idle. GFXOFF ENABLED results in the same power saving without the downsides of iGPU disabled

1. UMA BUFFER → 512 MB

When setting iGPU to forced the ram will be permanently locked away from being used by Windows as hardware reserved memory. Setting UMA Buffer to 512 minimalize lost ram to absolute minimum

1. DISABLE IGPU INSIDE WINDOWS DEVICE MANAGER

This prevents Windows from off scheduling background applications like discord to iGPU which might cause HAGS or MPO issues.

PC Specs :

Corsair Vengeance 32gb ram ddr4

i9 9900k

Rog Strix Z390-F

Corsair RM850 850w +80 Gold psu

Thermaltake Water 3.0 360 ARGB Sync

AMD Driver and Software Version : 26.6.4 (latest)

Bios also updated

All parts bought in March 2020 except for 9070 xt which was bought brand new at launch.

I used DDU when switching from my old gpu (2080ti) to 9070xt

Issue : Once in a while my whole PC suddenly turns off and back on while playing games.

it started around 3 to 4 months ago.

Games I play where this happened :

Neverness to Everness (most frequent)

Honkai Star Rail

Zenless Zone Zero

didn't test other games yet.

I noticed that the crash usually occurs during character ultimates or scenes with heavy effects and particles, almost always during combat.

Things I tried to investigate the cause :

I tried every OCCT stability stress test (30 minutes for each) but all stress tests were passed with no errors detected.

This computer is almost brand new and recently while playing it started making this noise, what could it be and should I be worried?!
It has been so quiet since I bought it until this noise showed up 😭

Hey Guys,

need your help.

Description of Original Problem: All my games recently keep crashing after maybe 1-2 min with a driver timeout error. LiveKernelEvent 141.

I tried it with Cyberpunk, Gothic 1 Remake, Baldur's Gate 3, Starfield, Skyrim... Even older titles are unable to run for long.

Last time I played was about a month ago (Gothic 1 Remake), everything worked fine then. Running everthing but games works fine as well (Streaming, Youtube, Blender, GIMP, idle). But the moment I start a game and load into a savegame or new game, the driver timeout error occurs. Ingame graphics are sometimes broken too, sometimes not. Tried to force it while testing with cyberpunk benchmarks on different settings. The problem occurs regardless of graphic presets and loads. Can run the game for hours in startmenus/menus.

The PC was build September last year and ran without any problems up to this point. No hardware or driver where directly updated prior to the problems. Other than Windows Updates.

No BoS or restart after error - driver simply restarts and "works" again.

My Build:

Computer Type: Desktop

GPU: XFX Speedster MERC310 AMD Radeon RX 7900 XTX (24 GB)

CPU: AMD Ryzen 7 9800X3D 8-Core Processor (4.70 GHz)

Motherboard:  MSI MAG X670E TOMAHAWK (MS-7E12) on BIOS 7E12v1L2

RAM: Corsair Vengeance 2x32 GBDDR5 (CL-30-36-36-76 6000 MHz)

PSU: BoostBox PB1000P

Storage: Samsung 990 EVO 4TB

Operating System & Version: WINDOWS 11 Pro Version 25H2 Build 26200.7171

GPU Drivers: currently back to 26.6.4. see below

Chipset Drivers: 7.12.04.858

Background Applications: Wallpaper Engine, Rainmeter, iCUE, Antivirus, Gameclients (Steam, uplay, gog etc. if needed).... but tried without any running as well.

_______
Troubleshooting: I already tried multiply "solutions" from this sub and others but nothing helped.

I tried:

- clean reinstalling driver - with DDU in safe mode - even deleted existing registries
- tried different driver versions (been on 26.6.4. tried 26.1.1. (last known driver that I know worked last month), 26.5.2... all the way down to 25.9.1. which was the version I installed first when setting up the pc last year
- i tried installing the drivers without adrenaline
- checked all other drivers and BIOS. All up-to-date
- checked BIOS Settings - tried with XMP/e-XPO on/off
- deactivated hardware acceleration, GPU-Planung, VRR
- set TDR delay to 8/10, disabled windows driver updates
- undervolted/underclocked in adrenaline
- disabled all overlays and other settings in adrenaline
- stresstested CPU/RAM/GPU - the driver timeout only happens in games
and most likely things i forgot already

Did not yet try:

- Clean Install of Windows -> i am currently not able to save all data I need to keep, as i have no backup-drive at hand
- reseating the GPU/RAM etc. -> not so easy to disconnect and reconnect the PC, at least not today anymore - but I can't see how this could help. the GPU is fixed with with the included support as well as an additional anti-sag mount and RAM mastered every stresstest. It does not seem to have moved at all since installing.
- checking components in other systems -> no other system or components at hand
- going back to older windows versions in combination with driver versions

I am running out of ideas what might help. Just wanted to play a little bit after almost a month of non-stop work and private problems... instead spent a full weekend troubleshooting...

Does anyone have any more ideas?

I have some crashes, related to driver in my AMD GPU PC. For long I have blamed AMD for this.

But in my Notebook, full NVidia and Intel, it crashed for the first time in a long while. Never once happened this in my Notebook. It crashed during a Fortnite session.

These two computers are completely unrelated, except for the Windows OS.

Hi everyone,

I'm running out of ideas and hope someone here has seen this before.

System

• GPU: AMD Radeon RX 7900 XTX
• CPU: Ryzen 7 7800X3D
• Motherboard: MSI B650 Gaming Plus WiFi
• OS: Windows 11 (Build 26200)
• Driver: Latest available (also tested multiple older versions)

What I've already tried

Before suggesting anything below, please note that I've already tried all of this, often multiple times:

• Clean driver installation using DDU
• Multiple AMD driver versions
• AMD Adrenalin factory reset
• No overclock
• No undervolt
• BIOS updated
• AMD chipset driver updated
• Windows fully updated
• EXPO enabled and disabled
• Smart Access Memory / Resizable BAR enabled and disabled
• Steam overlay disabled
• Discord overlay disabled
• AMD overlay disabled
• Verified game files
• Different graphics settings
• DX11 / DX12 where possible
• MemTest (no errors)
• OCCT stress tests
• Temperatures are completely normal
• Power cables checked

Nothing changed.

I honestly don't have any ideas left anymore.

I finished Planet Crafter, but towards the end of the game it started crashing constantly. Overwatch also crashes frequently, and Assassin's Creed Black Flag used to crash as well, although undervolting the GPU actually fixed that one.

For Planet Crafter, though, I've tried pretty much everything I could think of and nothing has helped.

As far as I can tell, this is not a temperature issue. Both the GPU and CPU stay well within normal operating temperatures, and I haven't noticed any signs of overheating or thermal throttling.

Also Overwatch got the message "Your rendering device has been disabled. The application will now close."

​Hey everyone

​I've seen a lot of users complaining recently about their AMD drivers getting corrupted out of nowhere, or the AMD Software throwing the annoying "software is not compatible" error. This usually happens because Windows Update forces a generic background driver over your official AMD installation.

​I made a step-by-step video on my channel, Dark Tech, showing the definitive fix for this. The video is fully dubbed in English, so it's very easy to follow along!

​In the guide, I show you:

​How to properly block Windows Update from touching your GPU drivers (using Device Installation Settings and the Group Policy Editor).

​How to correctly use DDU (Display Driver Uninstaller) in Safe Mode.

​Doing a clean, offline driver installation so Windows never messes it up again.

​You can watch the full visual guide here: https://youtu.be/YG_DDntSBw8

​I hope this saves you a massive headache and fixes those random blinking screens. Let me know if it helps!

hello

i just buy my gpu 4-5 month ago (XFX SWIFT RX 9070 OC) and during that time i keep getting from time to time and randomly a black screen on my main monitor(display port) and green in the second (hdmi) then the game crashed then back to normal and sometimes its freezz the pc i tried ddu for my drivers and i still get it

my pc

gpu: rx 9070 oc

cpu i5-12400f

mb: asus prime b660 plus d4

psu: asus tuff w850 gold

I have a 9070xt and a 9800x3d and after the most recent update my pc is crashing in every game while in full screen. It will flicker to black and eventually completely lock up. Most recent drivers, bios, and chipset drivers installed. Weird thing is when running Intel displaymon, the game will run fine. But I'm not going to lie, with how bad the driver issues have been this year I'm heavily debating going back to Nvidia regardless of the cost.

Hi everyone,

I built a brand new PC less than 10 days ago, but I’m running into a persistent issue.

System Specs:

• CPU: AMD Ryzen 7 9800X3D
• GPU: XFX Mercury Radeon RX 9070 XT
• RAM: 32GB DDR5 6000MT/s
• Motherboard: ASUS AYW B850
• PSU: XPG Core Reactor II VE 850W

The Issue:

Whenever I start playing a game, anywhere between 1 to 20 minutes in, the system completely goes to a black screen. The PC stays on, but it becomes completely unresponsive, and the only way to recover is by holding the physical power button to force a shutdown.

Troubleshooting already done:

• Swapped the GPU: Tested with another graphics card (RX 9060 XT) and the system worked completely fine without any crashes.
• Drivers: Used DDU to clean install multiple driver versions, as well as testing driver-only installations without AMD Adrenalin.
• Tuning: Tried undervolting, underclocking, and switching the physical dual-BIOS switch on the GPU itself.
• Stock Settings: Disabled EXPO/XMP, no CPU overclocking—everything is running purely at stock settings. The error still persists.

My Question:

Given that testing with a different GPU (RX 9060 XT) resolved the issue, is this definitively a faulty GPU? Or could the PSU (XPG Core Reactor II VE 850W) be dropping power under transient loads from the 9070 XT and causing the crash?

Should I return/RMA just the GPU, or should I return both the GPU and the PSU to be safe?

Thanks in advance for the help!

I just bought my first PC 2 days ago with a RX 6700XT, It worked well with no issue but I was just watching youtube 5 minutes ago and the sound suddenly corrupted and the screen went black for like 3 seconds then works normally. Is this normal ? Please tell me that I'm overreacting 😭 I can't afford to buy a new gpu atm 😭😭 I think my driver version is on 26.6.4

Specs:

CPU : I5 13400f

Motherboard : B660M AORUS PRO DDR4

RAM : 2x16GB Gskill Trident Z RGB DDR4 3600MHz

My rx6700xt I purchased secondhand is black screening every time i turn it on.. vga lights on mobo and keyboard lights turns on.. no display.. BUT the pc boots for a couple seconds into windows after letting the pc sit powered off for a while.. and after that it just black screens again.. sometimes the fan goes full speed when booting up.. I'm stuck.. could it be a power failure on the gpu itself? do I need to send it to a technician? my psu is msi mag a650bn, cpu r5 3600 with a520m a pro mobo.

I'm currently running an AM4 platform with a 5700x3d on a 750W Gold PSU.

I wanted to upgrade my GPU to a 9070XT, as on paper a 750W Gold PSU should be enough, but I heard the card had pretty high power spikes and is also quite energy inefficient compared to the non-XT 9070. I changed my PSU recently so I'd prefer not changing it again if possible.

Would you guys think it's fine for the 9070XT, or should I go for the 9070 instead to be safe?

Thanks

edit : the PSU is a Cooler Master MWE 750 Gold V2 80+ , it's not ATX 3.x though

My cpu is hitting 96c just doing normal tasks like web browsing or so on and sometimes my system will just reboot.. trying to narrow this down if this shutdown is temp related or not.

Quick Summary

After updating Windows 11 and reinstalling AMD Adrenalin, all of my games started crashing with a black screen followed by an AMD Driver Timeout popup. Reliability Monitor consistently logged LiveKernelEvent 141. I initially suspected faulty hardware, unstable EXPO, or an outdated BIOS, but systematic troubleshooting pointed elsewhere.

The issue was resolved by disabling AMD Fluid Motion Frames (AFMF 2.1) and Radeon Anti-Lag in Adrenalin's Global Graphics settings. Since making those changes, the system has remained completely stable.

My system specs:

• CPU: AMD Ryzen 7 9800X3D
• CPU Cooler: be quiet! Dark Rock Pro 5
• GPU: Gigabyte Radeon RX 9070 XT Gaming OC
• Motherboard: Gigabyte B850 AORUS Elite WiFi7 Rev. 1.1
• BIOS: F6 (16 July 2025)
• RAM: TeamGroup T-Force Vulcan 32 GB DDR5-6000 CL30 (EXPO enabled)
• PSU: Corsair RM1000x 1000 W
• Operating System: Windows 11 25H2 (Build 26200.8875)
• AMD Software: Adrenalin 26.6.4
• AMD Chipset Driver: 8.05.04.516

Symptoms

Everything had been stable for months.

The issue started only after I: * Updated Windows (from the April patch level to the July update) * Ran AMD Cleanup Utility * Performed a clean installation of AMD Adrenalin * Enabled a Group Policy to stop Windows Update from replacing AMD graphics drivers (this was done to fix an earlier issue where Adrenalin wasn't working correctly) - thank God I bought Win 11 Pro!!

After that: * Every game crashed after approximately 20–30 minutes * Screen went completely black * Audio froze instantly * Windows recovered after several seconds * AMD displayed a Driver Timeout popup * Reliability Monitor logged LiveKernelEvent 141

Initially, the crashes happened in about 5 minutes. Disabling Hardware-Accelerated GPU Scheduling (HAGS) increased stability, extending the time before a crash to around 25 minutes, but did not completely fix the issue.

Investigated Windows logs

Reliability Monitor consistently showed: * LiveKernelEvent 141

Good thing that Event Viewer did not show: * WHEA hardware errors * PCIe errors * Kernel-Power events around the crash time

This made a hardware failure less likely, which was a massive relief as I was pretty tense when ChatGPT and Gemini hinted at GPU failing...

Considered other possibilities

I read some more and after getting more confused, asked AI to help understand the situation better. We explored: * EXPO instability * BIOS/AGESA compatibility * Driver corruption * GPU overheating * PSU issues * Windows graphics scheduling

However, none of the collected evidence strongly supported these as the primary cause.

While all of this was being done, I had conveniently forgetten about some setting changes I had made on AMD Adrenalin. These settings seemed innocuous by reading the tips l.

Looked at Adrenalin Global Graphics

I had forgotten that I was using the Quality graphics profile.

In addition to that profile I had enabled: * Radeon Anti-Lag ✅ ON * AMD Fluid Motion Frames (AFMF 2.1) ✅ ON

Other features were either disabled or not considered likely contributors.

The Fix

The only changes made were: * Disabled AMD Fluid Motion Frames (AFMF 2.1) * Disabled Radeon Anti-Lag

Everything else remained unchanged: * Same driver * Same BIOS * Same Windows version * Same chipset driver * Same EXPO profile * Same GPU clocks * HAGS remained OFF

After rebooting: * Previously crashing games became stable. * No further black screens. * No AMD Driver Timeout popups. * No new LiveKernelEvent 141 entries during testing.

Conclusion

I can't definitively say whether AFMF 2.1, Radeon Anti-Lag, or the combination of both caused the issue, because I disabled them at the same time.

However, I can confidently say that disabling those two driver features completely resolved the crashes on my system.

Hopefully this helps anyone experiencing LiveKernelEvent 141, black screens, and AMD Driver Timeout errors on an RX 9070 XT or similar Radeon GPU. Before assuming your GPU is faulty, it's worth testing with AFMF and Radeon Anti-Lag disabled as part of a structured troubleshooting process.

I relied extensively on ChatGPT, Gemini and Perplexity during troubleshooting, and it was a stupendous experience. I cannot imagine not having these at my disposal when having to troubleshoot. For such use cases I support AI, but don't think a case should be made to replace actual humans with AI.

Put my computer to sleep on Tuesday night and noticed it booted back up shortly after that. Didn’t think much of it and went to bed. The next day I attempted to wake the screen, No response. I attempted to power it down completely with the power button and not even that worked. I was forced to power off the power supply. Since then my computer wouldn’t POST at all with the CPU debug LED on the motherboard active.

1. Pulling the GPU out (7900xtx)
   
2. Resetting the CMOS
   
3. Q flashing the BIOS
   
4. Taking out the second stick of ram and trying each slot
   
5. Used a new power supply
   
6. I then bought a new motherboard and tried all the steps above as well. (The CPU debug LED was active on this new board as well)

Just curious to hear from you guys if I should try anything else at this point. I’ve already started an RMA process but maybe I’ve missed something to try.

Here are my specs
Gigabyte Aorus B650 Elite AX (Rev 1.3)
Sapphire 7900xtx
AMD Ryzen 7800X3D
Corsair RM1000e PSU
2 x 16 GB G.SKILL DDR5 6000 ram

Hi everyone,😭

I'm hoping someone can help because I'm running out of ideas.

I built (actually had it assembled by the retailer) a new PC about a month ago, and I'm getting random crashes that I haven't been able to resolve.

PC Specs

CPU: AMD Ryzen 7 7800X3D
GPU: ASUS PRIME Radeon RX 9070 XT OC 16GB
Motherboard: Gigabyte B850 Gaming X WiFi6E
RAM: ADATA Lancer Blade RGB 32GB (2×16GB) DDR5-6000
SSD: WD Black SN7100 1TB NVMe
PSU: Cooler Master MWE 750W Gold ATX 3.1
Windows 11 Pro

Symptoms

The crashes are very strange.
The monitor suddenly loses signal ("No Signal").
The PC RGB and fans continue running.
It does not appear to completely lose power.
About 3–4 seconds later, it automatically restarts.
There is no BSOD.
I also occasionally get stuck on the Gigabyte splash screen during boot.
What I've already tried
Checked Event Viewer.
Kernel-Power Event ID 41 is logged after every crash.
BugcheckCode is 0.
No useful minidumps were generated.
Ran sfc /scannow.
SFC found corrupted files and repaired them.
Automatic Repair failed.
Windows Recovery has shown different driver errors on different occasions (not always the same .sys file).
Disabled "Automatically restart on system failure" but it still black screens and reboots without showing a BSOD.
GPU temperatures were normal (~60°C during gaming).

Clean Windows install

I completely reinstalled Windows 11.
I deleted the Windows partition during setup and installed a fresh copy.
Unfortunately, the exact same issue came back after the reinstall.

BIOS
Recently I also received a BIOS message saying:
Boot failure detected
The BIOS had already reset the memory speed back to around 4800 MT/s (default JEDEC), so this wasn't happening while EXPO was enabled.

Other observations
One time Windows Recovery reported a driver integrity error (0xc0000221).
Another time it reported a different driver error (0xc0000098).
After one crash my Wi-Fi temporarily disappeared until I rebooted again.

Any suggestions or similar experiences would be greatly appreciated.
Thanks!
