Ryzen 5 8600G – Freezing, Black Screen, Driver Timeout (Seeking Insight & Sharing My Fix)

Hi everyone,

I’ve been dealing with serious stability issues on my newly built system using the Ryzen 5 8600G APU. While I’ve managed to get things stable for now. I’m sharing my steps here not just to help others, but also to hear your opinions:
 Has anyone found the actual cause or a better/cleaner fix?

System Specs:

  • CPU: AMD Ryzen 5 8600G

  • Motherboard: ASRock B850 Pro-A

  • BIOS: v3.20 (latest as of April 2025)

  • RAM: Kingston Fury Beast DDR5 (KF560C30BBE-16), 2x16GB

  • PSU: CoolerMaster MWE 650W V2 80+ Bronze

  • OS: Windows 11 Pro 24H2 (clean install)

  • Drivers tested:

    • AMD Adrenalin 25.3.1 WHQL and also versions before, same thing happens.

Issue Description:

Immediately after assembling the PC and installing the OS, I experienced:

  • Random freezes: mouse + keyboard would stop responding for ~1–2 minutes

  • Then, a black screen followed by a system recovery and AMD popup:
    “Driver timeout has occurred...”

  • Event Viewer logs showed LiveKernelEvent 141 with amdkmdag.sys listed

This happened even during light usage like browsing, watching videos, printing, viewing images, etc.

Troubleshooting Steps Taken:

  • RAM tested using:

    • Default BIOS settings

    • EXPO profile

    • Manual tuning (based on Buildzoid’s DDR5 guide)

  • Cinebench 2024 stress tests ran fine (CPU temp ~95°C)

  • No BSODs, just freeze/black screen/recovery

  • Updated all drivers and BIOS

  • Did not reinstall Windows again

  • Did not disable hardware-accelerated GPU scheduling

  • Did not remove a RAM stick for single-channel testing

What Solved It:

The system became stable after adjusting the following BIOS settings (under OC Tweaker) or disabling Core Performance Boost option.

  • Selected: Cinebench_Profile_1

  • Enabled PBO, with Curve Optimizer set to -20

  • Set TDP Boost Limit to +85

Since making these changes, I’ve had zero issues. System is fast, responsive, and stress-free.

What I’d Like to Know:

  • Has anyone narrowed down the real reason for these issues?

  • Are the BIOS defaults simply too aggressive for the 8600G’s iGPU + SoC power behavior?

  • Is ASRock’s BIOS to blame, or is this common across boards/brands?

  • Any other BIOS tweaks you’d recommend for better thermals or efficiency?

Thanks a lot for reading — and in advance for any input. I hope this helps someone out there, and I’m looking forward to your insights.

Best regards

Yeh. This problem buffles me for days. I've got 8600G relying on IDG. The trick I found works is to limit the Max CPU Staten in Windows advanced power settings when editing power plan. I set min state to 5%, and max state to 90%.

Another thought, as I spotted the same issue with a 8500G after swapping out the ram for the 8600G. The ram I swapped out is able to get the 8600G through POST, but won't be able to load Windows or Debian. The 8500G was working fine till I swapped the RAM. Same driver time out issue. Thus, I reckon the problem is RAM compatibility issue. Another thing that I noticed is that 8600G only runs a tad above 70 degrees, with the stock heat sink and fan,,even under stress test. Before, it can run up to 95 degrees. Though I found that even when the CPU is cool, the issue persists as long as it hits full speed. Above all, it might be a design issue with the CPU and just a bad batch.
