Are there any issues with the iGPU in Ryzen?
Setup as described follows: ASRock B650M Pro RS, Ryzen 9 7900, RX 7600 XT, 64 GiB (2x32) Kingston FURY KF556C36BBE-32 (EXPO off, default timing profile), OS includes Linux, Windows 10, and Windows 11.
Issues appear only with the iGPU in GPU-accelerated applications, showing strange visual artifacts. The discrete GPU works fine, and memory tests with Memtest86+ show no errors.
I noticed that higher iGPU load reduces these artifacts, especially in games; clearing the dGPU, re-seating RAM, and testing different slots or connections didn’t resolve the problem.
It seems the issue might lie with the CPU, but I’m unsure before filing a warranty claim. I don’t have another AM5 test bench available.
Would you like suggestions for further troubleshooting, or should I consider sending the CPU for repair?
Thanks in advance.
I don’t see any other possible reason besides the processor. Consider verifying all processor voltages with hwinfo (vcore, vsoc, vigpu, etc.). It’s especially useful to test Vigpu under both load and idle conditions.
The images indicate the CPU might be heading toward failure. I’d think about initiating an RMA to check if AMD can replace it, and you should seriously look into switching to a different motherboard. If that’s not possible, ensure you’re running the most recent BIOS version. Then, with more conservative settings, adjust PBO power limits using a negative voltage curve as your next best approach to address the problem now or when you obtain a new CPU.
Only proceed with these steps if you feel comfortable modifying BIOS settings. Also, verify each change thoroughly.
Enable AMD overclocking first.
Given your DDR5 5600 RAM in a 2x32GB configuration, set the SoC voltage to 1.15v, and increase up to 1.18v if you plan to overclock to DDR5 6000.
In the PBO power limits menu, configure PPT to 142w/ TDC to 110A/ EDC to 150A. These adjustments will restrict the CPU’s power draw to approximately a 105W TDP from its 170W maximum. You may experience around a 5% performance drop or up to 10%, but stability should improve significantly.
In the Curve Optimizer menu, apply settings for all cores and set each core to a negative value of -15 (-15).
Alternatively, you might consider setting a thermal throttle temperature limit between 80–85°C, though this may not be necessary if your CPU cooler is adequate.
It seems like something I should have addressed earlier might still be affecting me. I've been running this system for about six months now, and the iGPU problems started right away. I'm using the standard AMD cooler, but I'm concerned it might break the warranty.
