7950X After reboot computer stucks in 'PEI Core started'

Hi,

Often after computer reboot it is hanging on 'Q-CODE 10 - PEI core is started'.

I have 100% recreation test for that issue. I am opening VanceAi and try to sharpen an image, after few moments program crashes because something happens. I can verify that 'something' by running mem benchmark after the program (passmark performancetest 11.0 memory benchmark). The 'database operation' score drops from 12k to 400. When i reboot the problem happens.

To recover i have to disconnect power from power supply and wait for MOBO to discharge - annoying as hell.

 

Copmputer specs computer (1st and 2nd are other component i used for testing):

  • Ryzen 7950X
  • 1st Asus strix B650E-E
  • 2nd Asus strix B650E-E (new)
  • 1st Kingstone Fury 2x32 5600 40-40-40-80
  • 2nd Kingstone Fury Beast 2x32 5600 36-38-38-80
  • 1st RTX 4090
  • 2nd iGPU
  • 1st ENDORFY Supermo FM5 1000W 80+ Gold
  • 2nd XFX 750W

The only thing i didn't check is CPU, do you have any idea what can be wrong?

Should i replace CPU ?

If you have tried different motherboards and memory kits and the issue still persists, it is possible that the issue may lie with the CPU. However, before replacing the CPU, you can try the following troubleshooting steps:

  1. Update BIOS: Make sure that you have the latest BIOS version installed on your motherboard. You can download the latest BIOS version from the motherboard manufacturer's website.

  2. Test Memory: You can try running memory tests, such as Memtest86, to check if your memory is functioning correctly. If errors are found, you may need to replace your memory.

  3. Test CPU: You can try stress-testing your CPU using software such as Prime95 to see if it is functioning correctly. If the CPU fails the test, you may need to replace it.

  4. Check for overheating: Make sure that your CPU is not overheating. You can monitor your CPU temperature using software such as HWMonitor. If your CPU is overheating, you may need to improve your cooling solution.

  5. Power supply: Ensure that your power supply is functioning correctly and providing stable power to all components.

If none of the above steps solve the issue, it is possible that the CPU is faulty and may need to be replaced. However, I would suggest consulting with a professional technician or the CPU manufacturer before replacing the CPU to ensure that it is the root cause of the issue.

It seems that my problem is very similar to what JayTwoCent have with his system,

1. I have newest BIOS -> still problem

2. Run memtest86 -> no issue

4. Temps on benchamrk are around 75-85, so far below boost temp

5. It has no problem even on high load. Voltages are stable under load and without

 

3 to be tested soon.
