Posted by Gold-Arugula940@reddit | buildapc | View on Reddit | 14 comments

Hi everyone, I need some help troubleshooting a weird issue with my PC.

Here are my specs:

CPU: Ryzen 9 9950X
Motherboard: ASRock X870E Taichi
PSU: ROG Strix 1200W Platinum
RAM: G.Skill Trident Z5 Neo 2x32 (cl32 6000)
GPU: RTX 5080

The problem:
My PC randomly shuts down completely (like the power is cut, not a restart). if i using EXPO. The system was previously running completely fine using EXPO (6000 MHz) with no issues. This problem only started recently.

can anyone help fix it?

With that exact kit i had one burn out. Like Tom&Jerry type shit. It worked fine for about 2 hours on idle with expo active, then it shut down and never booted again with one of the sticks. Had to RMA the kit and got a new one in return. Then i sold it and went for 64GB CL30 6000MT/s from corsair. Try to undervolt the cpu as well. Also, do a memtest at JEDEC speeds, and try to expo and do another test after. If it does not crash during the tests, it might be the OS which is faulty and you may need to reinstall it. If it still crashes, i recommend doing a bios update if you didn't do that yet. If all comes to no happy ending, i recommend swapping the mobo. AsRock has been known to burn cpu's literally.
