Thank you for the feedback. After switching the PSU, the system still doesn’t shut down during stress tests. It seems unrelated to overheating or the PSU itself. I tried another PSU model. During high load conditions, temperatures were around CPU 89 and GPU between 70-80, with a peak of 90.
This is quite high, isn't it?
The maximum operating temperature for 7800X3D is 89°C.
You might be experiencing thermal shutdown.
Consider using a better CPU cooler.
It seems the issue isn't resolved by stress testing. In gaming situations where it fails, it typically occurs in the 70s or early 80s.
What CPU cooler are you using? Based on what you shared, it seems like a thermal problem might be involved. How is your case airflow performing? Are there any signs of negative pressure? You may not be experiencing crashes during stress testing, but keep in mind that thermal shutdowns can occur suddenly. Your CPU could stay cool during testing, yet certain spikes in gaming could push temperatures high enough to trigger shutdowns.
Thanks for the ideas! BeQuiet Pure Rock 2 is my preferred choice. I’ve already done some repairs and re-setting it twice, and it seems to work fine. (Max TDP around 150)
I’m not experiencing any thermal throttling either.
I’m pretty confident it’s a hardware issue.
I just got a new motherboard—any chance it makes a difference?
Do you have any information about whether the CPU shuts down because of overheating?
I'm facing the same problem after assembling the machine (9950X). While playing games like FC 25 or Spiderman, it doesn't always happen. It seems random on some days but only during these games. I applied for a replacement and got a new CPU, but the issue persists. I assumed it was a GPU problem (4070 super) and received a friend's GPU, yet the problem continues. I tried reinstalling Windows and changed the Nvme, but it still works. The system doesn't shut down during stress tests. It could be the motherboard, RAM, or AIO cooler now... I'm tired of constantly replacing parts. 😛
Please let me know if the motherboard resolves the issue.
Updating the mainboard fixed the problem. When I returned it for RMA, they found bent CPU socket pins. I'm unsure if that was the original cause or a later issue, but with my new mainboard there are no more problems. I suggest trying to switch the PSU first—it's simple and likely the main fix. If you did that, then switching the mainboard might be the next step.
just an update... I sent the motherboard under warranty! They updated the BIOS and it helped, but the problem persisted. Then I found a solution on pcpartpicker.com. There was a compatibility issue with the Gigabyte board and the 9950X at higher speeds, so I switched to the Asus 870A and it resolved the issue.
