System restarts unexpectedly when under stress
System restarts unexpectedly when under stress
Hey there! It looks like your PC is experiencing unexpected restarts, even though the RAM seems fine. After some testing—like running MemTest86 multiple times and swapping the RAM back to the old one—the issue still happens when stress is applied. I’ve narrowed it down to a few potential causes: the motherboard might be aging or underperforming, or the power supply could be the culprit. I’ve updated the BIOS, kept my drivers current, and ensured Windows is up-to-date, but nothing seems to fix the problem. I’m also considering the possibility of hardware wear on the board itself. Thanks for checking in!
During testing, what temperatures were recorded? Were CPU and GPU stresses handled independently? What was the available RAM? Is it a Corsair Vengeance Pro with 16GB, XMP enabled? Any overclocking attempts made? Would you like additional details?
I realized I missed something earlier. I was using two sets of Corsair Vengeance LX RAM—one at 2133MHz 2x8 and another at 3000MHz 2x8. That’s unusual since the speeds don’t align. Currently, my system runs a fresh G Skill Ripjaws 3200MHz 32x2 setup with 64GB, without any overclocking. I initially applied a stock XMP profile in the BIOS but removed it after noticing stability problems. CPU temperatures aren’t the issue; they only rise slightly to 55-60°C under load. In my experience, Ryzen CPUs need around 88°C before performance drops. I haven’t stress-tested either part individually, but it seems the problem arises when the GPU is heavily used—CPU stays in the 20-40% range while the GPU hits full capacity. I plan to spend up to 20 minutes in VR with the GPU at maximum load and then restart. Also, Substance Painter contributed to the problem due to its high GPU demand.
Review GPU-Z sensor panel closely. Record all details. Pay attention to power consumption and performance limits. Since the PSU might be the issue (it often cuts out instead of restarting), monitor the 12V rails while pushing CPU and GPU together. Notice any significant voltage drops—it could mean the board needs a reset. For basic troubleshooting, turn off c-states first.
