System Resets Intermittantly

System Specs
 

• ASUS TUF X870-P
• AMD Ryzen 9950X
• Silverstone HelA 850R
• Corsair Vengance DDR5 4x16 (64G total) 6000MHz CL28 - EXPO1 preset enabled
• Gigabyte Vision OC GeForce RTX 3080 Ti 12 GB
• OS Disk - 500GB WD Blue (temporary still waiting for NVME drives to come in)
• OS: Ubuntu 24.04

 

First AMD build, and am having issues with the system restarting intermittently. I will be running a code compile, or something like factorio, or even just web browsing and my system will drop back to the motherboard boot image (press del for bios etc.). The experience is very similar to someone pressing the reset button while the system is in use.

My gut is telling me this may be an issue with power management as initially this was happening quite often, every 15 minutes under load, but that was due to not having the sense pins plugged into the PSU (honestly never seen that come off of the 28 pin connector like that back into the PSU, would love to know what that does). On plugging this in, I now only get the hard reset at varying intervals depending on load. Ieft the machine online idle overnight to test and it had reset somewhere throughout the night.

 

Dmesg doesn't contain any errors other than some nvidia driver issues which also occurred in the intel machine i brought it over from. I suspect from the suddenness of the reset, the OS wouldn't have time to react.

 

My thinking is maybe an issue with the CPU voltage dropping causing a system reset but was wondering what others might think. I had a hell of a time finding a new in box platinum PSU from a brand I recognized so i don't want to jump to replacing it if i don't have to. I've also heard about memory issues running high speed memory dual channel so i don't want to rule out a memory configuration issue.

You tried running with the GPU removed ? I think you may be experiencing power spikes from the GPU and the PSU goes into protection mode when that happens. It is unfortunate, but you may need a bigger PSU to handle that CPU + GPU combo.

I have not, but the system is only supposed to have a max TDP of just under 700 watts i would have figured 850 would have been more than enough. Unless pcpart picker is outright just wrong by that high of a margin https://pcpartpicker.com/list/TdYWt3
