Troubleshooting sudden restarts

[sce2aux]

Recently I built my own PC. Now, I am running into a weird issue with it.

 

Whenever I am playing a game (Borderlands 3 and Battlefield 5 to name a few) my PC will occasionally restart mid-game. This does not happen consistently. Sometimes I can play and have no issues, sometimes it will restart: shut down and then power back up. This issue does not occur anywhere else, only when playing games. Another thing of note is: once the PC restarts, it will not do it again before you restart it or turn it off.

 

I can't figure out what is causing this issue. I have ran FurMark tests, Memtest and different system stress tests. None of them caused the issue to appear and none detect any system problem. I also see no errors in the system log.

 

Any ideas what might be causing this issue?

 

Specs are:

• CPU: Ryzen 3700X
• GPU: Radeon RX5700 XT
• MoBo: Gigabyte Aorus X570
• Power: Corsair RM850x
• RAM: 2x 8GB GSkill Trident
• Storage: Samsung 970 Evo Plus
• CPU cooler: be quiet Dark Rock Pro 4
• OS: Windows 10 Pro 64bit

It can be caused by XMP. Do you have it enabled?

Yes, I think I do. I will try turning it off and see if it solves the problem. Do you know why XMP can be the problem? Memtest64 did not detect anything out of the ordinary.

Well from personal experience. My board didn't enable all the subtimings listed in the profile so I was tormented by random restarts of my machine. I was later messing about in UEFI, just looking closer at what was in there and I noticed the timings in XMP listed under SPD information. I compared that to what was enabled in RAM timings and then I saw most of them was set to auto, with auto not being the value in SPD.
