PC will reboot sometimes when gaming

[Trompochi]

I had a similar problem with my recent upgrade to 5800x and 4x8gb crucial ram (listed on system specs), the mobo was updated to latest bios 3602(AGESA 1.2.0.1) and as soon as I changed ram settings the system would restart (no BSOD) under almost any kind of load, event viewer had a new "kernel power" entry with each of those restarts. With that bios it was only stable at default ram speed of 2666mhz.

After reading a LOT of posts and changing a bunch of settings that didn't fix the issue, I decided to downgrade the bios to version 3405, now I can use DOCP (@3600mhz) and not a single reboot in 7 days of gaming/testing.

Thanks for sharing your experience. I might try downgrading to 5809 and see. I upgraded for agesa 1.2.0.0. I waited until bios wasn't beta lol

(no BSOD) under almost any kind of load, event viewer had a new "kernel power" entry with each of those restarts.

Sounds like a buggy BIOS rushed out that's egregiously cutting the power literally and then turning back on rapidly. I have seen a wrong/bad BIOS cause a false power-limit-exceeded report before. (albeit that was with a GPU)

This used to happen to one of my systems (Random shutdown/restart without BSOD) in the past and the problem ended up being one of my PSU cable extensions. Might be worth unplugging all PSU cable extensions/splitters if any, fan/rbg controllers and your front panel I/O.

Better yet, might be worth building the machine outside of your case with minimum to POST - RAM, PSU, CPU plugged in - short the power pins with a screw driver to turn motherboard on then test. This will help you stop chasing ghosts and will limit the problem to fewer components.

I will if nothing works.

but Right now, I tried running 3000 after 2133mhz was running fine. Prime was stable for 12 hrs, so this morning, I tried playing, 6hrs, no crash. I'll monitor this how it goes

 

[ChristTheGreat]

still testing, 3000mhz CAS16, no crash for 2 big gaming sessions of 6 hours. I'll cross my fingers

Sooooo, seems ram is an issue.

2666 and 3000 no crash. By the way there is a other issue I found. It did not work 3200 with and without ups

3000, no crash, but as soon as I plugged back the PC to the UPS, i had a freeze (its a simulated sinewave). Just ordered a true sinewave to test it and see.


Thank you again guys, I do really appreciate.

Now I'll give a shot to curve optimizer and if not, a lower voltage again, because its not summer yet, and gaming, cpu runs around 78-80C. It might Reach 90 so I want to lower a bit

ROG STRIX X470-F GAMING BIOS 5843
"- Update AMD AM4 AGESA V2 PI 1.2.0.1
- Support Smart Access Memory for Ryzen 3000 Series Processors
- Fix the L3 cache performance in AIDA64
- Improved system performance
- Improved system compatibility
- Improved memory performance"

I'll give it a shot to see it the ram can run back to 3200, or it will stay to 2666 for now, until a build my 2nd PC.

Disable "Global C-State Control" in the BIOS. Fixed every single random reboot on my 3900X. Not sure if it will help here but worth a try.

I have an update on what fixed C-states rebooting my system on idle. 3900X with ROG Strix B550-F. It was my VDDG IOD voltage. It was set too high by my board. 1.05v to be exact. I lowered that to 0.950v to test it out, and what do you know, two weeks strong with no WHEAs or idle reboots, even during overnight true idle sessions.

I also found out my board set SoC to 1.1v for no reason (overkill for 3600 CL16), and that it works perfectly fine with the SoC at 1.0v, both VDDGs at 0.950v and VDDP at 0.900v. Play around with those, but especially VDDG IOD.
