Hi all. I'm hoping someone can offer some advice on this one please.

During gaming sessions my computer is randomly rebooting. Just completely cuts power and then instantly starts up again loading to the desktop. No down time.

I'm in the process of eliminating parts and have had the CPU in eco mode, the ram voltage has been run in non expo, also upped the memory voltage and have since replaced the PSU to an 850w platinum unit, nothing has helped.

Has anyone been through this or what steps could people offer me to try?

The system:
Ryzen 7600x
Asus B650e-i mini itx mobo
32gb Kingston fury ddr5 6000mhz
Noctua u12a CPU cooler
Nr200 case using mesh - 2 intake fans on the bottom, 2 in the top, CPU cooler drawing in air from the rear of the case.
3080 founders edition
Phanteks revolt 850w mini itx psu

Thank you

Edit - the bios is up to date also

Have you been monitoring your CPU and GPU temperatures? What are they like?
Failing that, if you've swapped the PSU out, then I would say it's most likely a faulty motherboard, or the board is shorting out somewhere.
Have you tried running it outside of the case?

All overclocking off? What about PBO?



Has been run in EXPO while using the stock frequency (probably 4800), or while running 6000?

Yes all overclocking off and no PBO used. Expo only seems to put it to its rated 6000mhz but in the bios I can choose to run it at a lowest frequency. Will try that.

I'll also try the memtest and also one stick of each dimm on its own and report back.

Not looked at them closely but I do have a glimpse at them during a cinebench or furmark test and both never reach the point where they thermal throttle. The GPU temp doesn't stand out to me but the CPU gets to around 85c which is well within limits I hear.
 
It might not be a gpu driver issue, but you could try reinstalling them with the driver only setting and then you won't have the amd control panel. This has caused me random restarts before on a similar card and is a known issue.
 
Is your gpu in a standard horizontal position? If so it looks like hot air expels up into your cpu area perhaps caused your 85c.

If in vertical then some of 85c cpu air is being sucked into your gpu.

Is this a recent problem?

Try leaving the side panel off and switch off your top and bottom fans, then play a few sessions to rule out airflow and temp issues. You have a lot of positive airflow which isn't bad but can work against you in small spaces.

Right click on the Windows start button and then select "Event Viewer" from the menu.
You want to view the "Administrative Events" and scroll down the event list to when the machine last shutdown on error.

So I looked at the events log as I've had a recent crash. Critical error and just listed that the computer powered off unexpectedly. No reasons.

I'm now thinking the board. Bought from overclockers. I've emailed them, no reply which is poor.

GPU is in the normal position. The CPU fan orientation is to bring fresh air in from the back of the case so I don't believe hot air from the GPU is causing high temps.

That high reading is on a known to be hot Ryzen 7600x and in cinebench. I'd consider this normal.

I checked temps during the gaming and both GPU and CPU were all normal...

I should've mentioned that the 3080 founders I purchased to replace a 6900xt and I had the same crashes then too.

Another item I've tried. I'm literally now on the last of the components - CPU and motherboard
