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

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.

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?

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.

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.

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.

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

If it's software releated problem (that includes windows itself) sometimes it's hard to pinpoint the conflict so wiping the computer clean gives you a fresh starting point.

Certainly something that I could try but hard to think this is the issue.

It can sometimes take up to 45 minutes for the computer to trip and reboot.

We've all mentioned thermals but a computer that has thermal issues usually turns itself and stays off for a while to protect itself.

This has to be hardware but I'm willing to try anything to resolve it.

Ref the Overclockers lack of contact, would it be worth going straight to Asus?

does the pc switch off and then power back on? sounds like the cpu could be hitting thermal limits, i'd check the cooler mounting, how are cpu temps at idle and what does it reach under load?

It acts as if you've just pushed the reset switch. The CPU only throttles during a stress test and at 95c. During the game it gets to 67c. Not even close to it's limits. At idle it just fluctuates up and down

I think i've figured it out, I read not long ago here on the forums, owners of fe 30 series cards with ddr5 are having problems with ddr5 overheating from the flow through design of the fe cards when they are under load, DDR5 is very funny if it gets hot and can cause all kinds of problems

If you can point a spare fan at your ram and start a game up and see what happens, if your memory supports temp readouts download hwinfo64 and there should be a memory temp readout within, if so you want to keep below 70c ideally for ddr5.

As I've mentioned already, the issue was present when I had a Radeon 6900xt also

Yeah, swap that cable out just to rule it out.

I had something almost the same happening on my n45l, wrecked my head for weeks.

Swapped the cable and I've not had that issue since.

Will do but as I say it's a new PSU with new cables. Same issue on the old PSU . Going through the process of running the games single stick at a time in alternate slots.
