The system reboots itself automatically when Prime95 is run

[Master]

Today I download the latest version of Prime95 and wanted to check if the system is stable.
However after several minutes it suddenly got rebooted!
Lucky me, I had all the CPU cores and other sensors temps logged.
I noticed 10 seconds before the whole PC got rebooted, the CPU temps were as follows:
RealTemp log:

So, CPU temps should not have been the cause right?
I also gathered some logs using OpenHardwareMonitor, which is attached since it cant be displayed properly here. You can also view the contents from Here
Can anyone help me find what the cause of system reboot could be here? with all the logs that I gathered?
By the way, This also happens in Ubuntu as well, so this is not pertinent to Windows 10 OS.

Thank you all in advance

Your power supply? Sounds like a cheapo horrible thing that can't keep up with your components.

 

[R-T-B]

An unstable OC can also cause reboots.

Coming from that log he's posted, doesn't look like anything's overclocked.

 

[trog100]

overclocked or not it still sounds like an unstable cpu.. or to put it another way if it was mine and overclocked the first thing i would do is slow the clocks down..

[CAPSLOCKSTUCK]

PSU would be my guess.

Check "Event Viewer" it may give more info.

 

[thebluebumblebee]

(I'm taking a guess here)
Column w starts at 48 and ends at 76. Something's warming up fast
Column X makes no sense to me
Column Z: Is this actually "Distance to TJMax"? It starts at 14 and ends at 4-5.

What CPU cooler do you have? If you're trying to run Prime on a stock HSF, it's going to have problems.
How do you have the fans configured in that case?

His sys specs say an Intel Core-i7 4790K, but the speed at load only shows 3.4Ghz. Base freq is 4.0 and turbo is 4.4 for that CPU

No clue, could be anything from memory to PSU to insufficient cooling.

Motherboards also may have VRM power cap. See if there is a setting to allow VRMs to provide more powah.

 

[EarthDog]

Crap board, Crap PSU... makes sense to me.................................why he;s seeing lower than stock clocks and rebooting...

 

[Jetster]

Try Intel extreme tuning utility. Its not as harsh or old

 

[EarthDog]

P95 isnt old (its a brutal test though). In fact, its latest updates added the aes and avx extensions in modern processors. Those are what gets the cpus so hot.

 

[phanbuey]

If your system can't handle prime, it is not stable.

If the temps are in check then a reboot is most likely caused by either memory instability or power delivery issues.

This happened unexpectedly, I used to run Prime95 for hours without any issues.
I'm using CoolerMaster Evo212
At the time of the incident, I was using Asus AI Suite3 and had the profile set on Performance preset and the fan profile on Turbo preset.
I also remember enabling Virtualization from the BIOS. I dont recall changing anything else other than those I have just mentioned.
And by the way, in the EventViewer, I get Kernel 41 Error.
I'm running the P95 again this time without running AI Suite, currently temps look like this :

Which stress test are you running? Blend? Small fft? Blend will test some memory, small fft is mostly cpu...

I see temps are ok and speeds are up to where they should be. Let it run and see if it happens again. Touch your vrms and see if they are hot to the touch...

I'm running Blend.
OK. but what does a vrm look like?

 

[EarthDog]

Those three large cubes to the left of the processor and the smaller ones to the left...

Try running small fft if blend runs for a few hours and doesnt reset.

Check the exhaust on the psu as well, see if its warm or hot.

[Master]

Thank you very much.
Okay. I'll do as suggested and report back when the tests are done (failed or succeeded)
and by the way, the air coming out of PSU exhaust is kind of cool, it's not that warm let alone hot!

 

[eidairaman1]

Clear cmos, set optimized defaults, run it again, if it does it then you could have a psu and board not able to handle the testing. My system only kicks out if at 5.1+GHz because I hit a thermal barrier with stress testing.

Thank you very much.

How are the ambient temperatures of the room the computer is in?

How are the ambient temperatures of the room the computer is in?

It's 9:22 PM here, and temps outside is about 25 C /77 F. since the door is open, the room temperature is almost the same as that of the outside.

 

[Regeneration]

Update the motherboard BIOS and check out the settings there.

Remove ASUS AI and any other on-the-fly overclocking software. If you want to tune performance and overclock, do it from the BIOS manually.

Are you overclocking? please provide more details.

 

[Master]

Update the motherboard BIOS, check out the BIOS settings, remove ASUS AI and any other on-the-fly overclocking software, and post more details about your system and if you're overclocking or not.

The BIOS is updated to the latest version since it was needed for the new 4790K.
I didn't overclock anything and currently, the test has been running without AI Suite and any other overclocking software activated.

if you are not running your gpu the system isnt consuming much power.. if it was a psu problem the resets would happen when the gpu was running..

stop running blend and run each test separately see if that makes any difference..

In the hardware monitoring screenshot you posted, the CPU voltage is too low (0.9v), some sensors report high temps (100c), can be false reading, make sure to disable any "shutdown on temperature X/Y" option in the BIOS, force all fans to 100 percent.
