Title: Reboot your computer when rendering
Post by: ipepper on 2015-08-09, 14:38:31
tell me why the computer restarts when you render to the corona
i7 4770 computer configuration, memory 16 GB Video gtх770
when rendering a maximum temperature of 75 degrees

It could be that your psu is about to die. I had similar issues right before my unit had gone to psu heaven.

Or something else than CPU is overheating.

how do I know this?

You can google for some pc stress test and run it for several hours. If it fails it's clear that Corona has nothing to do with a problem :]

did some tests a computer's performance is poor. tell me how to solve the problem

CPU Fan dead?... or full of dust, or even power source not enough maybe?... who knows really.
Overheating... condensation... motherboard deformation due to heat... it could be anything...

Check temperatures, visit local service, ...

I did the test found that the Extreme CPU temperature reaches 86 degrees. Most likely the case in outdated thermal grease.

Remove dust from fan with a brush and check its working properly, clean the cooling unit. Do you have pets?... i have to remove cat hairs from my PC every 4-5 months. Also the graphic card exhaust must take heat outside... if tower is near a wall or something that could be difficult and heat could be recirculating inside.
Thankfully those Intel chips turns down automatically when overheating.

Yes, I cleared the computer to dust. Specialist tested iron and said that he was all okay. At increase in turns cooler temperature has not changed, we have concluded that it is necessary to change the thermal paste.

It's not just you. I have same K4770 processor and it's doing the same thing. It went up to 100 degrees Celsius. I was monitoring heat. I stopped render and it went back to nominal temperature of 35-45 degrees Celsius. During the render, my processor load was 100%, so I decided to check if V-Ray uses 100% too because that was never a issue with V-Ray renders. When I rendered test scene cpu load was 100% too, but it didn't go over 80 degrees. And it was stable. I hope there will be solution to this, because I would love to use this render engine.

This was already asked by more people before, but that's not how software works. Software cannot stress your hardware above the thermal design. Corona (or any software at all) isn't the reason why your CPU is overheating. Just because other software shows similar loads, doesn't mean they have the same stress load, some instruction sets are more demanding (like SSE, AVX ).

If you CPU routinely goes above 80 C, you simply have bad cooling, it is simple as that. If you have good CPU cooler, check if the thermal paste is applied correctly. For 1151 CPUs, a de-liding process is option. Make sure you have good airflow inside case.

If you're running overclock, make sure you stay within reasonable voltage, depends on your pure luck. If you need to run high voltages to get high over-clock, you lost in silicon lottery and simply can't afford to run such overclock.

And just as well software can't do that - can you imagine what viruses and ransom-ware would be like if it could!

Sure, pay or your PC explodes :- )

No worries, this will still be a good business model - just not with static PC hardware... think more about transportation, modern car computers and stuff :)
