[Solved] System reboots when I start GPU stress or use 3D soft - GTX 970

[cjr4d]

My first reaction to reading your problem was of a power-supply issue. It's typically when the going gets tough that a top-end GPU like yours will start drinking power and if the system diverts too much from the rest of the components you get a crash.

However, having said that, your PSU is a powerful one and you mention this getting worse when you change O/S version. Plenty of other builders have put together machines this powerful - and more - without the issue.

So ... Perhaps try that GPU in a different PCIe slot. I know they will be slower assuming you have it currently in slot PCIeX16 but it might be a valid check that the GPU can run in a lesser one with sufficient power (assuming you've checked the PSU leads and connectors etc). Hopefully there will be no configuration problems...

I might be way off mark but your problem sounds like power to me.

Good luck anyway

Hello, I also think it's a power problem. If I change gpu of slot... I should reinstall Sierra, multibeast or something else after?
I was about to do a new fresh installation of El Capitan, but now I think it is best to install windows to test if the hardware is good.

Have you implemented Power Management ?

I have tried so many things that it is probable, but I don't know if I did it well.
I'll try to do it right now...

I already implemented PM. This time I tried with Cinema 4d, the system was rebooted in a couple of minutes after touching some parameters, nothing complex.
I have the Power Management test on txt file (see attached)

PS: With geekbench 4.1: CUDA & Metal test don't works (Closes instantly), OpenCL works for a few seconds and it closes. I did not get any results for gpu from this software.

If I was in your position I would try a fresh install onto a spare drive.

Yes. I'm going to try El Capitan 10.11.6 (the only version that can be downloaded from app store). I hope it works, then I'll tell you. Thank you.

SOLVED!... You were right, the problem was power. My PSU was malfunctioning, perhaps because of an early deterioration. I also spoke with a PSU technician who had the same problem with exactly the same PSU. So... my advice is: never buy this PSU Thermaltake 750w Bronze. I have now a Cooler Master 720w Silent Pro, everything is perfect now.
What a fright!.. back to Windows ... ufff ... never!

Thank you all!.. Now I can sleep again.

PS: I also discovered that many benchmark softwares are liars.

I have the same issue with my config.
However my GPU gets the power only through the PCI port. It does require only 75 W.
So I am not 100% sure if it's the PSU.

What do you think?

Hello,

Have you solved the problem?

Thanks

I dont know what for gpu you're using.
I have a gigabyte one, and they had a newer firmware for my gpu,
( According to the docs, the new firmware was for "Samsung Memory issues")

I updated it and the problems were gone.


So I can recommend to check for newer firmware for the gpu, and maybe for the mobo too

Hello,

Hello,
Thanks for your answer.
I'm not even using an external GPU, I am using the internal HD 630.
I guess I must be having a different issue.
