Hello I have been experiencing extreme crashes on my system running Houdini indie 17.5 and 18.0.

As I am running simulations (with or without RAM caching), the system suddenly crashes:
1_Screen goes completely black, loss of input.
2_Power button becomes unresponsive.
3_Only way to shut down is through the PSU switch.

I tried on Windows 10 and Linux CentOS and both crash hard.

System specs:
AMD Threadripper 2990wx
128 GB Kingston Hyper-X Predator
Asus Prime X399-A
Quadro RTX 5000

Any help would be greatly appreciated.

The test scene Im doing is:
make pig head
apply billowy smoke shelf tool
set div to 0.015
watch it crash
Is this a bad test? I mean since the volume keeps getting bigger and bigger, should it crash the whole system?
I mean most of my volume simulations are huge in size and divs and it didn't crash on my old i7.

I believe this is due to a performance BIOS/EFI setting. Go into the BIOS/EFI at boot and disable “core performance boost” if it's enabled. This causes a lot of instability with heavily threaded apps. I don't know why it's on by default.

twod you saved my life!
i was trying to solve this problem for 3 weeks! they should really turn this off in the bios. it was set to auto and i disabled it.
Thank you so so much!!!!
