@ Juraj Talcik
@ rowmanns
@ GeorgeK

Guys, thank you VERY match for your advice and tips. I have tried default RAM and some other frequences and problem persists. There was one thing with an effect - to change quad channel to dual channel. But my render time was very slow  (50% slower), because quad/dual is unfortunatelly important for rendering. @rowmanns has a very similar PC (same CPU and MTB) and no problems, so maybe I have to try different RAM or MTB or both.
Now I have to do some tests and than give you some feedback.

Hi everyone again,

I have exactly the same problem like some users around the world. For example - https://community.amd.com/thread/236638
The man from the AMD community described the problem in detail. I can´t find any solution of the problem with PC crash black screen. When I say "Crash", I mean the screen goes black and there is no image on screen. The keyboard doesn't work. Even the power or reset buttons don't work - I have to remove the power cord and re-plug it in physically. There is no bluescreen or anything. It just stops working. The log of events simply shows that the previous shutdown at <time> was unexpected.
I've tried everything, absolutely everything. It means update all drivers, bios, windows etc., change MTB, VGA, RAM, power source.... My computer with AMD 2990WX is 100% stable (a lot of synthetic tests, Vray- 100hours stable rendering etc.) except of the situation when I am using Corona render. After a few minutes or hours PC crashes.
Please, is there anybody here who have experienced the same problem and found any solution of it?
I'm really desperate...

Here is my PC specs:
CPU: Amd threadripper 2990wx 32 core procesor
VGA: Nvidia geforce rtx 2080
MTB: Asus prime x399-a (bios 1002-amd agesa summitPI-SP3r2-1.1.0.2)
RAM: Corsair Vengeance LPX DDR4 128GB (4x32GB) 3000MHz CL16
HDD: Kingston SA1000m8480g
PSU: Seasonic focus plus 1000 gold
COOL: Noctua NH-U14S TR4-SP3

Hardware / Black screen with Corona Renderer/3ds max/AMD 2990WX

Hi everyone,
I have a problem with Corona renderer - it crashes to black screen during the rendering. The problem probably caused by a weak VRM on my motherboard. Is there anybody here who has experienced a similar problem with black sreen crashes? And the other question is, Is there anybody here who has AMD 2990wx, using 3ds max and Corona render and doesn´t have any problems with rendering? If the answer is yes, can you put here you motherborad specifications or PC specification CPU/BOARD/VGA/RAM/PSC? I have tried almost everything and can't find any solution....
