Hardware / Black Screen with Ryzen 5900X (Corona Renderer/3dsMax)

« on: 2022-02-21, 21:04:28 »

I have exactly the same problem as (https://forum.corona-renderer.com/index.php?topic=27699.15)
When it crashes screen turns black, monitor goes into sleep mode, nothing works, not even the reset button (but the PC is still ON by the fan and ram leds). I have to switch off the PSU. I updated my BIOS (v13), changed the voltage to 1.35V (1.36V and 1.37V) and changed the frequency (3000mhz, 2993mhz, 2400mhz, 2133mhz) and felt more stability but it wasn't enough. The problem persists. I still haven't found a definitive solution. Could anyone help?

The temperature spike during 5k render is 71ºC (i think Deepcool Gammaxx 400 is really good).

The build:
GIGABYTE B550M AORUS ELITE
AMD Ryzen 9 5900X
Deepcool Gammaxx 400 Ex 120mm + 3 Cooler Fans Deepcool 120mm
Kingston Fury Beast, RGB, 32GB (2x16GB), 3600MHz, DDR4, CL18
Samsung SSD 970 EVO Plus
ASUS DUAL NVIDIA RTX 3060 TI 8GB
Corsair CV650, 650W, 80 Plus
2TB HD drive

Thank You

Hey mojemenojemato
I have exactly the same problem. When it crashes screen turns black, monitor goes into sleep mode, nothing works, not even the reset button. I have to switch off the PSU. I changed the voltage to 1.35V and felt more stability. The problem now happens once a day. But I still haven't found a definitive solution. Could anyone help?

Hello everyone,

my new build is giving me headaches and I have run out of ideas to make it stable.

The PC is used for modeling and rendering in max 2016 with corona 6 (hotfix 2). When modeling or doing basicaly any other type of work, the machine is working nice and fast. But when rendering it keeps randomly crashing. Sometimes I am able to render multiple images, sometimes it crashes 2/3 into the render, sometimes at denoising. When it crashes screen turns black, monitor goes into sleep mode, nothing works, not even the reset button. I have to switch off the PSU. The symptoms are exactly the same as people describing in other posts here https://forum.corona-renderer.com/index.php?topic=27699.0.

The build:
GIGABYTE B550M AORUS ELITE
AMD Ryzen 9 5900X
NOCTUA NH-U12P SE2 + AM4 mounting kit (repurposed from previous pc)
G.SKILL 64 GB KIT DDR4 3600 MHz CL18 Ripjaws V ( 2x32GB)
Samsung SSD 970 EVO Plus
ASUS DUAL GTX 1060 OC
Seasonic Core GM 500W Gold
two other HDD drives

My first suspect was RAM. When I did memtest-86 on those RAMs, one specific address kept returning errors in one bit (10000000 instead of 00000000, or E7F7F7F7 instead of F7F7F7F7, you get it). So I tried turning off XMP without any change in behavior. Then I pulled one stick out, hoping to leave only the good one in. It kept crashing, so I swapped the sticks, still crashing.

Second suspect was overheating, but temps under render load are (from HWiNFO64) 69c for CPU die average, VRM MOS 86c, GPU chilling at 52c after 30 mins of rendering and they dont seem to creep up more.

Third suspect is PSU, but all online power calculators say it should be able to handle it with reserve. I have 750W PSU from previous pc so I can try that, but it was making strange squeak noise when AIDA64 performed L3 cache copy benchmark. This new makes it too, just quietly/differently so I assumed its a feature.

Windows event manager is not very helpful, it only says unexpected shutdown. PC runs Win10+latest updates, latest drivers and BIOS. I did not tinker with any RAM or CPU settings.

I am thankful for any ideas.
