Blue Screen on render

Post by ideally » Mon May 13, 2019 9:00 pm

I am trying Simlab on a trial license with a view to buying Rendering software.
My setup is:
Intel i7-9700K, 32Gb Ram, Windows 10.0.17134, NVIDIA RTX400 8Gb, GPU driver (09/04/2019), SimLab Composer 9 v9,1,19

This is a new, professionally sourced workstation whose rendering capability has been tested already,

When I attempt any kind or rendering of the simplest models, I can hear a fan picking up speed and then after around 10 seconds I get a blue screen: Stop code: WHEA_UNCORRECTABLE_ERROR.

It is tempting to finish the trial here but I thought I would run this by you guys to see if anyone knows of a quick and simple fix or setting I should have.

Thanks, Ideally

Is the machine overclocked.

The renderer utilizes all cpus in the machine, we know that overclocking the CPU high may cause and issue with rendering.

Hello ideally,

To know if the issue is really related to CPU, I suggest you to monitor the maximum temperature that the machine reaches during rendering using a dedicated 3rd party program, such as Core Temp or HWMonitor. I know, I know that you said it is already a tested machine, but from a renderer to another or even from application to another the story becomes different. Just give it a try.

If you tried to search for the error code, you find that it is a hardware error. Please check here.

Thanks to Simlab and Jsaid for the suggestions, which are spot on.

I contacted the PC vendor about the issue because I realise that BSOD really means hardware. They confirmed that the processor is overclocked. Before I had an aswer, I tried a couple of other (inferior in every respect) rendering packages, and they also failed.

BIOS is now reset, Simlab is now working perfectly and I have to say I am bowled over by the beautiful images I can now get from my CAD package. Jaw dropping! Thank you. I'm looking forward to a new paradigm of engineering illustrations,
