New scene making studio freeze then everything acts stupid

VolvoB10M

I just bought the cabin scene but now every time I start a render it freezes completely and after 3-5 minutes it starts making stupid beeping noises, I have now also got everyone telling me there is a virus causing this. Because of that as well as a gateway popup in chrome that appeared just after an adittional orange bar was spotted above this site. What is going on with this?

Which cabin scene?

What are your computer specs?

I use AMD B350M with Ryzen 5 2600 and 16GB Ram. GPU is Nvidia GTX 960. The cabin is the one with the loft and the bed on it (FG cabin?) Other scenes are rendering slow now but the one just crashes. I did Ctrl+I but that had no effect.

If it's "Fugazzi's cabin"(https://www.daz3d.com/fg-cabin ), you're probably exceeding your available system ram.

In a quick test, My system ram usage hit 18.5GB for DS, with the RTR(ready to render) scene loaded.

"Iray Memory assistant", shows a texture usage estimate of ~13GB.

Gonna need to delete assets out of the scene, or use "Scene Optimizer" to reduce texture sizes to try to fit in your system ram.

 

If your system is  producing a noise, my first guess would be you've got a bigger problem on your hands.

Might want to run a stress test, Aida64 or others, to make sure you're not looking at an impending part failure.

If it is FG Cabin, you need to delete almost everything from the scene, reduce the textures and you may still have problems with it, that scene will strain even the higher end systems.

The GTX 960 has 4GB's of VRAM as far as I remember, which means that your Iray renders will be done on CPU which will take about ten times as long as on the GPU
The minimum usable amount of memory would be 32GB's, unless you are using older assets with lighter textures.

How do I tell how much ram will be used before I attempt to render the scene?

GPU-Z is handy utility to see what's going on;

There is no other way to check how much RAM or VRAM is going to be used than starting the render and checking the rendering progress (or the log, Help->Troubleshooting->View Log File)

Once you open the log, pin it to your taskbar, so you have easy access to it when ever you need.

As a reference, I have attached a chart, which I made some time ago for another question.

Case A) was just one G8 figure with lightweight clothing and hair and 3 spotlights
Case B) was four similar G8 figures with some architecture and 3 spotlights
Cases C and D) Same as B, but increased SubD on the figures to see when the rendering would drop to CPU and what would happen to RAM usage

Using W7 Ultimate, RTX 2070 Super (8GB) and 64GB's of RAM

Only the first case would render on your GPU, and the second would already use your harddrive to fill in for the missing RAM.

I think the FG Cabin uses all your RAM and all of your swapfile, ie. hits a ceiling without knowing what to do.

Why are there four RAM columns? Which is for the active load?

RAM/GB is the current RAM load
VRAM/MB is the current VRAM load
DeltaRAM is telling how much the usage changed from the previous line, as does the DeltaVRAM

DS Log/GiB is the total amount of VRAM used by rendering as reported by the log 

VRAM is what you have on your GPU

That is confusing with the Delta information. There used to be a simple CPU & RAM gauge on the desktop gadgets on Windows 7 but those don't exist on 10.

Delta is just a mathematical term for change.

Case A, line "DS Started", RAM load is 5GB's, DeltaRAM is 0.6GB's, because RAM load without DS was 4.4GB's (5 - 4.4 = 0.6)
