Is 16Gb of RAM is too low for blender? It’s constantly crashing to desktop, mostly during rendering. Task manager shows 100% ram usage. Should I get some another 16gb module or it doesn’t matter anyway?

It depends on your scene, but if it will not fit comfortably within your VRAM (and remember, your VRAM also has to house your display), then you will experience problems, in which case CPU is your only option.
You can try optimising your scene (e.g. adaptive subdivision is very memory hungry, so if you can get away with bump/normal instead, do that). Don’t use textures bigger than you need, etc.
I though that for Nvidia, Blender applied a patch that memory buffer wouldn’t crash. Also what exact error is being displayed (usually there should be an error out of GPU memory erorr or something simlar.
If it is just a VRAM issue, then Fully agree with Roken.
A “quick” tutorial that showed up in my youtube list on how to resize materials directly in blender.
Could you upload a screenshot or two of the scene you’re trying to render? The blend file would be better. 16gb should be more than enough for most scenes. If you have lots of 4k image textures, then that would eat RAM pretty quickly. As does multires and subsurf. But again, there would need to be a lot going on.
Nothing special really, basic room scene. What is interesting here is that when it crashes, I’m loading the same scene with same parameters and it renders fine. It doesn’t crash twice at a time, just randomly. This tells me that blender just gives up when it needs more ram, when I’m restarting it uses fresh ram without being filled up during work in viewport. My system is stable, no hardware problems whatsoever.
