Crashing on a large scene

Hi,
I have this pretty big scene with many houses and vegetation. I use MS to scatter 30mil grass objects. At first I could only use 10 and make them bigger but then I discovered a vray instancer option which enabled me to use 30 mil. Still after a few frames the scene crashes. System has 64GB of RAM. I'm using vrays conserve memory option too and I unchecked don't delete cash option. Oh and I'm already using camera optimizer too.
Any ideas what else to do?
I'm using MS 1.623

difficult to say without seeing the file, are you able to send it?
does it happen due to amount of objects?

Hey...sorry, stupidly I forgot to use camera adaptation. I mean for the render from above you can't really see grass anyway. So now that I've enabled it it seems ok. Will test without camera adaptation when I receive extra RAM in a few days :)
Thx

Hi,
can you advice me if this is a correct approach. So like I said I have a huge scene and I would prefer to have one MS for the grass since I have one ground object. Since the area is so big I noticed I'll actually need like 70mil grass object units. It was ok with 40mil but it just crashed now so I'm not sure if it's because I put 70mil or something else. I mean if I put 70 mil it still only generates the grass units that are in cameras FOV and in its distance?

Just got extra 64GB of RAM and I just rendered all the frames fine. Not sure if it's only that or due to restart. So now everything seems ok. And I used 80mil grass units with FOV and distance optimizers of course. That vray instancer is awesome. Are there any updates to it since I see it's WIP? And would still like to know if my approach is correct.
