I'm on a scene with about 9 M triangles and 4Gb ram used (with almost 11 G free) and , adding an object of about 500k triangles I've received a Render Failure message.

Seeing on log Windows I see these errors:

CUDA error 1 on device 0: One or more of the parameters passed were not within an acceptable range of values.
-> failed to bind texture to device memory (data5)
device 0: failed to bind data texture 4 of context 0
<<< Render Failure >>>

Where do you suggest to investigate ?
The object added is a tree with several mix materials that alone in a scene test rendering correctly without errors.

EDIT:
the issue is not related to this particular object, it seems that I am not able to add no more complex objects to the scene.
But I am sure that I'm not near the GPU limit (as I said before).
I'm working with 2.23.1 RC3

I think it's insuffient vram. Try to delete all materials and render. Where do you render it and check free vram?

Thanks for your answer, I see on LV info: EDIT:
I try to render in LV. Now I'm on 2.23.2 RC1, still same failure.

Very strange, I've about 200 objects in the scene and about 70 materials...
EDIT2:
another information that could be useful: I've usually test and save all my objects in the Content Browser, so the trees (and the texture) that I've tried to put in the scene comes from there.

If someone think to help me I can send the project via WeTransfer...

Ok I've found the problem:
as you can see in the picture I've a total of 32 Gb RAM on my system, but "cached" I've 12GB, so during the starting phase of rendering my RAM goes to zero and I've the "Render Failure error"
I think that some system RAM is shared with my video card, but I don't need that since I've 12Gb vram on board.

So,I ask you if someone coud teach me where I have to set this parameters on my system ?

If you don't use object tag and use "send all scene data", it will consume big ram while exporting. Try to check method and put object tag to some big meshes. It will seperate the ram usage on export for tagged objects.

Thanks again for your reply.

I always use "resend only update objects" , and also adding the object tag I've again the error.
In the present session (I've rebooted the PC) the cached memory is "only" 4Gb and I've enough RAM but again the same Render Failure.. it drive me crazy...

Can I send you the scene (it's about 600Mb)?

ok, send me.

Is there a dedicate section here in order to send you big file or can I send you by Wetransfer to your e-mail?

Think to solved: report here the reason of the trouble if someone is interested.

I have created a grass material with a wrong kind of displacement (wrong map I suppose, must investigate deeply), removing the texture inside the Displacement channel the problem is disappeared, so I'm able to insert again object in my scene.
