Denoiser

Hello, I have such a problem that the noise suppressor does not work when rendering the scene, although the noise suppressor is turned on, sometimes there are errors, I suspect this because of the lack of memory, but the video card has 6 GB of memory, and in general 32 GB of operable memory, such as Can I use all the RAM so that the squelch works?

Unfortunately the ray denoiser is one bit of Iray that requires the GPU, and since it takes memory itself using it increases the likelihood of the render dropping to CPU. There is an Intel denoiser, which runs after the render on the finshed image (so you have to guess when to stop) which some people have been using.

But due to lack of memory, it turns into a processor, it turns out that there is not enough RAM? I just do not understand a bit.

In order for the GPU to be used the scene and the memory needed for working must all  fit into the GPU's memory, it can't page to regular memory. 6GB isn't bad, but it isn't enormous either - I was using the ROG Medieval Bedroom with a single Genesis 8 Female, with clothign and hair, the other day and no denoiser - it took well ver 6GB of memory, on top of anything else that was using GPU memory.
