Why is my GPU out of memory in Blender?
The short answer is that SSS on the GPU eats up a lot of memory, so much so that it is recommended to have more than 1 GB of memory on for your GPU. This was mentioned in one of the videos from the Blender Conference (unfortunately I can’t remember which one). Updating your drivers won’t really help as that can’t add more memory,…

Which is the best GPU to use for Blender?
One slower onboard GPU (typically Intel) and one faster dedicated GPU for a better performance (AMD or Nvidia). For the best performance the dedicated GPU should be used for Blender. Which GPU to use for which application can be configured in your graphics driver settings.
Do you need to install CUDA to build Blender?
If you build Blender yourself, try to download and install a newer CUDA developer toolkit. Normally users do not need to install the CUDA toolkit as Blender comes with precompiled kernels. CUDA Error: Out of memory ¶ This usually means there is not enough memory to store the scene for use by the GPU.
How much memory does blender use in a cycle?
As you can see render is starting after just 8 minutes!!! Also Blender peak memory is aroung 24Gb as I said, and the system memory is at 55Gb of usage. Why is this difference happening? Why is Blender taking so much more memory in 2.8 than 2.79.6, and also Cycles?
What was the CUDA error in Blender 2.8?
GPU Rendering issue “Cuda error at cuCtxCreate: Illegal Address” this is the link to my previous issue that got answered. I solved the problem by doing the rendering using CPU+GPU in Blender 2.8 (linux, Ubuntu).
How can I reduce memory usage in Blender?
I found that reducing tile size (under the performance tab in the render tab) will reduce memory usage. This will be slightly slower ( https://youtu.be/8gSyEpt4-60?t=671) but will consume less ram, and allow the render to complete.
