Oct 2, 2015 · When trying to render my scene with my GTX 970 and cycles I get a cuda error saying that I was out of memory. However according to gpu-z I only got up to using 3228MB of VRAM, and according to blen...

May 6, 2022 · Try command line rendering - when you use blender's render window you're using vram to display the image. Command line rendering doesn't, but you don't get to see the render as it happens.

Dec 12, 2022 · I've upgraded GPU recently because 8gb of VRAM on my old one wasn't enough, causing out of memory use or crashes in heavy scenes. However the new GPU acts similarly in heavy scenes, it crashes at around 14-15gb use of VRAM. It never uses all 24gb of VRAM.

Dec 1, 2022 · Since your GPU has 12 GB, there isn't more VRAM available. I would recommend optimizing your scene. Reduce polycount and texture resolution where it isn't visible. $\endgroup$

Dec 11, 2022 · Try a CPU render and check in the render window how much RAM was used (this will be different from the total ram blender is using; do not use system monitor/task manager). Then subtract your GPU's ram capacity from the ram used and you know how much memory optimization you have to do.

Mar 23, 2022 · Blender can use maximum 16 GB to 24 GB of RAM (OS makes decision this amount). All datas transfered from RAM to GRAM. For this reason, Blender throw error message after approximately 16 GB of RAM usage. Are you running any background programs?

Aug 3, 2023 · But there's a very easy way to find out if you're not sure. Switch Cycles to CPU rendering. If your issue was VRAM, now your scene should render fine, even if very, very, VERY slowly. If you still get an error message, you're running out of system RAM.

Jan 22, 2025 · Does using the factory startup scene change VRAM usage? Open Blender; Select File -> Defaults -> Load Factory Settings to temporarily load the factory startup file and settings; Go to preferences and enable your GPU for rendering; Change the render engine to Cycles; Render; Take note of the VRAM before rendering and during rendering and report ...

Dec 16, 2024 · Projects that rendered fine with one RTX 3060 12 GB VRAM keep showing GPU memory errors with two of them. Until yesterday, I had one Asus RTX 3060 with 12 GB in my PC. In the last three months I have rendered thousands of frames with it, and the project is basically a spaceship with several camera angles, but each project is one camera angle.

Dec 25, 2024 · With a default Blender Scene and the default cube it takes 2 GB of VRAM, when switching to cycles it goes up to 3.7 GB VRAM usage. With my old card I did not have that issue. NVIDIA Studio Drivers are updated, the Blender settings are Optix + CPU usage. I attached some screenshots as well.
