How much VRAM does ComfyUI-MacMemoryMonitor require?
ComfyUI-MacMemoryMonitor requires a minimum of 128MB (0.1GB) of VRAM for base operation. For optimal performance, a GPU with at least 4GB of VRAM is recommended. This node supports low VRAM mode for resource-constrained setups.
Can I run ComfyUI-MacMemoryMonitor on an RTX 3060, RTX 4070, or RTX 4090?
✅ RTX 3060 (12GB): Yes, fully compatible with 10.7GB headroom. ✅ RTX 4070 (12GB): Yes, fully compatible with 10.7GB headroom. ✅ RTX 4070 Ti (16GB): Yes, fully compatible with 14.3GB headroom. ✅ RTX 4090 (24GB): Yes, fully compatible with 21.5GB headroom
How much VRAM does ComfyUI-MacMemoryMonitor take on an RTX 3060 vs RTX 4090?
On an RTX 3060 (12GB VRAM), ComfyUI-MacMemoryMonitor runs smoothly on an RTX 3060 (12GB) with 10.7GB of headroom. This is sufficient to run the node alongside standard SD 1.5 and SDXL workflows in full precision. On an RTX 4090 (24GB VRAM), the node runs with extreme headroom on an RTX 4090 (24GB) with 21.5GB of dedicated headroom. This allows you to combine the node with massive models (like FLUX.1 Dev, Schnell, or Hunyuan Video) in full precision (FP16) without any offload flags.
What Python packages are required for ComfyUI-MacMemoryMonitor?
To run ComfyUI-MacMemoryMonitor, you need to install: psutil. You can install these using pip or add them to your requirements.txt file.
How can I reduce VRAM usage when running ComfyUI-MacMemoryMonitor?
ComfyUI-MacMemoryMonitor supports low VRAM mode. To reduce memory usage: (1) Enable --lowvram or --medvram flags in ComfyUI, (2) Reduce batch size to 1, (3) Use fp16 or fp8 precision if supported, (4) Close other GPU applications.
How do I install ComfyUI-MacMemoryMonitor in ComfyUI?
To install ComfyUI-MacMemoryMonitor: (1) Navigate to your ComfyUI/custom_nodes directory, (2) Clone the repository: git clone https://github.com/stratopause-lsc/ComfyUI-MacMemoryMonitor, (3) Install dependencies: pip install -r requirements.txt (if present), (4) Restart ComfyUI.
