System Freezes/Crashes with SDXL Models on Windows (RTX 3060 12GB, 16GB RAM)

[GodLyons]

Hello,

I am experiencing persistent system freezes and complete crashes when attempting to use SDXL models in ComfyUI. The issue forces me to hard reboot my computer.

My system configuration is:

OS: Windows 11

GPU: NVIDIA GeForce RTX 3060, 12GB VRAM

System RAM: 16GB

ComfyUI Version: release

Python Version: 3.12.7

Model: sdxl1.0base Workflow：very simple(I try to reduce the output resolution below 1024x1024.but it's no use)

The Question: Given that the SDXL models are much larger, I suspect my system RAM might be a bottleneck.

Could 16GB of system RAM be insufficient for running SDXL models comfortably alongside the OS and ComfyUI? I would like to confirm if this is a known constraint before considering a hardware upgrade.

Any insight, diagnostic steps, or recommended settings for my hardware would be greatly appreciated.

Thank you for your work and for your help.
