Running MiniMax H3 on Low VRAM Fried My GPU, Beware

ROBOTTTTT13 · reddit · 2026-08-12

A Reddit user posted a warning after running the MiniMax H3 video model (INT4/8 quantized) on a 6GB VRAM laptop GPU (RTX 4050), which ultimately led to fatal hardware damage.

The user reported that after a few successful (albeit slow) generations, they encountered severe errors. The system threw a VIDEODXGKRNLFATALERROR and UNEXPECTEDSURPRISEREMOVAL, indicating the GPU shut down and disconnected from the system due to power issues under heavy load. After three days of troubleshooting—including clean driver reinstalls and system file checks—the GPU remains non-functional.

The author warns low-VRAM users not to blindly trust ComfyUI to protect their hardware, highlighting the physical risks of pushing heavy models on underpowered devices.
