A user on Ubuntu with a 5070 Ti 16GB VRAM and 32GB RAM is trying to run the default ComfyUI Minimax H3 template but keeps getting OOM crashes. They've tried various parameter combinations (e.g., --fast fp16accumulation --reserve-vram 2.0 --disable-smart-memory) without success. They ask how others with similar specs got it working.
