Your question

After use sd3_medium_incl_clips_t5xxlfp16.safetensors model , ComfyUI is disconnected.But other model,such as dreamshaperXL_v21TurboDPMSDE.safetensors can run right.

Does the same happen using a non-T5 model?

It's likely just you're using enough of your RAM on other things that loading the full fat model with the big fat T5 on it is pushing you over the limit and the process is crashing from running out of memory.

Look at the resource usage tab of task manager while loading to see if the charts spike up to the top.

It's likely just you're using enough of your RAM on other things that loading the full fat model with the big fat T5 on it is pushing you over the limit and the process is crashing from running out of memory.很可能只是你在其他事情上使用了足够多的内存，而加载带有大容量 T5 的全脂模型使你的内存超过了极限，进程因内存耗尽而崩溃。

Look at the resource usage tab of task manager while loading to see if the charts spike up to the top.在加载时查看任务管理器的资源使用情况选项卡，看看图表是否飙升到顶部。

It's happening to me, too. I tried sd3_medium_incl_clips_t5xxlfp16.safetensors model and sd3_medium_incl_clips_t5xxlfp8.safetensors model.

I checked the resource usage tab of task manager while loading. and then the cpu and memory peak usage is less than 50% and the GPU usage is hardly up at all
