Stable Diffusion ReForge causes PC freezing [SOLVED]

[N0xturn]

Hey, my pc starts to freezing when it tries to apply HiresFix or at the end of a Image generation (99%), what I discovered is, that the RAM usage spikes up to maximu. I had these problems not before, they came more or less randomly.

I use a
RTX4070 12GB VRAM
AMD Ryzen 5 5600X 6-Core Processor
16 GB RAM
Windows 11

like I said, had not problems before with this setup.

My bat config:

set PYTHON=
set GIT=
set VENV_DIR=
set COMMANDLINE_ARGS= --no-half --no-half-vae --precision full --cuda-stream --pin-shared-memory --opt-sdp-attention --listen --enable-insecure-extension-access
set SAFETENSORS_FAST_GPU=1
set PYTORCH_CUDA_ALLOC_CONF=garbage_collection_threshold:0.9,max_split_size_mb:512

(no --lowram didnt help...)

EDIT: One more information far back I used an older version, where I had the problem, when I wanted to change to model it loaded really long and caused sometimes freezes too

Wrong fork [SOLVED]
