BAR1 went from 256 MiB to 16 GiB on an RTX 3080 and to 8 GiB on an RTX 3070 without the NVIDIA driver parameter the tweak guides recommend.

How I decoded a proprietary BLE tire pressure sensor protocol from scratch, with no docs, no SDK, just raw hex bytes, a Python script, and a drive on the Autobahn.

Web UI caps the threshold at 70°C. Router idles at 65°C. Here's how to override the fan config over SSH when you suspect heat is causing random restarts.
