⚠️ disclaimer: spd vs real-time timings

mfetch displays spd timings — the factory profiles burned into the ram chip (not the active bios/overclock timings from the cpu memory controller).

🛠 enabling spd support

if the modules section is empty:

sudo modprobe i2c-dev
sudo modprobe ee1004

Installation

cargo build --release

Or via AUR:

yay -S mfetch
