⚠️ disclaimer: spd vs real-time timings

please note that mfetch displays spd timings, not the active (real-time) timings from your bios.

• what does it mean?: you are seeing the "factory passport" data burned into the ram chip by the manufacturer (crucial, micron, samsung, etc.).
• why not real timings?: active timings (like xmp, docp, or manual overclocking) are stored in the cpu's memory controller. accessing them requires complex, hardware-specific drivers that vary for every cpu generation.
• the result: if you tightened your timings in the bios, mfetch will still show the default factory profiles fetched from the spd eeprom.

🛠 enabling spd support

if the modules section is empty, your system lacks access to the i2c bus. follow these steps:

1. load the drivers (for ddr4/ddr5):

   sudo modprobe i2c-dev
   sudo modprobe ee1004
   

Installation

Build from source:

cargo build --release

Or install via AUR (once package is added):

yay -S mfetch

Usage

# Requires root privileges to see detailed memory module info
