According to the requirements, it should work
Detailed Requirements
- RAM: 1GB is the strict minimum. Running add-ons smoothly may require more depending on your setup. [1]
- Storage: A minimum of 4GB to 8GB is needed for the OS and cache. Larger media should be stored externally, and you should install LibreELEC directly to a drive (HDD, SSD, or SD card) rather than running it off a thumb drive for optimal performance. [1, 2, 3]
- CPU & GPU (Generic x86-64): Requires an x86-64 processor. For basic HD playback, older processors will suffice. For 4K resolution at 60Hz and 10-bit HDR, you'll need modern integrated graphics (Intel Apollo/Kaby Lake or newer, or Vega-based AMD APUs) to handle hardware decoding.
