Getting Started with Hardware

This section contains hardware-focused post-installation guidance to help you get the most out of your system after installing AtlasOS. Topics include memory overclocking (XMP/DOCP), Resizable BAR, and safely updating your BIOS/UEFI.

Quick links:

• auto: Enabling XMP/DOCP — How to enable and validate XMP or DOCP safely.
• Resizable BAR — What Resizable BAR is and how to enable it for supported systems.
• :material-system-update: Updating BIOS/UEFI — Best practices for updating firmware safely.

If you're unsure where to start, follow the order above: enable XMP/DOCP if you need memory speed, then check Resizable BAR if you have a supported GPU/motherboard, and update BIOS only when necessary and after backing up important data.
