This motherboard supports Intel® Pentium 4 Socket 478 series CPU (Willamette / Northwood). Be careful of CPU orientation when you plug
it into CPU socket.
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for mark on the CPU upper interface.
Match Pin 1 and cut edge, then insert the CPU into the socket.

This motherboard comes with a retention module attached on the CPU socket when shipped, we strongly recommend you to install AOpen
special designed CPU Fan as shown below on the retention module for better heat dissipation. Please install the CPU Fan correctly as the
following pictures shown.
1. Gently put the CPU Fan down on the
retention module with clips aligning correctly
to the four corners.
2. Pressing down the four clips with force one by one
on the retention module.
