One of the most common questions from users is about maximizing performance by upgrading the CPU. However, the answer depends entirely on your specific motherboard revision.
If an aggressive memory overclock or bad BIOS setup prevents the board from completing its Power-On Self-Test (POST), look for the 3-pin configuration labeled :
One PCI Express x16 slot for dedicated graphics, one PCIe x1 slot, and two standard PCI slots. Integrated IDE port and four SATA 3Gb/s connectors. Schematic and Layout Information
When troubleshooting boot loops or bad BIOS settings, look for the 3-pin jumper block near the motherboard battery: Schematic Main Foxconn N15235 45cmx
