5. Troubleshooting

This section addresses common issues you might encounter with your motherboard.

• Long Memory Training Time: Some users may experience extended memory training times during startup. This is often a normal process for new DDR5 systems as the motherboard optimizes memory settings. Ensure your BIOS is updated to the latest version, as updates can sometimes improve boot times.
• M.2 SATA Drive Not Recognized: This motherboard primarily supports M.2 NVMe drives. M.2 SATA drives may not be compatible with all M.2 slots or may require specific configuration. Refer to the detailed motherboard manual for specific M.2 slot compatibility and configuration requirements.
• Graphics Card Not Recognized: Ensure the graphics card is fully seated in the PCIe slot and that all necessary power connectors are attached. Verify that the monitor is connected to the graphics card's output. Try reseating the card or testing it in another compatible system if possible.
• System Instability/Crashes: Check for proper component seating (RAM, CPU, GPU). Ensure adequate cooling and verify that all drivers are up-to-date. Overclocking settings should be stable; revert to default BIOS settings if instability persists.
