ASUS P5Q Deluxe User Manual

To update the BIOS, download the latest BIOS file from the ASUS support website. Use the ASUS EZ Flash 2 utility in the BIOS setup to select and update the BIOS file from a USB flash drive. Ensure the power supply is stable during the update process.
Ensure the RAM sticks are properly seated in the DIMM slots. Check the motherboard manual to ensure the RAM is compatible. Try using different slots or testing with known good RAM to isolate the issue.
Enter the BIOS setup by pressing DEL during boot. Navigate to the 'Ai Tweaker' section and adjust the CPU and memory settings. It is recommended to increase values incrementally and test stability using stress-testing software.
The ASUS P5Q Deluxe motherboard supports up to 16GB of DDR2 RAM across four DIMM slots, with a maximum of 4GB per slot.
Check all power connections and ensure the CPU and RAM are properly installed. Clear the CMOS by removing the battery or using the jumper. Disconnect all peripherals except the keyboard, and try booting with a minimal hardware configuration.
The P5Q Deluxe supports SATA II (3Gb/s). SATA III SSDs (6Gb/s) can be used but will be limited to SATA II speeds unless a compatible SATA III expansion card is installed.
Enter the BIOS and navigate to the 'Advanced' menu. Set the SATA configuration to RAID mode. Save and exit, then use the RAID setup utility during boot (Ctrl + I) to configure your RAID array.
A power supply with a minimum of 400W is recommended, depending on your system's overall power consumption. Ensure it has the necessary ATX 24-pin and 8-pin 12V connectors.
Ensure all case fans are functioning and consider adding additional fans. Use a high-quality CPU cooler and ensure thermal paste is applied correctly. Maintain good cable management to improve airflow.
