The P5Q Deluxe has all the important BIOS settings for achieving a top overclock, with a broad enough range of voltages to please the majority of fanatics. A CPU core limit of 2.10 volts for example isn’t as high as that of the Maximus II Formula, but it’s still enough to fry most cores. Asus requires a jumper change to remove a 1.70 volt core limit, and for good reason.
The AI Tweaker menu begins with Asus’ familiar “Ai Overclock Tuner” automatic overclock setting, followed by manual controls for bus speeds, memory ratios and timings.
Several advanced memory timings can also be adjusted, but most users will get the best results by simply choosing “Auto”.
All of the most important voltage levels are adjustable, but unlike the Maximus II Formula, the P5Q Deluxe can only adjust GTL Reference Voltage in pairs.
A complete set of BIOS values can be stored as a user profile, making it easy to restore everything to a previous value should an experimental overclock force a BIOS reset. Profiles can also be exported to a USB flash drive.
