Like the P8H67 series, the P8P67 boards are equipped with a souped-up version of the AI Suite utility. It offers a wide assortment of tweaks all from the comfort of the Windows desktop.

EPU menu.

The EPU settings allow users to perform quick undervolt to the CPU and affect other minor system changes to save power.

"DIGI+VRM" menu.

At the opposite end of the spectrum, overclockers will appreciate "DIGI+VRM" which can change BIOS VRM settings to improve stability at higher clock speeds.

PC Probe's history recording function.

The PC Probe utility also received an upgrade with full monitoring/recording capabilities. Our only complaint is its sensor page can't be displayed outside of AI Suite, the utility has be loaded and you have to click to the right tab to check voltages and temperatures, etc.

Fan Xpert: manual user settings.

Fan Xpert has a nice graphical interface that lets users adjust the fan speed curve of the CPU fan and two Chassis fans by plotting three points on the graph.

Fan Control

The board supports control for three fans in total, with PWM-only control on the CPU fan header, and DC voltage control on a pair of Chassis fan headers. Both the settings in the BIOS and Asus' Fan Xpert utility work as prescribed, though Fan Xpert is better in that it can set a lower minimum fan speed for the Chassis fans (20% rather than 60%). The current version of SpeedFan is not compatible the two boards, only displaying temperature readings and no speed controls.

We encountered an odd problem with Asus' Fan Xpert utility in that it would always set fan control to "Disabled" the moment it loaded up with AI Suite. This resulted in the fans spinning at 100%. We spent a few hours troubleshooting this problem with different fans, various versions of the software and BIOS upgrades, but couldn't come up with a solution. Surprisingly, we did not encounter the problem when using Windows XP instead of Windows 7. We have notified Asus of this bug... but in the meantime, if you encounter this issue, we recommend just using the BIOS fan controls.
