ASUS has loaded down this board with a wide array of options that includes their WiFi-AP Solo wireless network solution, dual Gigabit LAN, ADI AD1988B HD audio codec with improved circuitry, and the complete AI Lifestyle suite. The BIOS is fairly comprehensive and is enthusiast oriented. The two most important features we used during testing are the Transaction Booster option that on average improved unbuffered memory scores and latency by 4%~7% along with the CPU Voltage Damper setting that greatly reduced Vcore droop. We noticed under load testing with our QX6700 that average Vcore droop was around .04V and with CPU Voltage Damper enabled the average VCore droop hovered around .02V.
ASUS P5K Deluxe Layout and Features

ASUS did a really nice job in the layout of this board as all features on the board except for the clear CMOS jumper are easily reached. This board features an eight-phase power regulation system and 100% use of conductive polymer aluminum capacitors that provided excellent stability during testing at stock and overclocked speeds. During our overclocking tests we found the passive heatpipe system worked well but additional airflow was required to ensure stability during overclock testing.
The board installed easily into our Cooler Master CM Stacker 830 case and cable management was very good for power, optical, and hard drives. Our only concern was that two out of six SATA connectors were partially blocked when installing an 8800 GTX. The ports could still be used with an angled SATA connector, but it seems only standard SATA cables are included in the packaging. Our larger heat sinks did fit on this board, but there was not much space left around the CPU area after installation. We will go in depth about the board and its features in our P35 roundup before Computex.
ASUS P5K3 Deluxe Layout and Features

The P5K3 Deluxe is based on the same board design as the P5K but includes a wrap around heatpipe system that provided a slight benefit during overclock testing provided airflow was adequate. We saw an average temperature reduction of about 2C when measuring the MCH under load when compared to the P5K board. However, the drawback is that installation of a large heatsink is cumbersome with this design. Our current inventory of heat sinks worked but be prepared for some minor cuts when installing them. Of course, the real news about this board is support for DDR3 memory and some interesting test results as we will see shortly.
