Note that this was achieve with standard air cooling, though we had to boost the NB Voltage to 1.55V beyond 480MHz. Pushing the limits of a Core 2 Duo E6300 and DDR2-800 memory, we managed to push the P5K Deluxe up to a maximum stable overclock of 490MHz. Nevertheless, the P5K Deluxe proved to be an exceptional overclocking motherboard when put to the test. Surprisingly however, we find that the MSI P35 Platinum actually has a better overclocking BIOS in terms of higher voltage selections and better granularity in most options. Looking at the BIOS itself, ASUS seems pretty ambitious with a maximum FSB of 800MHz (3200MHz QDR) selectable. Basically, it just means that the board supports a DDR2-1066 divider natively and has more timing options available. ASUS is hyping a new technology called Super Memspeed Technology that 'Enhances Memory Speed up to 75%', if you believe what's on the box that is. The P5K Deluxe is ASUS' flagship DDR2 motherboard for the P35 chipset, so it comes as no surprise that it is geared for overclocking. Multiplier Selection: Yes (unlocked CPUs only).NB Voltage Settings: 1.25V to 1.70V (in 0.15V steps).FSB Termination Voltage Settings: 1.20V to 1.50V (in 0.10V steps).CPU PLL Voltage Settings: 1.50V to 1.80V (in 0.10V steps).Memory Voltage Settings: 1.80V to 2.55V (in 0.10V steps).
