Asus P5K P35 Socket 775 Motherboard

As with all of Asus' most recent motherboards, the P5K is based around a BIOS from Phoenix Technologies. Some enthusiasts tend to favor the Award BIOS layout over Phoenix, but it's extremely hard to find fault with the overall layout and wealth of features available on the P5K.
Voltage options are equally as flexible, with vcore available in 0.0125v increments from 1.000v all the way up to 1.700v and vdimm ranging from 1.80v to 2.55v in 0.05v steps. More information on the voltage and overclocking options can be seen in the table below:
|CPU PLL Voltage||1.50-1.80v|
As you can see from above, the P5K actually managed to beat the maximum overclock we'd previously set using the E4300 chip on the P5B Premium board by ~50mhz (5mhz FSB). This certainly shows that the P35 Northbridge can offer the same (if not better) overclock potential as its predecessor the P965.
Dropping the multiplier down to 6x and increasing the Northbridge voltage to it's maximum of 1.70v allowed for some serious FSB speeds, with the P5K hitting a very impressive 520mhz. This is 40mhz higher than the maximum FSB obtainable on our P5B Premium board, and should certainly keep the overclocking crowd happy.
