For KOne only (sorry it's somewhat off topic people)
I got mine to 400 * 9, but I yet to figure out what voltage to use in order to maintain the overclock (I've gone to 1.52V and I'm too scared to go higher
). I have a Thermaltake Silent Water for the CPU. As of now, with ambient room temperature at 24C, my CPU idles at 33C w/ Speedstep and C1E enabled 55C on full load. When overclocked to 333 * 9 w/ Speedstep and C1E enabled, CPU idle: 37C load: 57C.
My main problem with this ASUS P5W DH Deluxe mobo is cooling the motherboard. I have two 40 mm fans on the nb and sb and well as ASUS's fan that you clip on to the heatsink near the CPU. My case is an Antec P180B and I have 2 fans (1 exhaust to the back and 1 exhaust to the top) and the radiator/pump/fan is mounted to the front of the case. My ATI X1900XT has an Accelero X2 on it and I think this is where the motherboard is recieving the most heat.
Lastly, if you wish to talk more about overclocking, I suggest to create a new thread as to not anger other readers (one in particular, but will not mention who :twisted: )
Anyways... anyone else have an issue with the motherboard taking too long to boot into Windows?
