Interesting experience with p4 voltage as set on Antec pot

I am trying to perfect my system to be 'by the (cics) book' (thanks to Gregg for this suggestion). I have added 2.5" lap top drive, a fanless cooler on order etc etc and all things have improved sq and system stability. I also have tried different voltage levels on p4 by adjusting the Antec onboard potentiometer. For many months I had it set all the way counterclockwise which gave me 11.82 volts (as measured by my vom on the p4 cap mod board--more easy to get at and definitely more accurate than cpuz). Anyway I tried adjusting the pot and with cplay 2.0b 22 the mere adjustment of a few tenths of a volt is not subtle from a sq perspective. Too high and the highs dry up and it sounds bland. Too low and it sounds wimpy. So I found that 11.94 was perfect for my system--good dynamics/bass and almost perfect highs--very ambient/airy with great attack/release and zero hardness.

Now the sweet spot may vary for everybody but I am running juli@ analogue outs and I currently have my host clock control at 165 and vid (as shown in cpuz) at .83 volts. I was very surprised at the sensitivity of my system's sq to this p4 voltage setting. If you try this re-check bios because it kept resetting host clock control to auto and mememory multiplier to auto when I did the experimenting. But if you stick with it and get your 'normal bios settings' back, the sound will change a lot.
