tally ho...
ive bought a 2500xp barton with the intent to knock it up to the equivelent of a 3200xp but ive ben mincing about on some sites and have seen that you can buy a p4 2.4C and get it upto 3.3ghz on average
if this is true and easily obtainable them im going intel but if its as hard as a coffin nail to do then ill prollys just stick with the amd i bought
i have only bought these components so far
2500xp
ti4200
i am after the following parts
xaser III v2000a
aquarius 2 water cooling system
1gb twinmos dual channel 3200 ddr
any p4 mobo which can handle the 2.4C at about 3.3ghz
..................
im hoping some people who have obtained such speeds with a p4 2.4C could get in touch as im ready to buy the parts and make the pc within days
..................
it would also be top notch if anyone could post a pretty detailed description of how to sort the memory timings out and stuff like that
cheers anyway

So basically it is VERY easy to o/c the XP2500+ primarilly because they're unlocked unlike P4's and that allows you to fine tune everything whilst keeping everything in spec. XP2500+ on average achieve XP3200+ speeds. All you need to do is drop the multiplier and select 400FSB. Then up the multiplier bit by bit (and test) until you become unstable at which point you either back off a little for the long term or try a little more voltage and go a little higher. That's it, o/c'ing can easily take < 10min and you're virtually assured optimal settings for RAM, mobo and CPU with nothing out of spec (that you don't want).
As you suspect it is not uncommon for most 2.4C and 2.6C to achieve 3.2ghz on average, some find disabling HT gets them a little higher but you're better off with it. It is a little more complicated when o/c'ing Intel as you effectively need to guess what the CPU will be able to do in order to choose your other stuff. It is better to pick better RAM as you want to keep it sync as much as possible and PC3200 isn't going to let you do that. Still since most people end up with 1000FSB+ no RAM is likely to keep synced so when you factor in a ratio to FSB PC3200 isn't really that limiting. For the mobo it's probably best to get i865PE or i875P and preferably something known to o/c well with 1000FSB+ doable. In a way o/c'ing is simple because essentially you just increase the FSB until things get unstable, then you can change the RAM ratio or timings and see if you get higher. Again when at max stable o/c either back off a little for the long term or try a little extra voltage and see if that gets you higher.
