How about an xp2800+?? I'm 23 hours away to winning it on ebay but I'm still undecided to buy it because of its 12.5 multiplier which made me think that it would be harder for me to get it running at 200 fsb.

Questions:

Looking at the thermal specifications of athlon xp processor, it appears that it has a max theoretical thermal power of 68.3W compared to 76.8W of 3200+. What does this mean anyway? Why is does 3200 has a higher thermal power and what are its implications? Same as with the maximum current.

Does raising the fsb also increases the cpu temperature even without raising the core voltage?

Is there a use to still overclock it further (increase the fsb or clockspeed) when I already reached the 400 fsb 1:1 ratio?

Don't get bogged down in the specifications of the two CPUs; what really matters is that high locked multiplier. More than one person has pointed out in your other post, 12.5 is going to be difficult to run at FSB 200. I know you're in a bind because you want to find a good CPU but the odds are more in your favor if you find one with 11x or 11.5x.

No matter what the advertised wattage or amperage, most XP2800+s would have no problem running at the XP3200+'s 11x200 - IF YOU COULD CHANGE THE MULTIPLIER FROM 12.5 TO 11.

If I remember correctly from a couple of years ago, increasing the FSB from 166 to 200 to overclock an XP2500+ didn't raise the CPU temp very much. I think it went up a couple of degrees. But I did have to increase vCore to make the overclock stable and that added a few more degrees.

Good luck!
