Athlon XP CPU temps... 50C is NOT high!

Physically impossible. You would see a continually rising increase in temperature if your processor was generating more heat than your fan was able to remove from the heatsink, but it can't be exponential. Violates the laws of nature.

how do you figure? anything above 2.2ghz is out of spec and its probably a boost in the voltage in order to do it, hence the huge jump.

The context in which you use exponential appears to be as a power which would for example indicate 50 celsius times itself and that's just not the case so either you are misusing the word or we've somehow misinterpreted what you've wrote.

your right
it must have been power usage.

I don't think that would be it either... the only thing I can see increasing exponentially is current leakage as voltage increases.

it said thermal output,i asumed it meant heat but wattage sounds more correct. and just because its exponetial doesn't mean it has to be multiplied by itself, fractional values can yield well rounded curves.

Well, with the examples you give, you have too many variables... heatsinks, fans, voltages, core speeds, FSB speeds... you have to have more controls in an experiment and only one variable to come up with a logical/valid conclusion... otherwise it's useless cause the results aren't reproduceable because you have so many variables it's almost impossible to get every one the same every time. As soon as you give the CPU more voltage, all the manufacturer's specifications mean nothing, because they're all based on the processor at it's default voltage. If you increase the voltage, the curren draw spec is wrong, the wattage spec is even more wrong, the cooling requirements are different, the power supply's "AMD Approved" rating means nothing... it's endless.

What I'm talking about in the original post is when I see people list their temp as 50 degrees C, and somebody tells them that's too high, and that's the source of their instability and they should look into a better cooling solution. 95% of the time, that's bad advice. There are a few exceptions where 5 degrees C might make the difference between being stable at 2.52 Ghz or only 2.48 Ghz. Even then, it's not worth fussing over because as the room temperature changes, the case temp will rise, and so will the CPU temp, which might make 2.48 Ghz unstable. It would be better to settle for say, 2.45 that's totally stable up to 65 degrees than 2.52 that's only stable up to 50 degrees.

The kids are begging to be dropped off at the pool so I apologize if my last few thoughts were a bit unorganized, I'm a little distracted right now, lol.

I completely agree with everything you said, the variables drive me nuts, I ended up giving up and settling on 2.4ghz with stock FSB and timings, one thing would cause another to go wrong, or the cpu would be unstable, or the pci latency would get messed up(even with the lock!), or the heat would be too much. Anyhow, the chart I saw was from a respectable site otherwise I would have ignored it(I think it was Club OC), hence it had to be a reasonable benchmark conducted under a set circumstance. Despite this I really don't have much else to offer to this thread considering I?m merely going off of memory and have no proof or backing to give in return. Sorry for wasting everyone's time :\
