The problem I am having now is that I can't even run it at the _rated_ clock
speed. I have to run it my 2500+ as a 1900+ to keep it from locking up.
I adjusted the the "FSB Frequency" down from 166 MHz to 133 MHz. I usually
get temps of 48-52 C after a few hours of normal use (running as a 1900+).
If I do anything CPU intensive (compile a kernel, zip or unzip a huge file,
etc.) then it hot enough that I can't even think of running it as a 2500+
and as a 1900+ the temps go to 53-57 C. That seems a bit high to me.
