Yes! Most Palms can run twice faster than their default speed.
THERE IS NO WAY THAT YOUR PALM CAN OVERHEAT WHEN YOU OVERCLOCK IT. The processor
in the Palm consumes so little power that it simply cannot happen, even at the
highest speeds.
So you cannot damage your Palm by overclocking it. And in order to overclock you
do not even have to open your Palm. It can be done with a software utility
called "AfterBurner" (version 3.1 or higher, you can find it at PalmGear:
http://www.palmgear.com).
Before you try to overclock, you should perform a HotSync operation, so your
data is safely backuped into your PC/Mac.
Overclocking too much can in some cases hang your Palm and erase its data.
Actually when you experiment with overclocking that's exactly what you want to
do in order to know the upper limit your Palm can stand.
When you have found this upper limit, press on the reset button that is at the
back of your Palm with a pin. If your data has been erased, just HotSync again
and everything will be put back into place.
Reinstall the overclocking program if necessary, and set it to the highest speed
that did not hang your Palm.
You are done!

No absolute limit. As stated above, you should try it by yourself and see at
what speed it hangs. If it ever hangs... My m505 runs at 54MHz (the highest
speed you can set with AfterBurner 3.1) and never crashed.
>Has anyone had any problems with overclocking?
The only problem if that if you overclock too much (without crashing the Palm)
the internal clock could be off.
That means that you should decrease the speed (actually your Palm will run as
fast, what's off in this case is the time adjustement system).
How to do that?
1) overclock your Palm as explained above with AfterBurner 3.1 or above (very
good overclocking program). Note that AfterBurner is free for speeds up to
37MHz. If your Palm can go higher, you have to buy the registered version of
AfterBurner ($9). It will allow you to try frequencies of up to 54MHz.
2) Download Chess Tiger from http://www.chesstiger.com ("Download" link).
Install it on your Palm (it will be in demo mode until you actually pay for it,
but for the experiment we want to do it does not matter).
3) Start Chess Tiger and play the first move of a new game (this will start the
players clocks). Compare Chess Tiger's clock with a REAL clock.
4) If Chess Tiger's clock run too slowly, you have to decrease the frequency
with AfterBurner and go back to step 3.
When you have finished this procedure, your Palm is OPTIMALLY overclocked!

Chess Tiger for Palm is estimated to be 100 elo points stronger than Chess
Genius. Go to http://www.chesstiger.com and follow the "FAQ" link. In the FAQ
page look at the question "How do you know that Chess Tiger is strongest program
for the Palm?".
