I vaguely recall looking at overclocking pictures for the EM-500, around 2001 when I was considering (but didn't do it) over-clocking my EG-800. Don't have any saved pictures, sorry. But it involved rubbing a soft pencil between two solder points or trace ends somewhere near-ish to the CPU, no idea which ones exactly. Called 'clocking pins' or something, and I think there were three sets of two pins together... and maybe it was connecting the middle set together?

All I can find with Google images are nice instructions on the very complicated disassembly of an E-115 and then the rather simple graphite pencil overclock once inside. The EM-500 link on that site is dead, thanks to GeoCities being dead. But I heard about a project to archive Geocities sites before the shutdown, so maybe that's out there somewhere and is searchable, or not.

I never handled an EM-500, much less owned one or took one apart. So no clue, sorry. Perhaps there's someone out there who did the mod and can remember... and maybe they'll run across this post some day. Good luck.

Hi,
Back in the day I tried this and it worked. The original article has been pulled from Brighthand. However I did find it on the Internet Archive.

http://web.archive.org/web/20010619015958/www.brighthand.com/html/howto/overclock4.html

It has pictures of which jumpers to connect.

BTW there was a link to the original article on Pocket PC FAQ - http://www.pocketpcfaq.com/wce/overclocking.htm

It is rather blurred and small. Guess you'd have to try connecting various points in the area of the blue line... but that seems risky for your device. I've no idea why the author of that picture would have been so vague, seemingly not pointing at any particular points with the 196 - 204MHz part of the illustration. Seems likely either he was as bad with MS Paint as he was at taking photographs, or that there used to be a large version of the image with clearer instructions and that is now lost. I'm guessing the former, as the photos really are terrible.

Hi,
The circles that are in different colors show the areas that configure the clock speed depending on what you want.

The article refers to using a pencil to close the jumper viewed in GREEN. This brings the CPU speed up to 180 MHz.

That's as fast as I was able to make mine work.
