Overclocking The Casio E-125 Pocket PC

by Adrian Wong

 

 






Worth It?

As you can see, overclocking the E-125 brings about rather significant improvements in performance, especially when overclocked to 200MHz. Subjectively, applications load faster and the E-125 is even more responsive when switching between multiple tasks. IMHO, Microsoft Reader and video playback benefited most from the increase in performance.

At 180MHz, the E-125 is about 20% faster than normal. This may sound like a pittance but you will be surprised at how much more responsive the 180MHz E-125 is, especially with a full load of applications running.

The most significant performance boost, however, comes with the overclocking of the E-125's processor to 200MHz! Now, although the NEC Vr4122 is only rated up to a maximum clockspeed of 180MHz, most can actually be overclocked to 200MHz. Often, no harm comes out of such a high clockspeed. The increase in power consumption due to the higher clockspeed isn't even significant enough to worry about.

However, in some cases, the Casio E-125 may run at 200MHz without crashing but the IR port or the serial connector won't work properly. In that case, the only recourse is to reduce the clockspeed to 180MHz. But if you can overclock the E-125 to 200MHz, expect it to really fly! On the average, the 200MHz Casio E-125 is now 33% faster!

Therefore, if you have to choose between the Compaq iPAQ and the Casio E-125, the possibility of an overclocked E-125 will definitely make it more attractive than it would normally appear. Of course, the iPAQ can also be overclocked and the procedure is so much easier. But now, there's finally a possibility of owning a Casio E-125 that is about as fast as the Compaq iPAQ! Imagine - the Casio's feature-rich and problem-free design and its fantastic HAST touch screen with iPAQ-equivalent performance! For more information on the Casio E-125's overclocked performance in comparison with other Pocket PCs, take a look at the Pocket PC Performance Comparison!

Now, if you think overclocking the E-125 is something you want to do, continue reading. But remember that we won't be held responsible for any damage to your E-125 as a result of following the steps outlined in this article. 

      

       

Tools Needed

Here's a list of items you will need to perform the "operation" :-

  • one small-sized screwdriver with a Philips/cross head (top)
  • one medium-sized screwdriver with a Philips/cross head (bottom)
  • pencil (not shown)

As you can see, you don't need any fancy tools. But if you can get hold of one, a pair of surgical forceps or pliers would also be useful as well.
