Overclocking and Under Volting the Pentium M
!!!!! This is not a definitive guide to overclocking, it is MY quick and dirty way to get a fast overclock. This guide will not maximize your performance, it will only enhance it. If you want to find the maximum performance read some of the stickies. As usual I and the owners of the forums take no responsibility if you damage your stuff. You break it you bought it. Use your brain when overclocking keep an eye on temperatures and don't use unreasonable voltages, you can damage your equipment if you don't. This guide is a living document I will update it as corrections are made and new techniques are adapted. Please do not post flames, keep it to constructive information or questions regarding this guide. !!!!!
Several people have been using this form to find out about building their own laptops. With this comes the desire to overclock and under volt the Pentium m. This is a quick guide to doing just that.
For those who have a laptop based on the 915 chip set and have a 400mhz FSB processor there is a simple wire modification that will force your processor to run at 533. I do not recommend getting a processor with over a 17 multiplier as there is not guarantee that it will boot. So your best options are the 735 which should do 2.26ghz and the 725 which should do 2.13ghz.
The first thing your going to need to do is make the wire for this mod. I use a single strand from some braided speaker wire. Cut it to a length of about 4-5mm. Then bend it into a U shape from the middle of the wire. I find that the best way to insert the wire is using a small pair of needle nose pliers.
Now that you have the wire insert it into the two holes indicated in the picture. As you can see I have already placed my wire in the correct place to assist you in finding it on your laptop. Now pop your Pentium M into its socket and lets boot the sucker.
Now that you have it modded to run at 533FSB your laptop is going to use allot more battery power. That's where the undervolting comes in. Download .NET and Centreno Hardware Control (CHC). This program lets you set up voltages and multipliers. I use dynamic switching so that as the computer requires more power it simple uses one of my preset multipliers and voltages.
To test use prime95 set it to torture test large FFT and let it run at the default voltage for a while, then using CHC reduce the voltage, again let prime95 run until you feel satisfied that it is stable. Repeat this process until you find the LOWEST stable voltage at your maximum multiplier and then drop the multiplier to a lower number. Repeat again testing with prime95 until you find the LOWEST stable voltage for each of the multipliers you wish to use.
That's it folks your done, now not only are you getting a top of the line CPU for pennies on the dollar, but your also getting the most battery life you can out of your new powerhouse of a laptop.

sorry to bring this post up years ago...
Ok i think it didnt work. i looked at different forums about overclocking pentium m. but the result came all out the same. My Asus A6vm with 735 still getting 1700mhz read off the bios and cpuz. I also did volt modd earlier but there is no point
here my config
PIN MODDED: @attach1
ORIGINAL: @attach2
i knowtice there is a little switch, is that the one? (red ring)
If yes what is 133bus is? 1off2on? or 1on2off?
EDIT:
Problem solved with the switch> 1off2on ,now its running 2260 mhz!!

Yeah, I have tried it. It works so well with CT-479.Kinemaster Diamond
