I have Pentium 4 3.0Ghz and I change the frequency from 200 (standard) to 217 where the ratio is 15. So I have 3.25Ghz. I boot up my pc and I can see the different. It is a bit faster than before, my programs opened more quickly,and I ran Windows 7 WEI, it goes from 4.1 (3.0Ghz) to 4.5 (3.25Ghz). But in my computer Properties, it still show 3.0Ghz. CPU-Z show 3.25Ghz. How to overclock it permanently? Where we open computer Properties, and it will appear 3.25Ghz?
