Now on to our next increase in speed. Restart the computer and get back into your BIOS and Advanced Chipset Features. Follow the same procedure as above, only this time you might want to push the increment down a little bit. I chose to use 5MHz again because that just happens to be my style, living on the edge and all. Do the same with your RAM. Again you will note that my BIOS does not afford me the option to overclock my RAM, which is why there is no representation of the RAM being overclocked on the BIOS screen in the pictures. Also, in my experience, it is around the 10MHz FSB increase that you might start to notice a temperature change for an operating processor. It is also about the time where you may or may not be able to get the processor to boot into the operating system.

After saving my settings, and restarting, I was pleased to hear that lovely Windows login sound once again. Just as it was last time, it is important to test the processor at this new clock speed, as I did while playing some Counter-Strike: Source. The processor reached a peak temperature of about 50C, which is normally what it gets to under such conditions when at stock, so no cause for concern. However, I noticed the idle temperature was 1C higher than it was before. With this in mind, I took another snapshot of my CPU-Z readout, and got ready for another increase.
As you can see in the picture, so far we've increased the clock speed of my processor by about 220MHz, only 80MHz or so more to go. You'll also notice from the readout that the FSB is shown to be 215MHz. This is logical when taking into consideration the increment scaling that I mentioned before. Basically this means that although I have only used 2 increments of 5MHz, in reality it has been slightly more weighted than that, and I have actually increased the FSB by a full 15MHz, rather than 10MHz.

Back into the BIOS for our third (and hopefully last) FSB increase to get us to our 3.30GHz goal. This time it would be really wise to decrease the increment in order to get a better perception for the limits of the processor. And yet, I of course chose to increase the FSB by another 5MHz. So, whatever increment you chose for this increase, make sure you do the same for your RAM, and save settings to CMOS and exit the BIOS.

This time I had some problems. When my computer started back up, it would almost get into windows, but then it would restart. This process would cycle over and over again if I had allowed it to. So now your computer won't start up correctly, what are you going to do? Don't panic, there is always a solution! Get back into your BIOS to make some new adjustments. This is the first time we are going to raise the vcore (CPU voltage) so that there is more power going to the processor for it to be able to operate at these new higher clock speeds. Depending on your BIOS, you should be able to increase of decrease voltage by some pretty small increments. In my case, it is .0125V, so I will add one increment on to my stock voltage of 1.5V, giving me a total vcore of 1.5125V. So, we save these settings and restart the computer again, only to be greeted by the same results: the computer almost gets into windows, but not quite. So, the only thing to do is repeat the process, raise the vcore by another .0125V, so your total vcore is now at 1.5250V. Again, after saving the settings and restarting, the computer still won't get me all the way into windows.
