Basic Overclocking Guide for Intel C2D Processors

Basic BIOS Settings

Basic BIOS Settings

There are a few areas that we need to change a few options in that will allow us a higher stable overclock. You can do these in any order that you please.

BIOS Advanced Features

The first thing we need to do is disable the Core 2 Duo's advanced CPU features. On my board this area is found under "Advanced BIOS Features > CPU Feature". Once in this menu you will find 3 key items that should be DISABLED: Limit CPUID MaxVal, C1E Function, and EIST Function. The other two options in between are undecided whether or not they make a difference to the overclocking abilities of this CPU. By default these settings are enabled, I have disabled both of mine. Disregard the Thermal Management setting.

BIOS CPU Features

That's it for the basic settings. Changing these few options will greatly increase your maximum overclock potential. Next we will look at some RAM timings and discuss what might work best for your setup.
