How to Overclock an Intel Pentium G3258 Guide:

System Setup:

For this guide I used the following parts. Please be aware these are not the only parts that will work and the stock Intel cooler will be sufficient enough for a mild overclock. Quite frankly, the Noctua cooler is extreme overkill and was only used because I had it laying around.

Setup:

Final BIOS Settings 4.0GHz:

Reaching 4.0GHz should not be a problem at all! Some current chips do take a little more voltage, up to 1.2v, to reach it at these settings and my BIOS settings below is only a guide to what you may have to apply in order to reach the same as me. The Pentium G3258 for the most part does not need anything more than its stock cooler and stock voltage to reach a stable 4.0GHz  overclock.

Final BIOS Settings 4.5GHz:

I was able to reach 4.5GHz with only minor tweaks and was able to run Prime95. Around 4.3GHz the CPU decided it did not want to run with 1.1v on the vcore. Once you approach 4.5GHz, many of the voltages will have to be adjusted and tweaked. At 4.5GHz is when CPU Ring Ratio may need to be raised along with the voltage. I, however, was not able to pass 45 Ring Ratio within the safe voltage limits. Finally, do not forget about the Agent voltage! That one is completely dependent on a few different things, like speed of the memory, density (4 or 8GB modules), and slots used (1, 2, or 4). I was using 2133 X.M.P Profile, which is why I had to raise the voltage.

Final BIOS Settings 4.7GHz:

To reach 4.7GHz was a cinch once I adjusted all the smaller voltage settings. Like all overclockers, it was a journey with many failures along the way. One day it would boot and run Prime95, and the next time Windows would not load. It took a while to sort it out by backing down to 4.5GHz and raising each setting until I settled on the below settings. Then I raised it until it would not go any higher with the set voltage I felt safe with. Even so, the CPU with 1.4v would not pass 4.7GHz.. I consider this the chip's hard limit, which is a staggering 1.5GHz overclock! Since 1.3v is a little high for my tastes, I can lower the voltage slightly and settle with 4.6GHz just fine.

CPU Voltage
