Due to the staggering amount of voltage adjustments available, and how AI Booster seems to love automatically Overclocking my CPU on me, I've chosen to simply manually tighten down ram dividers and timings, while leaving voltages up to the motherboard, to boost as necessary. With this in mind, we're going to simply monitor the voltages as the motherboard raises them, to ensure that that it does nothing out of the ordinary. With this done, we will utilize AI booster to boost the FSB in 5 MHz hops, utilizing SuperPi to 8 Million places in between to test for stability. When instability is reached, we will boost the V-Core in the smallest steps possible, again via AI Booster. To those who wonder why this project is so A.I. Booster centric, it is due to the simple fact that the program will raise V-Core as necessary in order to account for the voltage drops caused by the processor's load increasing. For reference, our default settings are as follows:

Through a few drops of memory dividers and increases in voltage, we eventually settled upon a top speed of 3.75GHz, leveling off our FSB at a cool 1GHz. While this is unfortunately the famous "Northwood Overclock" - the simplest to do really, it's something special for a Prescott chip. To our experience, anything above this point (even a 5MHz increase of the FSB) would result in CPU temperatures slowly rising until the system locked or crashed - telling us one thing - that if we're going to go further on this project we're going to need better cooling. However, with this overclock came one issue - while voltages are set to 1.65V in the bios, they read nearing 1.7V at idle, and just 1.55V at load, showing us that this motherboard's power circuitry is definitely going to need some better cooling than a tiny passive copper sink subsisting off of superheated air. While this is indeed fine for processors at their standard speed, we're going to have to resort to either swapping the sink, active cooling it, or just placing a water block on it. Observations aside, here are our final results:
