So I was given an Intel DG41TY motherboard with a Core 2 Duo E7500, 2.9 GHz.
I wanted to OC the board a bit. Looking around, none of the direct FSB mod programs supported my clock generator.
Fuck it - we're bit-banging this motherfucker MANUALLY WITH A PIEZOELECTRIC LIGHTER IGNITOR.
Grab datasheets, start checking for how this thing interprets signals. Cool, now I know how this clock generator works, and how I need to feed electricity to it to generate my desired clock speed for the FSB. Solder on a couple of diodes for the voltage drop, add on a resistor. Attach to the appropriate pin. CLICK THE PIEZO. Watch the FSB ramp up 300 MHz and immediately lock the computer. Okay, math was off, let's re-figure what I... OH! Read the resistor value wrong! Derp. Okay proper resistor is on. Try again. Oooh! 1 MHz incrementation, PERFECT! Test... Test... Test....
Okay, CPU-Z is smoking crack. 15 GHz? I FUCKING WISH!
In the end, I got CPU-Z to report the real OC - 3.3GHz stable, zero voltage adjustments.
Just because the software to do it doesn't exist doesn't mean it can't be done another way.
