A $20 Multimeter Might Reveal Your CPU's Overclocking Potential
Can you predict how well your CPU will overclock by probing it with a multimeter? Before you start pulling out the Fluke, let's go over the details of this story, because it's both more and less interesting than you might expect from the headline. The short version is that retro tech YouTuber Bits und Boltshas been overclocking a whole lot of Socket 370 CPUs, and he's found a startling connection between the internal resistance of Pentium III processors and how well they overclock.
Specifically, what he found was that, within a specific stepping, processors with lower resistance between the VCC and Ground pins on the CPU typically achieve higher clock rates with less voltage when overclocked. "More MHz, fewer millivolts" is exactly what you want when overclocking, so if the correlation holds up, this is actually quite the discovery, at least for retro overclockers. So does it hold...
