The Candidate: Core 2 Duo E6300

500 MHz FSB? Core 2 Duo Overtakes Core 2 Extreme
By

Only three months ago, we overclocked a Core 2 Duo E6400 from 2.13 GHz to 3.33 GHz by raising the FSB speed from 266 MHz to 415 MHz. Tom Soderstrom increased the core voltage to 1.5 V to make the system run reliably ; more system clock speed would have been possible, but the processor hit its limits.

Using the Core 2 Duo E6300 instead of the E6400 saves you $30, and we also recommend sticking with the default cooler that comes with the CPU. In our E6400 overclocking project we used a liquid cooling solution to provide maximum cooling for the processor, but the E6300 that we bought proved to be an even better overclocker, and doesn’t require sophisticated cooling measures. The answer likely lies in the processor stepping : the E6400 sample was an F5 stepping, while the current versions are F6.
