The Chinese overclocker yangxun8774 has posted a CPU-Z validation result that makes him the world record holder when it comes to highest FSB. He managed to tweak his E6300 to reach the extreme speed 613MHz FSB! A truly amazing feat, especially considering the fact that a lot of the extreme FSB results were made using E6600 CPU’s and engineering samples, not retail like this one. Just like OnePageBook managed to reach 5.6GHz, we believe this is as far as these CPU’s will go, at the moment. As we’ve all seen what different batches can do for CPU overclocking.
