    A chip is a chip, right? Not by a long shot. There is a huge difference between one processor and the next. Anyone with experience in IT knows that, even some newbies know that. But the question is...why?

    Most people don't realize microchip manufacturers don't set out to create chips that run at a certain speed, per se, but instead crank out huge batches of chips, then test each batch (with quality control samples) to see what the average, stable speed for the batch is. Whatever number they decide on is what that batch is labeled as, in spite of the fact that some may run slower, and some are faster. This is why overclocking is even possible at all.

    What is it that makes for such a discrepancy? If you think about what chips are made of (silicon) and where that comes from (sand), it starts to make a little more sense. Nothing in nature is consistent, including sand. Sand comes from ground up rock. Different kind of rock equals different kind of sand. If a batch of sand being used for silicon manufacturing has a high amount of impurities (say iron, or carbon) these will cause very tiny changes in the end product. So, we take random sand, make silicon out of it...now what? The silicon is made into wafers then printed (yes, printed) with the millions of transistors that turn it into a processor. Variations in the silicon do happen, and when a variation happens in a spot where a transistor is...well, that is what gives some devices distinctive quirks.

    So, the OV has a "600" but most seem to be able to run in the mid 700's, and some even higher. We can't say for certain what the OV should be clocked at because each one is an individual. Trial and error is the only way to determine your phones capacities.
