Anyone who’s ever delved into the world of overclocking will readily tell you that this is a field where the old adage “your mileage may vary” most definitely applies. But while individual luck of the draw will vary from chip to chip, there are certain factors that influence how well a particular chip overclocks or how low of a voltage it can put up with at any particular frequency.
Component manufacturers are well aware of this, and often use factors such as transistor leakage to selectively “bin” processors according to how highly they can clock or how little voltage is required to reach a certain clock. This then allows manufacturers to get the most out of any individual unit.
All of this factory optimization isn’t to say that we as consumers can’t do a bit more optimization themselves. This is after all why we are still able to overclock and undervolt our own components. But unfortunately, we don’t often have access to the binning data of our particular components. And even if we know the PVS bin for our particular device, we rarely know how this fits into the larger overall picture with regards to other devices of the same chip.
XDA Recognized Developer HD2Owner decided to make things a bit more straightforward by creating a table and chart with all known PVS bin data for the Snapdragon 801 processor. The data is specifically for the HTC One M8 (2014) and Samsung Galaxy S5, though it may also be of use to owners of other devices powered by the 801. And with this information, users will have a rough idea of what voltages to try at certain frequencies.
