Just because Raspian gives you faster results it does not mean the processor actually runs any faster, it is just that the instructions it does perform are more efficiently targeted towards the task.Before the Raspian release, my chips and components were getting near the temperature
Counter intuitive? As conductors heat, the molecules vibrate faster and electrons are more easily knocked loose and electrical resistance is thereby reduced. A heated conductor has lower resistance than the same conductor when cold. As the electrons in heated wire can move around more easily, it seems logical, rather than counter-intuitive, that the chip can perform faster when hot. Of course, if it heats to the point where microscopic connections come unsoldered, or insulation barriers melt and break down, then it should be expected to fail.mahjongg wrote: Tip for those interested, the hotter the device the faster it gets (which is a bit of counter intuitive, but true.). Obviously it also -ages- faster when it does.
Perfectly explained! Now I get you. And yes, I bet there's a formula somewhere that would look nice in a graph showing how hot, gets how fast, right up to the point where the heat overcomes the chip and the connections or insulation fails and everthing goes poof. Just like formula race cars! How hard can we push the engine and get the car to go as fast as possible without (quite) blowing up the engine?mahjongg wrote:Counter intuitive in the sense that overclockers desperately try to cool down the CPU of the PC they are trying to overclock, and it seems they are trying to make it much cooler than a normal system is.
But if you do know a bit more about it, it seems that these people do not exactly know what they are doing, because indeed the hotter the silicon the faster it becomes! You can even say quite exactly how much percentage points it will become quicker with each ten degrees increase in temperature.
Also increasing the switching voltage as increases the switching speed, as (parasitic) capacitors in the logic get filled up faster. Obviously increasing the voltage generates (much) more heat.
