I don't see anything from those quotes that disagrees with anything I have posted. Nice to see that they have done a good amount of bench testing. One thing I will add to their testing is more than likely they have not drilled down through the package and measured temps a specific PN junctions. That is something you do in the semiconductor industry testing but is almost never done outside of the manufacturer. The over voltage causes temperatures to rise at specific locations resulting in eventual junction failure. I would have to acid etch the package and use an scanning tunneling microscope to tell you the exact failure but almost always it is heat related in these cases. In the past I have performed a lot of this kind of work. I proved we had an ESD problem when the design engineers insisted it was not possible. X company was changing the geometry on X company's ESD structure that rendered the structure non-functional. Anyhow getting back to this topic, the over voltage is more than likely causing transistors to heat up one way or another. If voltage was causing noise, a short, or race condition you would see that pretty quick in my experience. Of course YMMV.shalo wrote:But you cannot stress test a raspberry pi without stress testing a raspberry pi. You're in an overclocking thread so it is a given that people here and interested in overclocking and you are saying not to stress test the raspberry pi.FX4 wrote:Short answer, because I used to do this. Random sample of boards, crank up the clock, crank up the the voltage. Wait for them to fail. Document the failure points and then look for trends. It is a lot more complicated than this but a high level it is how destructive testing performed.
You are likely to cause yourself way more problems running an unstable pi than ensuring it is stable. When it crashes say once every couple of weeks, you will have a nightmare trying to narrow down exactly what the cause was and of course, the crash might just be inconvenient.
The people who designed and work with these very chips on a daily basis are telling you that heat is basically not an issue, if they can't then I obviously can't convince you otherwise
I'm genuinely not sure I understand what point you are trying to convey other than you worked in a related field 15 years ago back when the first 3D gpus were only just becoming mainstream. I don't think overclocking is for you and that's fine too.
