I see quite a few posts about overclocking. It's inevitable that hobbyists (as against production engineers) will resort to all sorts of unreproducible tweaks to get their projects working faster.
It's interesting that some datasheets show a 'stepped' speed/voltage SOAR and others a linear relationship (presumably more realistic, though I expect in reality its not a straight line at all). I'm just musing on what the limiting factors might be:
- Reliability of eeprom writes
General clock errors causing random errors
Clock errors to specific modules (which ones?)
Memory/register read/write errors
Power dissipation problems (i.e. at high clock speeds and low voltages gates spend too high a percentage of their time in the 'crossover state' between 0 and 1)
Failure of one or more clock sources to start/maintain
There are surely other issues; my money would be on the first or last of these. What do the panel think, as if there is a likely failure mode for overclocked chips, perhaps it could be specifically tested for or worked round?
