I feel much more skeptical about your belief in the complete and eternal reliability of modern electronics
ever heard about CPU wear effect?
In any case, no one can cheat a crash dump. Whatever is there, is the ultimate truth. And when the operating system fails at the most basic low level operation of copying a block of memory, physical RAM is naturally the first thing to suspect. Although of course, things like power glitch, CPU or motherboard's memory controller issue and such are also a possibility.
