DRAM errors: from soft to hard

[Brink]

Research (see Nightmare on DIMM street) a few years ago found that DRAM error rates were hundreds to thousands of times higher than vendors had led us believe. But what is the nature of those errors? Are they soft errors - as is commonly believed - where a stray Alpha particle flips a bit? Or are they hard errors, where a bit gets stuck?

Many errors and crashes are caused by RAM, just a fact of physical devices, they can't be made perfectly.
These can be intermittent and end up being blamed on other things. They also can cause file corruption.
These errors can be influenced by power, just happens to be the two leading causes of hardware crashes.
RAM and PSUs.
