I know exactly what it does and how it works etc, so don't worry it's not that sort of question 
But what is the point of it?
Or perhaps a better question would be: "What is wrong with non-ECC memory in servers?"
Surely if you have a system with non-ECC memory and all of a sudden it BSODs due to memory corruption then that is clearly a serious hardware fault (or maybe BIOS configuration i.e. overclocking too high!)
It seems to me like ECC memory was designed for a bygone era where electronics were far more sensitive to EFI. I can UNDERSTAND why like the Mars Rovers, space probes and orbital satellites surely have ECC memory. But why a run-of-the-mill server on an Earthly data center?
