ECC (in the strict sense) has never been ubiquitous.
At one time every computer I interfaced with had ECC. It was very
popular with me and everyone else I knew. :-)
Parity was quite common in certain timeframes, but parity won't stop your
system crashing if you get bitflips - it'll just make it crash
*immediately*.
Parity would at least provide for better error messages and
diagnosibility. I just tossed out a bad one year old 4G 204 pin ram
just TODAY that caused really wierd errors on the system. I pulled it
and ran memtest86 on it in another system and it threw errors on an
overnight run fortunately confirming the problem.
