This is not as bad as it used to be. From compugeeks:
512MB DDR PC3200 ECC : $86.50
512MB DDR PC3200 : $65.50
For 64 bit memory ECC is as cheap as parity.
There are quite a few motherboards that 'support' ECC. See
for example,
http://www.anime.net/~goemon/linux-ecc/
Though, not all are built well enough.
Standard ECC is also called SECDED: Single bit Error
Correcting, Double bit Error Detecting. All memory errors
are pretty uncommon but of those one bit errors are the most
common.
FreeBSD *needs* to have ECC since it is already such a
reliable OS -- you don't want your uptime spoiled by a memory
failure, do you?:-)
