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,
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

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?:-)
