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?:-)
