If you don't test your RAM, how are you sure you have no problems (unless you exclusively use ECC memory)? For example, a friend recently built a new zfs home fileserver which appeared to work fine but a zpool scrub of a large raidz pool after copying lots of files into it would consistently return one or two errors. That turned out to be marginal RAM, showed up by a long memtest86 run. Swapped the RAM and the problem went away. So RAM problems may not manifest themselves very obviously without some kind of checksumming technology (either a zfs pool or ECC on the memory itself). I have often wondered how much of Windows' poor reputation for stability is actually due to uncorrected RAM errors on cheapo PCs.
