Twelve different users on these forums resulting in failed memtest runs within a year of each other, which helped to steer them into fixing the issue that should have been “evident”… without them actually running the tests? [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12]
It takes very little time and effort to run a memtest to rule out bad RAM for a NAS server that writes and reads important data. It’s not the end of the world to run them. I even do so for my main and backup servers when I have to power them down or do an upgrade. Since I’ve already powered down, I might as well run a couple passes, in the same spirit as running extended SMART tests on my drives.
EDIT: Added yet another recent example. I hope @truenas-fan can explain the “uselessness” of memtests to us “so-called” experts who lack “deep digital systems knowledge”.
