  • How can I test if I have bad RAM?

    I'm starting to get some mysterious crashes and other behavior on my
    machine. I'd like to test for bad RAM. How would I go about doing
    this?

    TIA,

    Download memtest from <http://www.memtestosx.org/>. Best results if you
    start in single user mode.

    and be prepared to not have your machine for a very long time - hours (does depend on how much RAM you have).

    besides memtest, also experiment with your USB devices. Memory is
    generally the #1 cause of an unstable system, but a broken USB
    device has been know to cause similar instability problems in the
    past.

    So if the memory testing does not turn anything up, then you may
    want to try some USB experiments.

    If you have more than just a keyboard and mouse, try removing all
    the other devices, just to see if things stabilize. This would
    include removing even a USB hub.

    If you have an alternate keyboard and mouse, try using them (there
    was one case where a broken mouse was causing the problems).

    You can also have a bad hard drive. Check the SMART condition in Disk Utility.
