RAM test?

Discussion in 'Sun Hardware' started by Paul Foerster, Jul 13, 2003.

  1. Hi,

    .... I received the new 2G RAM for my Blade 150 yesterday and put it in
    the machine. The machine comes up fine reporting 2048M of RAM. I just
    want to make sure it's really ok and wondered if there's a way to check
    it, a piece of RAM test software like "memtest86" for Linux or something
    like that.

    I'd be glad if someone can point me to such a thing. Thanks very much in
    advance.

    There is SUNvts to test a machine. It is downloadable from Sun's site.

  4. Just a word of causion. SunVTS refuses to run on my system (U80)
    running Solaris 9. Whether this specically effects the U80 or not I
    don't know, but I can't get it to run. Someone has pointed out to me
    there is a patch for SunVTS, but that patch is not downloadable
    without a contract. Hence I've been unable to obtain the patch, so
    can't run SunVTS. When I had memory problems, I wanted to run it.

    You should also check any messages in /var/adm/messages. You can see I
    had a problem during on U3004 during April, which was solved by
    Dataram replacing the DIMM.

    Hello David,

    I guess you are out of luck with your U80, SunVTS runs fine on my old
    SS20 under Sol9.
    You'd better give it to me, I will run Linux on it ! ;-)

    Word has it that this problem will be fixed very shortly, and that the
    patch required will be available without a contract within the next week
    or two...

  7. It's worth looking at /var/adm/messages too. As you can see, I had a
    problem back in April, which thankfully was fixed by replacing a
    couple of DIMMs. Over 3 months now since I had a corrected memory
    error, so given Sun say about 3/day is acceptable, I think I'm okay.
    You can see I did get as many as 1508 errors in one day, but the
    system still worked okay.

    SunVTS is another option. However, I can't get that to work under
    Solaris 9 and since I don't have a support contract, I can't download
    the required patch. It's possible it might be fixed if I used a later
    version of Solaris, but I can't be bothered to mess about doing that.
