Memtest86+ test results... advice?

  1. I was given an old desktop from a place I work because it no longer worked and it was time for them to upgrade anyways. It was easy to determine that the only problem was the HDD was corrupted. I have a new HDD I am going to install but I wanted to check the RAM, since that may have caused the corruption.

    With all 4 modules installed (2 x 1gb, 2 x 256mb), I ran Memtest 4.10. There was an error on the first pass, zero errors on the second pass. I ran Memtest on each module individually to determine the faulty stick, but all passed on at least two passes....I was hoping the faulty stick would show up.

    I reinstalled ALL sticks and have been running Memtest for the last 24 errors on 14 passes.

    Stupid me for not writing down the first error I received. I'd like to figure out if something is wrong before I go forward and start using the computer. What would you guys do in this case? If I knew what module initially caused the error, I'd automatically replace it....but I only know it was one of the four.

    In that case, I find it likely that there is nothing wrong despite the previous error.

    There can be false positives with Memtest86+; IMHO, try running a high-stress benchmark for some time and see if you get any BSODs etc.

    If you can tweak the ram settings, try to increase the speed or lower the latency's a little at a time and run memtest again after each tweak. In this way you can find the weakest chip.
    However, I somewhat agree with the others that the ram is probably ok to use as is with that few of errors.

    Thanks everyone for the replies. I let the test continue to run and I did come up with another error on pass 23:

    Tst: 6
    Pass: 23
    Failing Address: 0008c7d5234 - 2247.8MB
    Good: 00000010
    Bad: 04000010
    Err-Bits: 04000000
    Count: 1

    I did notice the "good" and "bad" were different from the original error...but that is all I remember. Is there any way I can tell what module caused the error (from this error info)? I shut the test down after 29 passes...should I just ignore these two errors I found in 32 passes?

    Other info on the system from Memtest screen...

    To know which module is responsible, the only way is to run the test on each module individually.
