    Hello everybody, we just bought two pairs of Kingston 2 GB (2x1GB) DDR2 800 (PC2 6400) ECC Fully Buffered (FB) Dual Channel Kt Memory for our :apple:MacPro:apple:.
    After installing it crashed when it reached some considerable amount of work. We run the Apple Hardware Test (v3A146) and it found this error:

    4MEM/5/40000006:B:O:C:O:R: D (this last space before D was intentional due to ": D" without space is a smilie --> :D)

    I google it without great results (just similar ones).
    Does anybody know what does it mean?:confused:

    Just call Kingston, get some new RAM. unless you're SURE which stick is bad, replace all 4.
