My mac pro is showing in the hardware-selftest a failure with memory,

Hallo Community,

after starting my mac Pro 3,1 , the (self-testing) hardware-test is showing a failure, although the machine is running quite normal. Inside there are 6 memory -blocs. When looking into the deatailed test, the DIMMS are all ok.

Here the original german message:

Selbsttest beim Einschalten:

Zuletzt ausgeführt: 08.03.18, 10:50

Ergebnis: Fehlgeschlagen

Fehlerart: Speicher

Speichersteckplatz: 140371258646535/140371258646542

For testing purpose I changed the four discs against a clean and simple running system with Os X 10.11.6 but the same result.

I would be very happy, if somebody could give me an advice!

Thank you very much in advance,

Hallo,

now I can give the answer myself.

I checked each DIMM in single pairs by starting the machine again and again. At the end one DIMM showed a failure. After having installed the DIMMs following the official plan, my MacPro is running now without a problem.

Thanks for reading...Everything is ok. now!
