For a whole day did it take to figure out that this memory is not running at the nanoscale AQ01. Memtest showed numerous errors, which made me only in faith, the memory is faulty. The incorporation into a HP ProBook 6050b revealed that my guess was a misdiagnosis. There he runs without problems and Memtest displays it as properly.
It is quite possible that the memory in other systems is going well. However, I give only one star because it has cost me a day.
