Built to work - what more could you want?

Due to the partly negative reviews I was critical and wrongly - immediately installed correctly recognized by the computer Siemens - speed test - everything top. Works seamlessly - what more could you want? Confused, I was something that the board only has half the height as the other built-in memory - but then does the function and not diminish my fear that the chip is not properly in the holder locks has also not materialized. Just as a reference - the height of the supplied Memory strip does not correspond to the "normal" size.
