Mission Impossible?

Works flawlessly in a Dell Studio 1535. Buy from Amazon market place at the dealer "Diewald Memory".

But unfortunately worked only at the third attempt:

In the first attempt was not shown the bolt brand "Dolphin", but that the manufacturer "CSX" were sent. Does not really matter, should work yes. Unfortunately, only one of the two bars was detected. After feedback in Diewald memory and the corresponding tests, I was immediately another memory module, but not of "CSX" but by the manufacturer "Samsung" sent. Asymmetrical Configuration with dual channel RAM? Hm - let's say "unconventional". But why not, because with a bit of luck it haut yes actually go well with mixed modules; sees halt only after Bastelbude. But this tie was not recognized after installation, so I had to make do not worry about the memory configuration. Third time I received two new memory modules, precisely the "Dolphin" memory, as they are displayed on offer. These were recognized by the system immediately, correctly configured and operational by now properly.

The reaction of Diewald Memory was quick and friendly. The error analysis was a bit bumpy (z. B. the knee-jerk statement that there would be some subtypes of the model Studio 1535, which could not handle 4GB of RAM, or rather amateurish exchange one of the two CSX modules against a non-type the same), but ultimately effective. The seller was always cooperative and made no difficulties concerning testing and conversion.
