For the strips to the laptop, nothing more to say it's perfect. By cons I have a problem with 2 lots of 1GB modules (whereas I had encountered any during my previous order (modules installed and tested, perfectly ok!). This time, after installing the first game, on an HP Compaq, no problems. For against another identical micro HP compaq, I set the second set, the bars are recognized, but after passing through setup to validate the change, most display at all, even after waiting several minutes. I then tested the second set on the first microphone that worked (the first set), same problem (barrettes recognized in the setup, but no display, no beep, nothing). So I removed the second game and puts in place the first game (the one that worked fine) and there, same problem. I lost my Latin. I then removed the bars ordered and delivered 2 original strips (512 Mb each). And my microphone works, but with 1GB of origin. What should I do?
