ok i will surely order the ram that @Joe C found as both are exacty identical and i think the problem will probably solved after that but i would like to know why the ram i bought didn't work when it has basically the same specs and the same speed than the original one. if somone could answer about this mystery, that would be nice.
Looks to be a legitimate store but it does not look like that memory has the right label Is there an item number different from my link than the memory item number that you purchased? (I can't read french)
i don't know what you're talking abou, i already psted all the needed details about the ram andi dont think it matters to know which item number it is. btw i tested the new ram with memtest to see if it is working well and noticed that few minutes later while the test it is still running, the pc crashes so logically that would mean that the ram does not work properly.
