Hello,
the compatible RAM for my PC is "DDR3 12800U", and I've been told that "Unbuffered" is the same as the little "U". Is that true? :)

Best regards, Mathéo.

    Hi,

    The "U" DIMMs are indeed "Unbuffered" memories, yes.

    Some motherboards only accept "UDIMMs," while others only accept RDIMMs, and finally, some accept both but are unable to have both types coexist at the same time.

    In other words, if you already have "Unbuffered" modules (which is the majority of cases), you will need to acquire identical models. :-)

      My original RAM is a "12800U", so yes, I need to take Unbuffered.
      Just one last question, is this RAM: https://www.crucial.fr/, compatible with my PC, as I don't see what "NON ECC" refers to?

      And I normally have 4GB of RAM but on "Can you run it," apparently I have 3 ?? O.o

      Sorry for all these questions ^^

      ECC memory is error-correcting memory, not useful in your case, since it is generally intended for servers and workstations, as it requires a compatible motherboard and processor.

      To check the amount of memory, simply right-click on the bottom left corner of your screen (where the Windows icon is) and open the "Task Manager" to see the total amount of memory present in the machine via the "Performance" tab.

      Finally, be careful about the format if you have a laptop; a different memory module format will be required, which you did not specify, so it is impossible to confirm whether the format is suitable for your machine.
