    Is this configuration possible if you buy the base nmp with three 4 gb sticks and get the 1 x 16 gb stick from outside?

    no the 16gb ram is not compatible with the rest of the ram.

    cause 4 & 8gb are Unbuffered (UDIMM)

    while 16 is Registered (RDIMM)

    so you can mix 4 & 8gb but just not 16gb

    Incorrect, the 16GB sticks are not compatible with the 4GB and 8GB memory modules. The 4GB and 8GB memory modules can be mixed.
