    I bought a used macbook pro 15 mid 2012 and the previous owner upgraded the memory to 16 gb with 2x8gb 1333mhz ram,Is there any problem with the speed of the ram because this model's normal ram speed is 1600mhz? This model has an onboard Intel Hd 4000 graphics card that shares memory with system and a second NVidia 512mb,that's why I'm asking, because of the onboard Intel Hd 4000.

    shouldn't be any problem, will just run slightly slower.

    How does it WORK?
    Does it run smoothly as it is now?
    No crashes?

    If yes, my suggestion is... leave the RAM alone.
    Use it and be happy.

    Hmmm... does it still have a platter-based hard drive inside?
    Replacing that with an SSD is cheap and EASY to do.
    A 15-minute job -- anyone can do it.
    That will make it feel like a new Mac !

    It runs very nice and very very fast and I have an ssd inside,I was afraid of the onboard graphics card which shares memory with the system

    RAM speed is trivial and does not give a significant performance benefit. The problem is that the faster the RAM, the higher the latency is.

    I bought a used MBP 2012 15" and I upgraded the 4GB to 2x 8GB 1333 I had from an old iMac 2011. Works fine. I don't think 1666 is significant difference.
