Re: 2x16GB + 2x32GB RAM (P72 / P52)

Both P52 and P72 machines are currently being sold on the sales site with 4X32GB so it is possible.  I have seen reports of people having problems adding DIMMs that were not Lenovo-brended.  The first startup after adding or changing memory can take a long time while the machine updates the configuration.  People give up and turn it off when there is no problem. When I upgraded my P70 from 2X16 to 4X16, it took just over 2 minutes for the first boot.  After that, it was quick, like normal.  Turn it on and go get a cup of coffee.  If you buy non-Lenovo RAM, always check the seller's return policy.  32GB DIMMs are expensive.
