I have 16gb 1866mhz of ram in mine witch runs at its fullest 933. if you want to put 32gb you can only put 1600mhz it will not support 32gb of 1866mhz I thin kit has something to do with the MHz for each slot it can handle or something like that but any way my ram is great never had any problems and it works great
