depends on what kind of ram it is. they have Ripjaws V series ram for both DDR3 and DDR4 types of ram and the z270 boards only support DDR4
So then yeah it should support it? Its DDR4 so
it should work, but to be safe make sure its a speed you motherboard supports although if the ram is rated faster then your motherboard supports it will just downclock it. for example, if your motherboard has a H170 chipset then it with only support DDR4 ram at a speed of 2133mhz.
