Memory Support

Intel socket LGA1151 CPUs have an embedded memory controller, meaning that it is the processor, not the chipset, that defines what memory technologies you can have and the maximum amount of memory that is possible. The motherboard, however, may have a limitation as to how much memory can be installed.

These CPUs are compatible with both DDR3L (up to 1,600 MHz) and DDR4 (up to 2,133 MHz) memory. So, it is the motherboard that defines which memory type (DDR3 or DDR4) can be installed, since DDR4 slots are physically different from the DDR3 slots. According to ASRock, the Fatal1ty Z170 Gaming K6+ supports DDR4 memories up to 3,866 MHz.

The ASRock Fatal1ty Z170 Gaming K6+ has four memory sockets. You can install up to 64 GiB with this motherboard if you use four 16 GiB modules.

In order to enable the dual-channel mode, you must install two or four memory modules. On the ASRock Fatal1ty Z170 Gaming K6+, the first and third memory sockets are red, while the second and fourth are black. When installing two memory modules, use two sockets with the same color.
