ASRock Z87 Extreme4 Motherboard

Memory Support

Intel socket LGA1150 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.

The integrated memory controller from socket LGA1150 processors supports DDR3 memories up to 1,600 MHz. According to ASRock, the Z87 Extreme4 supports memories up to 2,933 MHz.

The ASRock Z87 Extreme4 has four memory sockets. Since DDR3 memory modules can be found in capacities up to 8 GiB, you can have up to 32 GiB with this motherboard if you use four 8 GiB modules.

In order to enable the dual-channel mode, you must install two or four memory modules. Unfortunately, on the ASRock Z87 Extreme4 all memory sockets are black. In order to enable dual-channel mode and achieve the highest performance possible when installing two memory modules, you must install the first module in the first socket and the second module in the third socket (i.e., you must skip one socket).
