ASUS Z87-A 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 ASUS, the Z87-A supports memories up to 2,800 MHz.

The ASUS Z87-A 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. On the ASUS Z87-A, the first and third memory sockets are yellow, while the second and fourth are black. When installing two memory modules, use the yellow sockets.
