ASUS A88X-PRO Motherboard

Memory Support

AMD 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 FM2 processors supports DDR3 memories up to 1,866 MHz. FM2+ CPUs memory specifications are not informed by AMD to date. According to ASUS, the A88X-PRO supports memories up to DDR3-2400.

The ASUS A88X-PRO has four memory sockets. According to the manufacturer, it supports up to 64 GiB if four 16 GiB memory modules are used.

In order to enable the dual-channel mode, you must install four or two identical memory modules. If you are using two modules, you must install them in sockets of the same color if you want the best possible performance.
