The product can be installed on a motherboard that has only one memory channel. These channels are connecting circuits between the CPU and memory modules, and end in slots where RAM modules (commonly referred to as RAM sticks) can be installed. When the CPU is active, it sends instructions to the Front Side Bus of the chipset of the motherboard. The latter, in turn, sends those instructions through the memory controller to the memory channel. The memory modules connected to the channel then act as a buffer, holding the data while it is being processed by the CPU. The chipset being described supports a single memory channel, which means it can transfer data to at most two memory modules. The modules may be single data-read type (SDRAM), or double data rate - read type (DDR).
