Introduction to dual-channel memory technology

The dual-channel memory technology is actually a kind of memory control and management technology. It depends on the memory controller of the chipset. Theoretically, it can double the bandwidth provided by the two memory of the same specification. It has long been used in servers and workstation systems, but it has come to the technical front-end to solve the increasingly embarrassing Bandwidth bottleneck of desktops. Dual-channel memory installation has a lot of attention. For boards using i865 and i875 chipset, most of these types of boards currently have four dimm slots, each of which represents a memory channel, only when both groups of channels have the same memory installed can the memory work in dual-channel mode. At the same time, the installed memory must be symmetric (Channel A has 1st slots and channel B has 1st slots, or channel A has 2nd slots and channel B has 2nd slots ). For ease of installation, some manufacturers currently have their own motherboard marked the symmetric memory slots with different colors. You only need to install the memory on the dimm slots with the same color. After the installation is successful, the system will display that the memory is working in dual-channel mode during self-check. For the nforce2 motherboard, although there are two separate data lines for the DDR memory dual-channel mode, when the user inserts a single DDR memory, the motherboard is automatically locked in single-channel mode. Therefore, if you want to effectively use the dual-channel DDR memory of the nforce2 motherboard, you must use an even number of memory entries, and it is best to install the same manufacturer and the same specification according to the correct method. During installation, the memory must be correctly installed according to the color icon on the dimm slot of the motherboard, so that the two memory controllers can work at the same time to implement the dual-channel DDR function.
