The only difference between four memory lines and two memory lines is the number of memory slots, and there is no difference in the use of computers. Four internal memory and dual internal memory are used by most computers, and the speed is not much different.The improvement of four channels to two channels is only a theoretical improvement. In practical applications, ordinary daily applications are basically the same. Only 3D games and professional software with large loads can be actually improved, but the effect is not very obvious. The number of memory sockets on the motherboard corresponds to the maximum number of memory channels supported on the motherboard.For example, two memory sockets mean that the motherboard supports up to two memory operation channels.It can be understood that the motherboard can read and write memory from two channels at the same time.The power consumption of four memories is slightly higher than that of two memories.If the total capacity is the same, two memories are more stable than four memories, and the failure rate of installing two memories is less. There are limited memory slots on the PC motherboard.Desktop computers generally have four slots or two slots, but laptops can have up to two slots.If there is a great demand for computer memory, you can insert two 8g memory sockets to fill all memory sockets.However, if only one 16g memory socket is inserted, the remaining memory sockets can be retained, which is equivalent to saving the cost of future upgrades.
Extended information: Four memory and dual memory are called memory multi-channel, and memory multi-channel refers to the design of multiple memory controllers at the North Bridge chip level (also called MCH).These multiple memory controllers can work independently of each other, and each controller controls a memory channel. Disadvantages of memory multi-channel: 1. Memory of different brands may have compatibility problems. 2. If you use the new large capacity memory on the old motherboard, it may exceed the memory capacity limit of the old motherboard.It is mainly manifested as BIOS identification error, or memory overflow and other problems. 3. Heat dissipation and ash deposition.The use of four memory may affect the cooling capacity to some extent;If two memories are used, the idle memory socket is prone to dust accumulation for a long time, and poor contact may occur when necessary.
