This article mainly introduces what memory technology allows simultaneous access to two memory modules, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

Dual-channel memory technology allows simultaneous access to two memory modules. Dual-channel memory technology is actually a memory control and management technology, which depends on the memory controller to function, which can theoretically double the bandwidth provided by two memory of the same size.

Dual-channel memory technology allows simultaneous access to two memory modules.

Dual channel, that is, two memory controllers are designed in the chip level of Beiqiao (also known as MCH). The two memory controllers can work independently of each other, and each controller controls a memory channel. In these two memory pass CPU, the data can be addressed and read respectively, so that the bandwidth of the memory is doubled and the data access speed is doubled accordingly (in theory).

The popular dual-channel memory architecture is constructed by two 64bit DDR memory controllers with bandwidth up to 128bit. Because the two memory controllers in the dual-channel system are independent and complementary intelligent memory controllers, they can achieve zero waiting time between each other and operate at the same time.

This complementary "nature" of the two memory controllers can reduce the effective wait time by 50%, thus doubling the bandwidth of memory. Although this new specification is mainly the change between the chipset and the host board, the purpose of dual channels is to solve the problem of memory bandwidth, so that the motherboard can achieve 6.4GB/s even if only DDR400 memory is used.

Dual-channel is a new technology adopted by the motherboard chipset (Athlon 64 is integrated into CPU). It has nothing to do with memory itself. Any DDR memory can work on the motherboard that supports dual-channel technology.

Dual-channel memory technology is actually a memory control and management technology, which depends on the memory controller of the chipset, which can theoretically double the bandwidth provided by two memory of the same size.

It is not a new technology and has long been used in servers and workstation systems. it is only in order to solve the increasingly embarrassing memory bandwidth bottleneck of desktops that it has come to the foreground of desktop motherboard technology.

A few years ago, Intel launched the i820 chipset that supports dual-channel memory transmission technology, which formed a golden pair with RDRAM memory, and its outstanding performance made it the biggest bright spot in the market for a while, but the defect of high production cost caused the situation that it was not popular, and was finally eliminated by the market.

Since Intel has abandoned its support for RDRAM, the dual-channel memory technology of mainstream chipsets refers to dual-channel DDR memory technology.

Thank you for reading this article carefully. I hope the article "what memory technology allows you to access two memory modules at the same time" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
