Does memory dual channel make a big sense? 10

DDR itself is dual-channel memory.

At present, the computer is equipped with DDR, even if you want to install a single-channel, it is no longer compatible, and for the earlier motherboards, you can only install single-channel memory, which is not compatible with dual-channel memory. Therefore, this issue is only a historical concept, and there is no point in talking about it now. Since you're interested, you might as well show off.

In the Ben-San and earlier periods, the memory used was single-channel, and the amplitude of the current fluctuation had two directions, positive and negative, and the single-channel memory could only read data in the positive or negative direction, that is, the data could only be read once per current fluctuation. With dual-channel memory, data can be read in both positive and negative directions, so the reading speed is twice as fast.

For motherboards of the past, installing two single-channel memory of the same model (note that it is the same model) can achieve dual-channel reading effect on motherboards that support single-channel, so the performance is greatly improved, but now that dual-channel memory dominates the world, this is really too meaningful.

I've had this question before.

Dual-channel is actually not much different for our average users, and the general use will not feel the performance improvement! For economic reasons, it is better to pay for the bill.

It mainly depends on what your CPU chooses, the same upstairs view.

If you want to say that single bar is compared to dual pass, it must be that single bar has an advantage, and remember that the less stuff on the motherboard, the better it is for the motherboard.

What are you scribbling, the overall performance of dual-plus 1G is 5-10% higher than that of single-and-2G memory, and it doesn't make much sense?

There are many reviews on the Internet, you can take a look, and the current conclusion is basically that the efficiency is doubled.

It is not big, and I don't feel it in ordinary use basically.

When it comes to dual-channel memory systems, we are most concerned about the increase in memory bandwidth it brings. In order to solve the memory performance bottleneck problem in the current system, memory manufacturers simply increase the operating frequency of memory, which is much easier than developing new types of memory, and of course the cost is correspondingly much lower. However, due to the characteristics of the transistor itself and the constraints of manufacturing technology, the speed of memory particles cannot be increased indefinitely, so before the development of new memory, dual-channel memory technology has become a technology that can effectively increase memory bandwidth.

Its biggest advantage is that by changing the way the memory is controlled, the memory bandwidth can be increased on top of the existing memory.

From the theoretical point of view, dual-channel memory technology has considerable advantages. The theoretical bandwidth of the dual-channel DDR400 is exactly matched with Intel's 800MHz P4 processor and i865 and i875 chipsets on the front-side bus, which is why Intel switched to support DDR400. The dual-channel DDR400 is selected for the P4 platform with a front-side bus of 800MHz, which has a lot to do with the dual-channel memory control and management mechanism and high bandwidth.

Built a dual channel and it doesn't feel great.

Not too. Up to 10% up to the maximum.
