What does dual channel mean, is it good?

Dual-channel is good and fast.

Let's take an analogy, between A and B, there are more vehicles passing through one 4-lane road and two 4-lane roads per unit of time.

Dual-channel memory means that more data is transferred to the CPU per unit of time than a single channel.

Dual-channel, in fact, is two memory controllers. What does memory control mean? If the CPU is like a factory, and the memory is like a warehouse, then the memory control is the warehouse manager.

A single channel means that there is only one door from the factory to the warehouse, and one administrator can only pick up one batch of goods at a time. The double channel is to build another warehouse, and one more administrator, and at the same time provide raw materials to the factory, and the raw materials provided each time are doubled...

We increase the memory is equivalent to increase the warehouse, the warehouse is large, the stock is sufficient, the factory does not have to go out to buy things, the production speed is naturally fast. There is one more warehouse manager, and there is one more outlet to supply raw materials to the factory, and the speed at which the warehouse supplies raw materials to the factory is accelerated, and the factory is naturally happy. That's probably the truth.

As for what supports dual channels. This is to be said separately.

1. For all Intel CPUs, and AMD K7 products with SOKET462 architecture, whether they support dual channels mainly depends on whether the motherboard has two memory controllers and whether there are two warehouse administrators, because the memory control of the above system is done in the northbridge chip of the motherboard, that is, the organizational relationship of the warehouse administrator belongs to the motherboard, so whether it supports dual channels has nothing to do with the CPU.

2, all the K8 of AMD, and now the new 754 architecture of Sempron, their system memory controller is in the CPU, that is to say, the organizational relationship of the warehouse administrator belongs to the CPU, so, this system, whether it supports dual channels, the CPU has the final say, and the relationship with the motherboard is beautiful. For example, all 754-pin CPUs can only support single channels, not dual channels. All 939-pin CPUs support dual channels.

As for what motherboards support dual-channel? Our common Intel chipset, above 848,865PE (no E, no good), will support dual channels. For other VIA and SIS chipset motherboards, you should check whether it is dual-channel in its product information.

If it's the second case above, you just have to think about whether to buy AMD for 939 or AMD for 754.

When inserting dual-channel memory, you also need to look at **, if it is two, then say that it should be in orOtherwise, it will not play the role of double pass.

**The processor is faster, more responsive, and more efficient.

Dual-channel means that the processor is fast, for example, with two 512 memory, wow, the speed is great.

Okay! That's a great way to increase memory bandwidth!!
