Simple two channel question this 20 points are easy to get .

The symmetrical dual-channel working mode requires the memory capacity of the two channels to be equal, but there is no strict requirement for the absolute symmetry of the memory capacity, which can be 512MB +512MB for channel A and 1GB for channel B, as long as the total capacity of channel A and channel B is equal. Dual-channel mode is available with 2, 3, or 4 memory modules, depending on the speed of the memory module installed in the system, if the speed of the memory module is different. The details are as follows:

1) Absolute symmetry of memory modules. This is the most ideal symmetrical dual-channel, that is, insert the same capacity of memory sticks in the same color slots, the number of memory modules is 2 or 4, and all the memory in this mode works in dual-channel mode, which has the strongest performance.

2) Symmetry of memory capacity. This mode does not require the same number of memory modules in the two channels, and can be composed of 3 memory channels to form a dual channel, and the total memory capacity of the two channels is equal, and all the memory also works in dual channel mode) The performance is slightly inferior to mode (1). The motherboard chipset will automatically detect the memory module and will automatically work in single-channel mode if it finds two separate slots of the same capacity installed in different slots.

Therefore, it is advisable to insert the same capacity of memory modules in the same color slot for relatively better performance.

This question is scored by the platform.

At present, the mainstream configuration, AMD has strict requirements for dual channels, which must be of the same capacity and specifications, and two or four memories can be composed, otherwise it will not work, it is only a single channel. AMD's dual-channel has little impact on performance.

The IN platform is more dependent on dual channels, and the CPU of the i7 is not included in it, because IN does not integrate a memory controller into AMD's processor, and it needs to go through the motherboard to obtain data, so I won't go into details. However, its requirements for dual channels are relaxed, which can be composed of different capacities, different frequencies, and even three memory, and such channels are called elastic dual channels. Dual-channel IN platform performance can be improved by more than 15%, compared to AMD's 5%, or even less.

Dual-channel must be plugged into the same color slot, and most motherboards support dual-channel. Plug it in and it will automatically turn on.

As long as the motherboard supports plugging in, it will be turned on by default...

In the early days, the motherboard dual-channel had to have the same specifications, but now in the era of mixed plugging,,, two or three can be plugged in and turned on by default.

With the same capacity and frequency, dual channels are faster than single channels...

The size of the memory is more important than the dual-channel and frequency.

If it is not a memory module of the same frequency and capacity, it cannot be combined with a dual-channel, three-channel, or four-channel. If you don't use that, don't talk about symmetry and asymmetry.

Aging causes! And the memory is too cluttered.

I think you should ask him what kind of graphics card he is.

1. The requirements are different, a single channel of memory modules means that one memory module is required, and a minimum of 2 memory modules are required for dual channels.

2. The memory capacity is different, in the case of a single 2G, a dual-channel is 2 memory sticks, and a single channel is 1 memory module.

3. The read speed is different, and the single-channel memory can only read or write at the same time; Dual-channel means that the memory can be read and written in different channels, and the memory bandwidth can be doubled at the same time.

4. The processing power is different: dual-channel has an advantage over single-channel in reading and writing, and it is definitely faster than single-channel to open software or documents in daily life. For example, when running some large games, it was a bit difficult due to memory bandwidth problems, but the performance improvement brought by dual channels can be clearly felt.

5. Difference in installation cost: for the same capacity of memory, two will be more expensive than a single memory, so you can also consider the actual configuration of your own computer when you group dual channels (generally it is recommended to use dual channels for computers that use core graphics).

The above content refers to Encyclopedia - Dual Channel.

The difference between dual-channel and single-channel is that the main body is different, the memory capacity is different, the read speed is different, the processing capacity is different, and the installed cost is different.

1. The main body is different.

Single-channel computer memory has only one channel. Dual-channel is a memory control and management technology that relies on the chipset's memory controller to work to theoretically double the bandwidth provided by two identically sized memories.

2. The memory capacity is different.

Dual-channel is 2 memory modules, and single-channel is 1 memory module.

3. The reading speed is not the same.

Single-channel memory can only read at a time, or can only write; Dual-channel means that the memory can be read and written in different channels, and the memory bandwidth can be doubled at the same time.

4. The processing capacity is different.

Dual-channel has an advantage over single-channel in terms of reading and writing, and it is definitely faster than single-channel to open software or documents on a daily basis. For example, when running some large games, it was a bit difficult to run some large games, but the performance improvement brought by dual channels can be clearly felt.

5. The installed cost is not the same.

With the same capacity of memory, two bars will be more expensive than a single bar, so you can also consider the actual configuration of your own computer when you group dual channels.
