Advantages and disadvantages of asymmetric dual channel and symmetrical dual channel

Psychological effect, you don't feel it at all when you use it, I use a 2g

One 1g for two Kingston 1g

The memory module is composed of symmetrical dual channels, which is not much different from the dual channels composed of 2 different brands. There's no need to dwell on that!

The differences between dual-channel and asymmetric dual-channel are: different limits, different total memory, and different operations.

1. The restrictions are different.

1. Dual-channel: Dual-channel must be of the same size, the same particle, and the same batch of memory can be composed.

2. Asymmetric dual channel: Asymmetric dual channel has no strict restrictions on the particles, batches and even size of the memory.

Second, the total amount of memory is different.

1. Dual-channel: The total amount of the two sets of memory as dual-channel on the motherboard socket is equal.

2. Asymmetric dual-channel: The total amount of the two sets of memory on the motherboard socket does not have to be equal.

Third, the operation is different.

1. Dual-channel: Dual-channel can operate at the same time with zero waiting time between each other.

2. Asymmetric dual channels: Asymmetric dual channels cannot operate at the same time with zero waiting time between each other, and need to operate in sequence.

The difference between single and dual channels is in requirements, capacity, rate, etc.

1. The requirements are different, memory modules.

A single channel requires one memory module, and a dual channel requires at least two memory modules.

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 read and write of memory use different channels, which can be read and written at the same time, and the memory bandwidth.

Double. 4. The processing capacity is different. Dual-channel has an advantage over single-channel in terms of reading and writing, and it is certainly faster than single-channel to open software or documents on a daily basis. For example, it used to run some large games.

, due to the memory bandwidth issue, the performance improvement brought by dual channels can be clearly felt.

Dual-channel memoryNotes:

On the current mainstream chipset.

Dual-channel technology is almost perfectly supported, and is divided into two sets of designs, with the same color. Generally speaking, users can achieve dual channels by inserting two memory slots of the same color into two memory slots.

But there are always exceptions, for example, some motherboard manufacturers are used to using one color of the socket to represent channel A and channel B to use another color, at this time you need to open the manual to confirm, but the general principle is the method of "interlaced insertion".

The difference between dual channel and single channel is the difference in transmission speed.

Dual-channel memory is more efficient for data transfer than single-channel, especially for computers that don't have a discrete graphics card and use a core graphics card, which supports better graphics performance when using dual-channel. A single channel requires only one memory module, while a dual channel requires two RAM and two motherboard memory slots. For the same amount of memory, two strips will be more expensive than a single strip.

Memory dual-channel is to design two memory controllers at the Northbridge (also known as MCH) chip level, and the two memory controllers can work independently of each other, and each controller controls a memory channel. In these two memory, the CPU can address and read data separately, doubling the bandwidth of the memory and doubling the speed of data access (theoretically).

Dual-channel feature

The popular dual-channel memory architecture is built with two 64-bit DDR memory controllers with a bandwidth of up to 128 bits. Because the two memory controllers in the dual-channel system are independent and complementary intelligent memory controllers, they can operate simultaneously with zero waiting time between them.

This complementary "nature" of the two memory controllers allows for a 50% reduction in effective wait time, doubling the bandwidth of memory.

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.
