What is the difference between single sided and double sided computer memory, single bank and double

The double-sided compatibility is better, the particles are more, and there is not much difference in use.

Single-sided memory refers to memory particles that are integrated on one side of the memory module, and double-sided memory refers to memory particles distributed on both sides of the memory module. Single-sided and double-sided memory is not good or bad in itself, and the difference is very small, which is described as follows:

1. There is no difference between single-sided memory and double-sided memory in terms of electrical performance, single and double refers to whether there are particles on one side or both sides on the PCB board of the memory, if a single particle is 64MB, single-sided is 64*8=512MB, and double-sided is 1024MB, so double-sided memory is relatively easy to increase capacity.

2. From the perspective of production process, the production of single-sided memory is also simpler than double-sided memory, so the memory seen on the market is mainly single-sided products. With the same capacity of memory, the integration degree of single-sided memory is higher than that of double-sided, and the production date is lower, so it is more stable to work.

3. For the same capacity of memory, it is recommended to buy single-sided memory, because the level of single-sided production is relatively high, and single-sided memory only occupies one bank, some motherboards can only support 4 banks, and 4 slots are full if 2 double-sided memory are used, and the other two slots may not be used.

This is the in-memory computing elimination method, provided that it is based on the relationship of the CPU.

1. The bit width of the CPU data bus is generally 64 bits, and this bit width is called the physical bank

2, then memory 1rx4 represents one 64-bit, and x4 represents the number of bits of memory per memory particle. From here, we can easily know that the number of memory particles is: 64 4=16.

If it is 2rx8, the memory particles are: 64*2 8=16 chips. 2rx4 is 64*2 4=8 pieces.

3, so whether it is 1rx4, 2rx4 or 1rx8, 2rx8, the meaning of the representation can be understood as the number of memory particles of memory. Instead of single-sided or double-sided memory.

Extended Material: Back to Bridge

A memory module is a computer component that the CPU can address through the bus and perform read and write operations.

Memory modules used to be an extension of the main memory in the history of personal computers. With the continuous update of computer software and hardware technology, memory modules have become the whole of read and write memory. When we talk about the size of a computer's memory (RAM), we refer to the total capacity of the memory module.

Memory modules are an essential part of a computer, and the CPU can address the memory through the data bus.

Historically, computer motherboards had main memory, and memory modules were extensions of the main memory. Later computers will not have main memory on the motherboard, and the CPU will rely entirely on memory modules. All content on external memory must pass through memory in order to function.

1. Difference in particle combination mode. For an 8 GB memory, a single-sided memory module has a single-grain capacity of 2 GB x 4, and a double-sided memory module has a single-grain capacity of 1 GB x 8. Single-sided memory modules of the same capacity are only distributed on one side of the memory module, while double-sided memory modules are distributed on both sides. Single-sided memory modules of the same capacity have a larger single-grain capacity.

2. Differences in production processes. Single-sided memory modules of the same capacity have a higher degree of integration than double-sided memory modules, and the technology is more advanced. In fact, it is not difficult to see from the memory module, whether it is a single-sided memory module or a double-sided memory module, its specifications and sizes are the same, and the single-sided memory module needs to collect more particles and lines on the same PCB version, which is more difficult.

In general, we do not recommend using single-sided memory and double-sided memory at the same time, as compatibility issues often occur.

In fact, there is no good or bad difference between single-sided and double-sided memory, and the difference is very small, but from a technical point of view, for memory of the same capacity, single-sided memory is more integrated than double-sided memory. Its electrical performance is better, the anti-interference ability is stronger, and the stability is higher. Existing big brand memory manufacturers (such as Kingston and Kingtiger) are vigorously promoting this single-sided design of memory modules.

Because the electromagnetic shielding, anti-interference, and purity of the pulse signal of the single-sided noodle are better than the double-sided structure, the compatibility and stability problems encountered by the single-sided memory are fewer, and the performance is better, and the probability of damage to a single memory particle is also reduced.

Therefore, it is recommended that when multiple memories are used at the same time, it is better to use a single memory.

The reason is that yours is an old motherboard....There are motherboards that are double-sided, and the next time you buy a motherboard, you have to ask clearly

There is little difference between single-sided and double-sided memory modules in terms of quality, but they are divided into single-sided and double-sided because of the different designs of PCB boards and the different types of chips used. The main differences between them are as follows:

1) The integration degree of memory IC is different. For example, the 168-line 128MB single-sided memory uses a 128Mbit-sized 16M 8-bit IC, while the double-sided IC uses a 64Mbit-sized 8Mbit.

2) The production cost is different, and the memory cost of double-sided is lower.

3) Compatibility is different, for some chipsets, the memory strip on one side is better than the compatibility on both sides.

The capacity of memory is the sum of the capacity of all granules.

Double-sided means that there are particles on both sides, and single-sided means that only one side has them.

For example, if a memory manufacturer buys a batch of memory chips with a size of 64MB to make 1GB of memory, a total of 16 memory chips are pasted on both sides.

It's still this batch of particles to make a 512MB memory, and 8 pieces need to be pasted, so it's okay to stick it on only one side, so there is a single-sided memory.

A memory module with particles on both sides is called a double-sided memory module, and a memory module with particles on only one side is called a single-sided memory module. Some motherboards do not support single-sided or double-sided memory modules well, resulting in failure to recognize the correct capacity or failure to boot.

There are two types of memory: single-sided and double-sided, usually single-sided memory has one set of banks per line, while double-sided memory provides two sets of banks per line.

Single-sided and double-sided memory have their own advantages: single-sided stability and good double-sided compatibility.

1. The memory is divided into single-sided and double-sided. Double-sided memory is an older technology, while single-sided memory is a new technology. The biggest advantage of the old technology is that it is compatible.

2. Double-sided memory is because the capacity of a single particle is low, in order to accommodate a larger capacity, a lot of particles must be used, and it must be used on both sides.

3. Double-sided memory, because the circuit is complex and there are many particles, so there is more probability of failure. Single-sided memory, on the other hand, has a simple circuit, a small chance of error, and a high stability rate.

Single-sided: Higher integration helps with heat dissipation.

The existence of single-sided and double-sided memory is due to the use of two different manufacturing processes to manufacture. Memory made with a single particle is single-sided, and memory made with a double-particle is double-sided.

There is no good or bad between single-sided and double-sided memory, the difference is very small, the same capacity of memory, single-sided is more integrated than double-sided, and the production date is lower, so it is more stable to work.

What users should pay attention to in use is:

1. There will be incompatibility between the same surface memory, and the probability of incompatibility will be higher if the single and double-sided memory are mixed, so try not to mix them.

2. Some old motherboards support memory in addition to capacity, there are certain restrictions on the memory surface, although there are free slots on the motherboard, which exceeds its support range, it is not supported, so you need to use single-sided.
