RAM 256, virtual memory 2G, is it reasonable? 20

Doesn't work properly. Virtual memory is on the hard disk, and the read access speed of the hard disk is far less than the physical memory, virtual memory is just a place where the system stores the data that is used less frequently, and when the physical memory cannot meet the storage of most commonly used data, there will be problems. Therefore, the physical memory is small, and the virtual memory is useless no matter how large it is.

The 256MB memory should be set between 768-1536, if it is too large, your C drive space will be larger. This file is set to the larger the virtual memory, the larger the file will be, but it is usually set this way. If it's too small, you won't have enough memory.

Generally I set it to a C disc 768-1536This is just my personal opinion.

Unreasonable: It is enough to set the virtual memory to 500-1000.

The virtual memory can be changed by itself.

It's useless to be so big.,It's appropriate.,Is your computer a video memory shared memory?,If you can adjust it in the BIOS.,Make the memory a little bit.,That program should be able to run but it's very slow!

1 is the case of virtual memory, which is allocated by the system itself, and if you want to set it properly, 1 is usually set to twice the size of the memory module.

The phone memory of 256g is better.

The main difference between 128G and 256G memory is that the storage space is not the same, and the read and write speed is different. First of all, the storage space of 256g is twice as much as that of 128g, and it can store more**, **, **, etc., so you don't have to worry about running out of space when you use it.

Secondly, they will have some gaps in the speed of data reading and writing, usually 256G is faster. The choice of Qingzaoqi 128g or 256g depends on the individual's dosage needs, because everyone has different storage space requirements for mobile phones.

The difference between 128G and 256G of mobile phone memory:

1. The main difference is the size of the space. Since the storage space of 256G is twice that of 128G, it can store more things, and the mobile phone will be available for a longer time, so you don't have to clean up the space often, and naturally you don't have to replace the large-capacity mobile phone every once in a while.

2. Secondly, they have some not very obvious differences, such as the speed of the two in the reading and writing of data is not the same, generally 256G memory is faster than 128G, when installing APP, depositing or reading data, it takes less time, but because these operations are not commonly used, the difference between the use of speed is not obvious.

It is still necessary to set the memory 32g.

Virtual Memory Setup Tutorial:

1. Click the "Start" menu on your computer (or press the Windows key on your keyboard), right-click "Computer", and select "Properties".

<>3. Select "Advanced" in the "System Properties" dialog box, and then click "Settings" under "Air Bridge Positive Performance Regret".

4. In the Performance Options dialog box, click Advanced and Change.

5. In the "Virtual Memory" dialog box, check "Automatically manage paging file size for all drives", and its virtual memory will be automatically allocated.

6. If you don't need to set the virtual memory automatically, you can set the virtual memory manually. Remove the paging file size for all drives in front of Auto Management, then select Custom Size, and enter the initial size and maximum value you want to set.

For example, the initial size is 2000 and the maximum value is 8000. After entering the values, click "Settings" and "OK" to restart the computer.

7. If only one hard disk is installed on the computer, then the virtual memory settings are valid in almost any partition.

If you have multiple hard disks installed on it, choose other hard disk partitions as virtual memory, which can improve the efficiency of the operation (i.e., one hard disk has no data storage and virtual memory usage at the same time).

512M memory and 256M memory can be mixed together, where the memory capacity is 768M, this result is not 2 n can be represented, but practice has proved that this capacity is available, even if a 1025M memory is made, it can still be used, no problem, it is not convincing to say that this is the power of 2 n. It is believed that this has something to do with the internal structure of the memory module.

The following is a personal opinion, the master Mo spray:

1.The memory unit is in the form of a matrix (called a bank), which can be thought of as a rectangle. If you want to determine the location of a storage unit, you need to determine the addresses of its rows and columns (the coordinates of the x,y direction in the rectangle), and if the address decoder in the American direction in memory has n bits, then the maximum number of addresses that can be found is 2 n (x,y in the rectangle can represent the maximum value of the direction).

Notice the "maximum" I mentioned, i.e. less than this value. (Suppose the x direction can represent the maximum value of 2 n, and the y direction can represent the maximum value of 2 m, then this rectangle can represent 2 (m+n) storage units) If you don't want to be a multiple of 2 now, you just like singular numbers, such as 2 (m+n)-3, what does this mean? This means that it is of course a silly thing to have 3 cells empty on the rectangle without making storage cells without changing other circuits.

Therefore, at the level of bank, it is determined that it is a multiple of 2.

2.There are also multiple banks on a memory chip, and the general situation is also a power of 2, so I can't explain this from the circuit level.

3.The bit width of the chip on a chip is 8 bits, according to the formula:

Particle density = data depth chip bit width l-bank number, where "data width" = "storage unit in one matrix", "particle density" = "total data size on a memory chip".

4.If you look closely, the number of memory particles on the memory module is also a full power of 2, and the memory module in the figure below has 8 memory particles on one side, and if there are also on the other side, it is 16, or 2 n can be represented.

In this way, why it is a multiple of 2 can be explained. The last equation:

Total capacity of memory modules = particle density Number of particles (chips).

The primary square of 2 is 2---2x1

The quadratic is 4---2x2

The cubic is 8---2x2x2

To the fourth power is 16---2x2x2x2

Got it, multiply by 2 on the previous base each time

If the logo is not uniform, there will be a short catty and less two.

Multiply it by 2 on the original basis.
