About desktop memory modules, how to choose memory modules for desktops

I recommend you ADATA!! As we all know, Kingston and Hyundai used to be the best memory sticks, as the saying goes, there are too many fake Kingston and Hyundai, so to speak, and the Kingston and Hyundai that you see now in Technopolis are fake!! Although the fake one can be used, it is very likely to be unstable when dealing with memory-consuming programs.

Although ADATA is a domestic brand, due to the lack of fake ADATA in the market, and ADATA's memory modules have been doing very well in recent years, and they are not worse than those big brands, so I recommend ADATA.

When the landlord wants DDR400 it! If it's DDR400, you can find some Kingston and modern genuine products in the second-hand market, good luck!!

Kingston is the most compatible, and the speed of the Aegon is hard enough, and I know it; I have used it in modern times, and I advise you not to (pick the board to scare you).

Buy 1g Kingston quality is very good, but ** very high, generally about four hundred, it is recommended to buy Weigang,** is quite reasonable, about two hundred and eight can be done, but pay attention to the fact that Weigang may be incompatible with the previous (in fact, gold also often appears) buy 1G if it is incompatible, don't do it before.

Kingston's quality is relatively better, but the compatibility is not so good** and it is more expensive.

ADATA Apacer is still relatively cost-effective, and the compatibility is also relatively good, and Hyundai doesn't know much about it.

How can you buy DDR400 on your desktop, which is too low, now at least DDR2 800, and DDR400 is still quite expensive, basically it has been discontinued, and it is not convenient for you to change it or others in the future.

Samsung's is better, but ** more expensive. I was using ADATA myself because I was in a hurry to buy it in the store. In fact, Kingston, ADATA, and Samsung are all about the same. ~

1G400 350 or so.

Ranking doesn't make sense, taking into account the problem of fakes.

My desktop wants to buy a memory module.

How do you choose? Let me give you a detailed introduction to the method of selecting a memory module for desktop computers! Hope it helps!

Method 1 for desktop memory module selection.

Look at the type of DDR supported by the motherboard, that is, whether the motherboard supports DDR or DDR2 or DDR3, in terms of time, the most recent.

The computers bought in the second or third year are DDR3, if it is an old computer, you have to check the motherboard model.

Check the frequencies supported by the motherboard for DDR, and the higher the frequency band supported, the better.

Check the maximum memory capacity supported by the motherboard, it is a waste to exceed the memory capacity supported by the motherboard.

If the capacity is expanded on the basis of the original memory, then you must buy the same model of memory, otherwise the compatibility is poor.

Method 2 for desktop memory module selection.

Desktop memory upgrade, to choose the right memory upgrade, firstly, you must choose a memory module that conforms to the motherboard memory slot, if: DDR3 or DDR2, etc., secondly, buy a memory module according to the highest frequency supported by the motherboard, of course, if your motherboard only supports DDR3 1333 memory module, you can also install DDR3 1666 memory module when you buy it, but it can only run the frequency of 1333;

Finally, pay attention to whether the newly purchased memory module is compatible with the original one; The reason is that memory modules of different brands and different chips may produce blue screens due to incompatibility.

crashes and other phenomena.

Therefore, the most perfect choice for desktop memory upgrades is: the same brand, the same chipset.

Memory of the same frequency and capacity. Of course, if your original memory is too small, you can also directly replace the larger memory, as long as it meets the above requirements.

Note: According to your configuration, your motherboard only supports DDR2 memory, the frequency of the motherboard supports memory up to 800MHz, the most common on the market is 1G and 2G memory modules, it is recommended to directly replace two 2G Kingston DDR2 800 memory modules, each on the market **more than 100.

Desktop selection of memory module method three.

Kingston 2GB DDR2 800 190

DDR2 type with 800M is fine.

The reduction of memory is related to the graphics card, and the less memory is used as video memory by the graphics card.

I used it. Your graphics card is 512M, which is the size after adding the shared memory module, and the memory of the graphics card itself cannot reach 512. JS also often uses this to fool us, which is why there is graphics card memory.

Very high, but very low.

There are no parameters for memory other than size and frequency. Nothing else needs to be considered. There are not so many models, and you just say that you want the Kingston 2GB DDR2 800.

Three years ago, memory was very cheap, and in 2008, people speculated on memory, and they just fried it. At that time, the money was at its most expensive, and it was 320. It's about 180 now. This ** has been around for a long time. No one dares to say that it will be high.

Low. The change is only three or five pieces, which has little impact on us.

Mainly to improve the speed of the software, it does not store data for a long time.

Hard drives can be stored for a long time. Probably compare:

Memory hard disk.

The speed is fast and slow.

The capacity is small and large.

Long-term storage is not possible Yes.

Memory plays a big role in a computer, all the programs running in the computer need to go through the memory to execute, if the execution of a large number of programs or a lot, it will cause the memory to be exhausted.

In order to solve this problem, virtual memory technology is used in Windows, that is, a part of the hard disk space is used as memory, and when the memory is occupied, the computer will automatically call the hard disk to act as memory to relieve the tension of memory.

For example, if the computer only has 128MB of physical memory, when reading a file with a capacity of 200MB, it must use a relatively large amount of virtual memory, and the file will be stored in the virtual memory after being read by memory.

After waiting for the memory to store all the files in the virtual memory, the files stored in the virtual memory will be released to the original installation directory.

The function of memory modules: The CPU is an important component of CPU work and is indispensable for reading and writing operations through the bus.

The data written to RAM (i.e., read-write memory, i.e., memory modules) will disappear completely after the power is off, and the earliest program data that the CPU reads and executes when the computer is turned on comes from ROM (read-only memory).

Memory is an essential part of a computer, and the CPU can address it via a 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.

Memory is one of the most important components in a computer, and it communicates with the CPU'Bridge. The running of all programs in the computer takes place in memory, so the performance of the memory has a very large impact on the computer.

Memory, also known as internal memory, is used to temporarily store computing data in the CPU and exchange data with external memory such as hard disks. As long as the computer is running.

The CPU will transfer the data that needs to be calculated to the memory for calculation, and when the operation is completed, the CPU will send the result out, and the operation of the memory also determines the stable operation of the computer. Memory is made up of parts such as memory chips, circuit boards, gold fingers, etc.

Is a desktop computer's memory module running memory or body memory? In fact, many white friends may not be very clear about this problem, so let's find out together.

1. The memory module of the desktop computer is the running memory. The body memory of a desktop computer is a hard disk. The capacity of the memory module is generally 4G, 8G, 16G and 32G, etc., while the capacity of the hard disk is generally 500G, 1T, 2T, 4T and 8T, etc., so the memory module cannot meet the large-capacity needs of the fuselage memory, and can only be used as running memory.

2. The software will run faster after adding more memory. A memory module is an internal memory that directly exchanges data with the CPU, it can be read and written at any time, and it is fast, usually as a temporary data storage medium for the operating system or other running programs. Because the data required for software operation needs to be called into the memory module first, after adding the memory, more data can be called in, which reduces the waiting time of the CPU and accelerates the software operation.

That's all there is to know if a desktop computer's memory module is running memory or body memory.
