How to choose the right computer memory stick

How to choose the appropriate computer memory stick: 1. Choose the memory capacity suitable for the CPU and motherboard; 2. Choose the memory generation with the higher the frequency and the faster it runs; 3. Choose the memory frequency and effectiveness High; 4. Select dual memory channels.

How to choose a suitable computer memory module:

1. Memory capacity

About Many friends have misunderstandings about memory capacity. Is the bigger the memory, the better? In fact, the size of the memory also needs to consider the CPU and the motherboard. Currently, the mainstream motherboard supports up to 64G of memory, and the maximum memory supported by the 64-bit CPU is 128G. So the memory If it exceeds the 64G of the motherboard, it has no meaning.

At present, the mainstream memory includes 4G, 8G, and 16G single sticks. If you want to obtain higher memory, you need to add more memory sticks. It depends on how many memory card slots your computer has. And we are choosing the memory. When purchasing memory modules, try to choose memory modules of the same brand and frequency to avoid incompatibility that may cause the computer to fail to boot.

2. Memory generation

The memory generation refers to "DDR1", "DDR2", "DDR3", and "DDR4" in the memory name. At present, the mainstream platforms have been upgraded to DDR4. The technology from DDR1 to DDR4 is more advanced, the higher the frequency, the faster it runs.

Then the settings of memory card slots are different for different generations. DDR2 fool-proof slot design is in the middle, DDR3 is on the left, and DDR4 is on the right. When purchasing memory, you must know which generation your computer's memory card slot supports before placing an order, so as not to buy it inappropriately.

3. Memory frequency and timing

Simply put, the frequency of memory is like the valve of a faucet. The bigger you open it, the faster the water comes out. So with the same capacity of memory, the memory The higher the frequency, the better the performance. This is why high-frequency memory is more expensive.

Then the common frequencies of memory frequencies from 1st generation to 4th generation are as follows:

• The main frequencies of DDR memory: 200 Mhz, 266 Mhz, 333 Mhz, 400Mhz

• DDR2 memory main frequencies: 400Mhz, 533 Mhz, 667 Mhz, 800 Mhz, 1066 Mhz

• DDR3 memory main frequencies: 1333 Mhz, 1600 Mhz Wait

• DDR4 memory 2133MHz, 2400 MHz, 2800 MHz, 3200 MHz

Timing refers to the delay time of the memory, timing at the same frequency The lower the better!

4. Memory channel

Memory channel is divided into single channel and dual channel. Single channel means that it can only read or write at the same time, just like a toll station only has Only one vehicle can pass through a channel, so only one vehicle can pass in and out. Dual-channel means that memory reading and writing use different channels, which can be read and written at the same time. The memory bandwidth is doubled, just like the toll station has separate entrances and exits, so that you can enter and exit at the same time, improving efficiency.

Dual-channel memory is a technology that can improve computer performance. To put it bluntly, the two memories are improved from series to parallel in order to obtain greater memory bandwidth and thereby increase memory speed. When the computer memory is insufficient, you can solve the problem of insufficient memory by adding memory and setting up dual channels.

5. Look at the brand. The

brand's memory sticks are of excellent quality and have good after-sales service, so they should be given priority. Generally, you can trust the big brands, but you must go to a regular digital store or repair point to buy to prevent being scammed.

6. Check the warranty period.

Different brands of memory modules have different warranty periods. Please ask carefully when purchasing to avoid running into trouble. If you are worried, you can mark the date on the memory stick.

7. Look at the workmanship.

Memory sticks are relatively sophisticated things, and the workmanship should be more meticulous. If the workmanship is rough, the quality of the memory stick is often poor, and it is not recommended to purchase and use it.

8. Carefully check the anti-counterfeiting label

The anti-counterfeiting label of the memory stick can very well identify the authenticity of the memory stick. If you don’t know how to read it, you can ask someone who knows how to choose it for you. , to avoid buying fake products.

9. Be optimistic about the type of memory module

You must choose the appropriate one according to the type of memory module of your computer, otherwise you cannot use the memory module. For example, it depends on whether your memory module is DDR, DDR2 or DDR3. DDR3 has a lower operating voltage than DDR2, from 1.8V of DDR2 to 1.5V, which has better performance and saves power; DDR2’s 4bit pre-read upgrade Read ahead for 8bit.
