How to check the DDR number of laptop memory module

How to check the ddr value of a computer memory stick

The method to check the ddr value of a computer memory stick is as follows: If it is a single memory stick, it is not installed in the computer. , judge based on the model number indicated on the label of the memory stick: 3200, 4300, 5300, and 6400 are all DDR2 generation memories. Those below this range are one generation; those above this range are generally three generations.

, install driver wizard, Master Lu and other software; 2. Double-click to run the software (taking Master Lu as an example), click "Hardware Detection"; 3. View it in "Memory Information".

View instructions. If it is a brand-name computer, it will usually come with a computer manual or a detailed hardware configuration list, from which the memory model can be determined. Check the actual memory.

If there is no label on the memory stick, or the writing on the label is difficult to read, you can tell which generation of memory it is by counting the gold fingers on the memory stick: 92 × 2 (92 gold fingers on both sides) is DDR1 Memory; 120×2 is DDR2 memory. The above refers to desktop memory modules.

Open the computer and click search in the lower left corner, enter CMD in the search, and then hit enter, as shown in the figure below. Enter the command "wmic" and press Enter. Then enter the command "memorychip" to see the frequency of the memory module.

Method 1: Use hardware detection software to check the notebook memory module model (recommended) There are many computer hardware detection software, including Master Lu, Driver Wizard, CPU-Z, etc. Generally, the author prefers to use Master Lu to check the computer Hardware, the following is a brief introduction to how to use Master Lu to check the memory model of a notebook.

How to distinguish between 1st generation, 2nd generation and 3rd generation notebook memory modules

1. PC2 and pc3 represent the generations of memory. PC2 is the second generation memory and pc3 is the third generation memory. Steps to check the generations of notebook memory modules: Check the manual. If it is a brand-name computer, it will usually come with a computer manual or a detailed hardware configuration list, from which the memory model can be determined. Check the actual memory.

2. There are three basic methods to check the generation of the memory module: Check the manual: If it is a brand computer, it will usually come with a computer manual or a detailed hardware configuration list, from which the memory model can be determined.

3. Check the memory module model displayed on the page. If the displayed type is DDR4, it is a fourth-generation memory module; if the displayed type is DDR3, it is a third-generation memory module; if the displayed type is DDR2, It is a second generation memory stick.

4, 4300, 5300, 6400 are all DDR2 generation memory. Those below this range are one generation, and those above this range are generally three generations.

5. How to distinguish DDR, DDRDDR3 and DDR4 memory from appearance. The quick identification method of DDR1 generation memory, DDR2 generation memory, DDR3 generation memory is as follows: red box memory stick, DDR1 generation is a blockbuster, DDR2 and DDR3 are Small pieces.

1. Both DDR2 and DDR3 memory use FBGA (bottom ball pin package) packaging technology , compared with TSOP, the memory particles are much smaller, and the FBGA packaging form has obvious advantages in anti-interference and heat dissipation.

2. DDR2 800 is the second generation. DDR3 is the third generation.

3. Question 1: How to distinguish the generation of a memory stick. If you look at the appearance, you must look at the U-shaped card slot of the memory. DDR is the first generation, DDR2 is the second generation, DDR3 is the third generation. Question 2: How to tell the generation of a computer memory stick? Use Master Lu to determine your hardware model.

4. The position of the notch of each generation of memory is different: The biggest difference of DDR4 is that the gold finger at the bottom is no longer straight, but curved.
