How many generations of memory are there? I ve got several internal storage messes and no labels on

Hello, according to your description, you are wondering how to identify and distinguish memory sticks;

There are many types of memory, and SDRAM memory is the main memory on the market, including: SDRAM, DDR SDRAM, DDR SDRAM, DDR SDRAM;

Their external differences are mainly in the interface, that is, the number and distribution of pins of the gold finger, and the slot types are all DIMM;

Because there is a difference between desktop memory and laptop memory, we have to look at it separately;

Desktop memory modules:

SDRAM uses a working voltage and has 168 pins;

DDR SDRAM operates at 184 pins;

DDR SDRAM memory uses operating voltage and has 240 pins;

DDR SDRAM uses a working voltage with 240 pins, which is different from DDR.

Laptop memory module:

SDRAM has several specifications such as PC66, PC100, PC133, etc.;

DDR SDRAM operates at 200 pins;

DDR SDRAM memory uses operating voltage, with 200 and 240 different ground pins;

DDR SDRAM operates at 200, 204 and 240 different pins;

Supplement: Different generations of memory cannot be interplugged, the interface (number and distribution of gold fingers) is different, and the working voltage is not the same!!

If you have any other questions, please continue to ask

Two notches, single-sided 84-pin, double-sided 168-pin, voltage, memory particle rectangular (obsolete).

1st generation) one notch, single-sided 92-pin, double-sided 184-pin, voltage, memory granular rectangular Operating frequency 266,333,400.

2nd generation) one notch, single-sided 120-pin, double-sided 240-pin, voltage, memory particle square Operating frequency 533,667,800.

3rd generation) one notch, single-sided 120-pin, double-sided 240-pin, voltage, memory granular square Operating frequency 1066, 1333, 1800.

Plug it in and it will be displayed.

Question 1: How to distinguish how many generations of memory modules are If you look at the appearance, you have to look at the U-shaped card slot of the memory.

DDR is the first generation, DDR2 is the second generation, and DDR3 is the third generation.

Question 2: How do you see how many generations of memory your computer uses, and there is a sticker on the memory. See if it's DDR400 or DDR667 or whatever.

Gen memory: DDR333

ddr400

Second-generation memory: DDR667

ddr800

Third-generation memory: DDR1066

ddr1333

Of course, like the 2nd generation, there will also be DDR21066 and the like, but there are relatively few, and they are all relatively high-end memory.

Question 3: How do you see how many generations of memory are the algebra of memory:

The first generation of memory DDR frequency is 266 333 400MHz

The second generation memory DDR2 frequency is 533 667 800MHz

3rd generation memory DDR3 frequency 1066 1333 1600 1866....

You're obviously DDR3 1333MHz, which is the third generation memory frequency 1333.

Question 4: How to look at the current memory dislike and how many generations are generally written on the memory label label, PC2 means 2 generations, PC3 means 3 generations, 4 generations have not been used, it is estimated that it is about the same.

Question 5: How do you see how many generations of memory are DDR, DDR2, DDR3, DDR4 are 1 to 4 generations!

Each generation does not have only one frequency, one generation has waiting, the second generation has waiting, the third generation has waiting, and the fourth generation has very few on the market, and there are so on!

For example, DDR4 2133

Question 6: How do you see how many generations of memory are the RAM with SDRAM DDR1 DDR2 DDR2

Specifically, several generations are generally written on the label on the memory. If not, you can look at the notch. SDRAM is 2 notches, DDR2 and DDR3 are both notched.

But the closer you get to the middle, it's DDR3

Question 7: How do I check the information of the memory module of my computer? How many more generations? CPU-Z, software, or Master Lu! It is recommended to use the software butler in 360 Security Guard**! PC2100 is DDR 266 memory.

PC2700 is DDR 333 memory.

PC3200 is DDR 400 memory.

PC4200 is DDR2 533 memory.

PC4300 is DDR2 533 memory.

PC5300 is DDR2 667 memory book destroyed.

PC6400 is DDR2 800 memory, PC8500 is DDR3 1066 memory.

Question 8: How to see how many generations of Kingston memory sticks are and how big are they Generally, it is written on the memory module, DDR3 is the 3rd generation, the maximum is 8G, and DDR2 is the 2nd generation, the maximum is 4G

Question 9: How do desktop computers look at the memory module for several generations.

Question 10: How do you look at the generations of memory modules Kingston DDR3 1600's third-generation memory modules, with a capacity of 2G, belong to the SP economy bar series.

There are three basic ways to see how many generations a memory module is:

1. Check the manual: If it is a brand computer, it will generally come with a computer manual or a detailed hardware configuration list, which can determine its memory model.

2. Check the physical memory: turn off the power off, open the chassis, check the memory inserted into the memory slot of the motherboard (you can remove the memory for observation, as shown in the figure below), and compare the two to determine its model. Memory appearance distinction diagram:

Mainly compare the number of pins and the notch position on the gold finger, or look at the parameters on the memory tab.

DDR1: One notch, 92 pins on one side, 184 pins on both sides, 52 pins on the left and 40 pins on the right, and a rectangular memory particle.

DDR2: One notch, 120 pins on one side, 240 pins on both sides, 64 pins left, 56 pins on right, memory particle square, voltage.

DDR3: 1 notch, 120 pins on one side, 240 pins on both sides, 72 on the left and 48 on the right, memory particle square, voltage.

3. Software detection of memory: The hardware can be detected through special tools such as 360 driver master, Lu master, driver wizard, etc., to determine the memory model.
