DDR PC 1600 indicates at what clock frequency it is operating.

DDR transmission standard.

Standard DDR SDRAM is divided into DDR 200, DDR 266, DDR 333 and DDR 400, its standard operating frequency is 100MHz, 133MHz, 166MHz and 200MHz respectively, the corresponding memory transfer bandwidth is , , and, non-standard DDR 433, DDR 500 and so on. Beginners are often confused by the words DDR 266, PC 2100 and so on, here I want to explain that DDR 266 and PC 2100 are actually the same thing, but the way of expression is different. DDR 266 refers to the operating frequency of this memory (the actual operating frequency is 133MHz, which is equivalent to 266MHz of SDRAM), while the PC 2100 refers to its memory transfer bandwidth (2100MB sec).

In the same way, PC 1600 is DDR 200, PC 2700 is DDR 333, and PC 3200 is DDR 400.

Indicates that the memory working frequency is 100-200MHz

In the case of both CPU and motherboard support, the higher the memory frequency, the better.

The higher the memory frequency, the faster the data exchange with the CPU, and the faster the overall speed of the computer.

There are regulations, and the frequency of memory modules used by different motherboards is different. The most commonly used memory module today is DDR1 and DDR2 have different frequencies.

The 256M x16 is 16 256 memory chips, consisting of 4G memory.

PC1600 is the clock frequency.

K4B4G1646B-HCK0 is a memory model, and it is generally useless to see him.

The 256M x16 is 16 256 megabytes of memory, which is embedded in a memory module and should have a capacity of 4GB of RAM.

PC1600 is the clock frequency of the memory bus and the memory model, the correspondence: 100MHz-PC1600,, 133MHz-PC2100, 166MHz-PC2700, 200MHz-PC3200, 233MHz-PC3700, 266MHz-PC4200, correspondingly, each of the above memory models runs under the following effective clock frequencies: 200MHz, 266MHz, 333MHz, 400MHz, 466MHz and 533MHz.

k4b4g1646b-hck0 said: It should be the model specifications of Samsung's factory,I don't know very much,The middle paragraph can be guessed,But it's not absolutely accurate,4G=4G memory,I really don't understand。

256M x16 is 16 256 memory chips, composed of 4G memory, PC1600 is the clock frequency.

If explained, there are very complicated arguments.

In the vernacular, DDR3 1600 is the speed at which the memory runs The higher the speed, the faster the memory theoretically.

The operating frequency of 1600 memory is 800 megahertz seconds, and 1600 is the speed at which data is processed, like the diameter of a water pipe

Some motherboards have a bandwidth of 1600, and with 1600 memory, they can work perfectly. The diameter of the motherboard water pipe = the diameter of the memory water pipe.

If the motherboard bandwidth is 1066 and the memory is 1600, then the memory capacity is not fully played.

1600 represents the memory frequency, the higher the frequency, the faster the memory calculation, the better the memory, and the higher the **. 1600 is greater than 1333, that is, the memory with a frequency of 1600 is faster than 1333.

1600MHz frequency, the larger the access speed.

Brand & Memory Granules!! If it's performance, it depends on its frequency, memory particles!!

Memory particles, the quality of memory particles determines the main factor of the overall quality of the memory PCB board layer, a good PCB can make the memory play a high performance, especially at high frequency, anti-magnetic interference, etc., generally 4 layers, the more layers, the better, but then doubled, clock frequency, the most common DDR2 800 is the mainstream product we buy, the system can exceed 1066 or even higher memory quality, you can feel it when you use it, such as Suddenly blue screen, crash, Data often conflicts, If you can't read and write, etc., it's a poor performance of memory, and the new memory will be baked for 5 hours, if it's okay, it's basically okay.

There's no need to think about this, don't buy Kingston's, that thing is not good, I never give Anjin Xianxingston when I install the machine for my buddies, I give them An's rent Ling Jinbang ruined the shape, that is good.

1. Storage capacity: that is, the amount of binary information that can be held by a memory module, such as the storage capacity of the commonly used 168-line memory module is generally 32 megabytes, 64 trillion and 128 megabytes. DDRII3 is generally 1GB to 8GB.

2. Access speed (storage cycle): that is, the shortest time required between two independent access operations, also known as storage cycle, the access cycle of semiconductor memory is generally 60 nanoseconds to 100 nanoseconds.

3. Reliability of memory: The reliability of memory is measured by the mean time between failures, which can be understood as the average time interval between two failures.

4. Performance ratio: performance mainly includes memory capacity, storage cycle and reliability, and the performance ratio is a comprehensive index, which has different requirements for different memory.

Tools: Computer, memory detection software.

Steps: 1. Install the software memtest to detect the memory.

2. Double-click the memtest software and click Confirm.

3. Enter the main test window and click the Start Testing button to start testing the memory.

4. After that, it will prompt that the memory module on the computer will be detected, if there is any memory problem, it will be prompted, and you can stop the memory test at any time, click the "OK" button to continue.

5. After that, you can see that there is a number changing at the bottom left of the window, which is the percentage of the current memory test process. In addition, the number in front of errors represents the count of memory problems, 0 means normal, if there is a number, it means that there must be a memory problem.

This is physically difficult to see, generally you have to get on the machine to know whether it is good or bad, but from the appearance of the gold finger at least is intact, there is no defect, the SMD components are not soldered, but this must have a certain foundation to see.

You can use some memory detection tools to detect its size, such as cpu-z, this detection tool is good, you can try it, the larger the general memory capacity, the better, you can also open some large-capacity programs to try it, to see the response speed of the machine!

In appearance, only look at his brand and memory particles; You can use the software to test his specific metrics.
