Why is the DDR memory clock frequency not the maximum?

The true clock frequency of 267 MHz (DDR) is the frequency at which the hardware is running, while the so-called "effective clock frequency" is the frequency at which the previous generation of SDRAM (e.g., PC133 SDRAM) operates. In the previous generation, memory only transmitted data on the rising edge of the clock, and not on the falling edge. The DDR generation transmits data on both the rising and falling edges, so it is equivalent to twice the performance of the previous generation.

Real clock frequency 267 MHz (DDR) = effective clock frequency 533 MHz, got it?

DDR dual data rate, double transmission rate, so the real frequency is 267, valid 267 2 533

If you don't have the same frequency of two RAMs, it will use your low one, or your motherboard won't support the high one, and it will come down for you. ``

The memory clock is a very important parameter in the memory module, which indicates the highest frequency at which the memory module can work. In computers, memory clocks are usually expressed in mhz. For example, if the memory clock is 3200MHz, then the maximum operating frequency of this memory module is 3200MHz.

Memory frequency is closely related to the memory clock, which refers to the amount of data that a memory module can transfer per second. The unit of memory frequency is usually mt s, which is millions of transfers per second. For example, the DDR4-3200 memory has a frequency of 3200 mts, which means that data can be transferred 32 million times per second.

The relationship between memory clock and memory frequency can be calculated by the formula: memory frequency = memory clock 2 number of transmission channels.

In order to increase the memory transfer speed, memory manufacturers increase the memory frequency by increasing the frequency of the memory clock. However, the higher the memory clock and memory frequency, the better, because the increase of the memory clock and memory frequency will lead to increased memory heating, decreased stability, and even lead to problems such as computer crashes. Therefore, when choosing a memory module, you need to choose the appropriate memory clock and memory frequency according to your own needs and computer configuration.

In addition, the impact of increasing the memory clock and the memory frequency on the performance of the computer is not linearly increasing, and the increase of the memory clock and memory frequency is decreasing on the performance of the computer. Therefore, when choosing a memory clock and memory frequency, you need to choose a memory module with a higher cost performance according to your own needs.

Memory clock and memory frequency are the two core parameters of memory. The memory clock refers to the clock frequency of the memory controller, which is the time it takes for the memory to read and write data. Memory frequency refers to the frequency at which a memory module is working with a destructive frequency, which is twice as fast as the memory clock.

The higher the memory clock and frequency, the faster the read and write speed of the reboot memory, but it also leads to an increase in energy consumption and fiber mold heat. Therefore, we need to make appropriate choices according to actual needs to get better performance and stability.
