Can memories with different frequencies be mixed?

With the development of computer technology, people’s demand for memory is increasing day by day. Sometimes we will encounter such a situation: our computer memory is not enough, and we want to add a new memory stick, but we only have one memory stick at hand, and the frequency of the memory stick is different from the existing memory stick. In this case, can we mix memory modules with different frequencies?

First, let us understand the frequency of the memory module. The frequency of a memory stick refers to its transmission speed, that is, the speed at which the memory can transmit data. Common memory frequencies include DDR4 2133 MHz, DDR4 2400 MHz, etc. In addition, when selecting memory modules, we also need to pay attention to the type, capacity and timing of the memory modules.

In fact, it is possible to mix memory modules with different frequencies. However, the mixed use of memory modules with different frequencies will limit the running speed of the memory, and the performance of the entire memory system will also be reduced. This is because the memory controller will operate at a lower frequency to accommodate the speed of all memory modules.

For example, if our computer has installed a memory stick with a frequency of DDR4 2400 MHz, and we insert another memory stick with a frequency of DDR4 2133 MHz, then the frequency of the entire memory system will be It will be adjusted to 2133 MHz, matching lower frequency memory modules. As a result, the original DDR4 2400 MHz memory stick can only work at a speed of 2133 MHz and cannot exert its full power.

In addition, mixed memory modules may also cause compatibility issues. In some cases, memory modules with different frequencies may not work properly at the same time on the same computer. Therefore, before mixing memory modules, we need to confirm their compatibility, and it is also recommended to choose memory modules with the same frequency for mixed insertion.

But we don’t have to worry too much, especially in actual use, the impact of mixed memory modules is not particularly obvious. For most ordinary users, a single-frequency memory stick is enough to meet daily needs. Unless we are advanced users who have high requirements for computer performance, we will really feel the performance degradation caused by frequency inconsistency.

In summary, memory modules with different frequencies can be mixed and used, but this may cause performance degradation and compatibility issues. If we want to give full play to the performance of the memory, it is best to choose memory modules with the same frequency to combine. Otherwise, memory sticks with inconsistent frequencies can be used normally, but the running speed of the entire memory system will be limited.
