不同容量的内存混插(内存大小不同可不可以混插)

1. Memory modules of the same type and different capacities can be mixed. For example, DDR3
2GB and DDR3
4GB ​​can be mixed.
2. Different frequencies of the same type can be mixed, but the performance should be reduced to the lowest. For example, if 1600 and 1333 are used together in DDR3, 1600 should be reduced to 1333.
3. Different brands of memory can be mixed
, especially the memory compatibility of famous brands such as Kingston, ADATA, Corsair, Samsung, and Apacer is relatively strong.
4. Theoretically, it can be used if the above conditions are met, but in fact, no matter what is used, it must be tried on the computer.
How can you add more memory to the machine in your hand? Just follow what I said above and buy it.

Can be mixed. Dual channels composed of different capacities are called flexible dual channels.

As long as they are the same generation of memory, memory with different capacities, different timings, different brands and different frequencies are also compatible, and it is possible to set up dual channels, and the timing and frequency will automatically be reduced to the lowest memory.

In practice, when increasing computer memory, try to choose memory of the same brand and model, and install them together to achieve the purpose of increasing computer speed and running safely and stably. Whether memory modules can be mixed depends not on the memory brand, but whether the motherboard supports memory mixing. As long as the motherboard can be installed, the memory can theoretically be installed together and used.

Extended information

When memories with different frequencies are mixed, the two memories will be adjusted to run at the same frequency, that is to say, one with a higher frequency A low frequency will run at the lowest frequency. If the original memory is relatively high, it will reduce its performance.

There are some compatibility issues between memory and motherboards. For example, some motherboards can only use DDR31333 memory, but will not recognize it after plugging in DDR1600 memory. It is best for the memory chips to be the same, preferably the same brand of memory, otherwise there may be incompatibility, instability, or even unrecognizability problems.

Memories with the same interface have different capacities and can be mixed, but it is not recommended.
In fact, when the memory is mixed, as long as the same interface is used, the capacity, brand and frequency can be different. Only when the frequencies are inconsistent, all memories will run at the memory parameter with the lowest frequency. Note that DDR3 memory has two types: standard voltage and low voltage, and cannot be mixed.
You can use two memory sticks of different sizes. Two memory sticks of different sizes form an asymmetric dual channel. The efficiency of an asymmetric dual channel is still higher than that of a single memory stick. But it is still not as efficient as a dual-channel composed of two memory sticks of the same size. When two memory sticks of different sizes form a dual channel, the part of the memory stick of the same size will form a normal dual channel, while the remaining part will still operate as a single channel. In this asymmetric dual channel memory mode, the system will It is preferred to use the dual-channel mode, and the single-channel memory part will only be called when the memory demand is too large. In today's computer hardware, even if memory modules of different frequencies or different sizes are mixed, the memory modules are generally compatible. The combination of hardware is not as demanding as in the past. However, such mixing will often affect the performance of the hardware. It is best to use the same Frequency and memory modules of the same size are used in combination.

No problem. However, incompatibility cannot be ruled out, but even if two memory sticks of the same model and size are used, incompatibility will still exist.
As long as they are of the same generation and voltage, there is no impact on the selection. Even if the memory frequencies are different, the memory with a higher frequency will automatically be reduced to a memory with a lower frequency to form a dual channel. For example, if one channel is 2GDDR31333 and the other is 4GDDR31600, the DDR31600 will be reduced to 1333, but the total memory will remain unchanged at 6G.
Notes on mixed memory insertion:
1. Do not mix different types of memory. Generally speaking, there are large differences in the working voltage of different types of memory, and this value is much higher than the endurance of the memory itself. Moreover, the electrical interfaces of different types of memory are also very different, so different types of memory cannot be used. Mixed penetration.
Even if the motherboard provides two or more different types of memory slots, unless the motherboard has special settings, if different types of memory are mixed, the memory may be damaged due to various factors such as voltage. It will shorten the service life of the memory and even cause the memory to be burned.
2. Memory of the same type but different voltages cannot be mixed. Even the same model of memory has different voltages. For example, SDRAM has 3.5V and 3.3V. If you mix these two types of memory with different voltages, it will not only cause computer instability, but also accelerate the aging of the low-voltage memory or even burn it out.
