双通道只有一根内存条(双通道必须两根内存么)

When two memory sticks are plugged into the desktop, only one is displayed. This is because the other memory stick is not inserted in place and the computer cannot recognize it normally. The specific repair method is as follows:

1. First, open the computer case and find the location of the memory slot:

2. After inspection, you can see that the right side of the memory module has been detached from the buckle:

3. Then press the memory stick with both hands until you hear a click and the memory stick is in place.

4. Then sort out the connecting cables inside the chassis to avoid The wire is wrapped around the memory module:

5. Finally, close the case. Turn on the power, and the computer will be able to identify the two memory modules:

Extended information:

The memory module socket on the motherboard is for the insertion of memory modules. The memory module is the computer's memory, that is, RAM. Since the size of the running memory affects the running speed of the computer, high-performance computers will be equipped with high-value memory modules.

Due to current technical limitations, the maximum specification of a single memory stick is only 16GB. Therefore, when it was impossible to expand larger RAM storage, a DDR double data rate operating mode was developed, which can be expanded to a maximum of 32GB of operating memory.

First, your computer system may still be a 32-bit system. If it is only a 32-bit operating system, it can only recognize memory up to 4G. Second, your motherboard may not support it. There are certain compatibility issues with the insertion cables for dual memory modules. You can pay attention to the motherboard model and check the relevant information to see if it supports multiple memory modules in parallel. The third is whether your memory module is installed properly. It is possible that the pin is not fully inserted into the memory module slot, resulting in poor contact and inability to read the relevant memory module data.

There are two possible reasons
One is that your memory stick does not meet the requirements. Plug it in (as long as it is plugged into the slot of the same color)
The second is that your cpu-z version is relatively old (my z68 motherboard uses the old cpu-z version and does not display dual channels)
