内存要双条8g的还是16g的(笔记本单条16g内存与双条8g)

Dual 8GB memory modules are better.

First of all, the advantage of a single 16GB memory stick is that it is more convenient for future upgrades and expandability. The dual 8GB memory modules form dual channels, which improves performance by nearly 5%. This is the main reason why many people choose dual 8GB memory modules for dual channels. Of course, this is also in line with our original intention when assembling the host. If we want strong performance, dual 8GB memory modules are a small way to improve system performance. .

Although the advantages of dual 8GB memory modules are obvious, the shortcomings are also fatal. Although the single 16GB memory module does not have dual channels, this is something you want to upgrade in the future. At that time, you only need to buy another 16GB memory stick with the same frequency and the same brand. When upgrading, all the dual 8GB memory modules need to be eliminated and replaced with new ones, which will consume a lot of your budget for future upgrades.

Therefore, it is recommended that if you want to choose dual channel and do not plan to update or upgrade the hardware for a long time, choosing dual 16GB memory modules is the best choice, so that there is no room for upgrades in the future. The performance of the system can also be further improved.

If you can choose computer memory sticks and your computer has two memory card slots, you will usually choose two 8G memory sticks instead of one 16G memory stick. Of course, if If he had sufficient funds, wouldn't it be better to install two 16G memory sticks? The premise is that the computer's motherboard memory card slot supports up to 16G memory sticks. Some computers support up to 8G, so it can only hold two 8G memory sticks.

The total increased memory capacity is also 16G, but why choose two 8G memory? Because two memory sticks are placed on two card slots, this information is a two-way channel. That is to say, the computer can receive and process information at the same time, and then transmit the information out at the same time. One is the channel for incoming information, and the other is the channel for outgoing information. Its speed will be faster, and the number of 16G running memory, it It is equivalent to a large room. But no matter how big the room is, the door is so big. If someone comes in, they can't go out, otherwise they will bump into each other.

To use a popular metaphor, a 16G memory stick is equivalent to a 100-square-meter room, but it has only one door. If someone comes in, they can only come in, and if someone leaves, they can only go out. Even if the time occupied by this door is very short, it also affects performance. Two 8G memory sticks are equivalent to two 50-square-meter rooms. They are two doors, one for input information and one for output information, and these two The information of each memory stick is common. Because it is in front of a computer, its response speed is relatively faster.

If your computer itself supports the highest operation and the memory is adjusted to level 16 and you install two 16G memory sticks, the effect will definitely be better, but the price may be more expensive, and then two 8G memory sticks Its total price is on average 20% to 40% more expensive than 16g running memory, but even so, the price is reasonable, and most people will still choose to install two 8G running memory.

There is a big gap between single 16g and double 8g.

Comparison between two 8G memories and a single 16G memory. When the performance parameters are consistent, two 8G memories can build dual channels. With the support of dual channels, two 8Gs are equivalent to twice the memory bandwidth for the computer. When the computer only has an integrated graphics card, memory needs to be used as video memory. If there is dual-channel memory, the computer graphics display will be smoother. A single 16G memory cannot play this role.

Under normal use, the probability of failure of a single 8G memory and a single 16G memory is the same. If a single 16G line fails, the computer will immediately become unusable. If any one of the two 8G memories is broken, the other one can continue to ensure the normal operation of the computer, and the fault tolerance rate is obviously higher than that of a single 16G memory.

The role of the memory stick

The memory stick, also referred to as memory, is an important part of the computer for temporarily storing computing data. The memory is like a desktop, and the hard disk is like a drawer for storing items. When you need to process data, you need to take the items out of the drawer and put them on the desktop for processing. After the processing is completed, put them back into the drawer for storage. The role of the memory is temporary. A medium for storing and computing data.

When the memory capacity of the computer is only 2GB, and the opened file needs to occupy close to 2GB or even exceeds 2GB, the computer will run very slowly, and may even freeze. At this time, Need to replace the memory module with a larger capacity.
