Many friends are ready to put in some memory sticks to upgrade their computers. After all, the memory module is not well chosen, the game is stuck as a dog, and it is easy to attract teammates to scold!So the question is, do you really know how to buy a memory module?
1. What is memory?
Memory, also referred to as memory, is called "internal memory" if it is professional, and it is a place where data is temporarily stored while the computer is running.
There is memory, and there is naturally external memory, and external memory is all kinds of external accessories such as hard disks and tapes of the computer. The specific difference is that the memory generally bears the responsibility of temporarily storing things, for example, the computer suddenly loses power halfway through PPT, and the APP is not automatically saved, so this PPT is gone.
All programs in the computer are run in memory, including the computer system, after startup, they are all running in memory, when the program is not running, it is the data in the hard disk, and the program becomes a process running in memory. All applications and games run in memory after launch. The biggest disadvantage of memory is volatility, that is, the data in the memory is gone after a power failure, so when working with files, Ctrl+S (Save) is your essential skill. However, external memory, such as hard disks, optical discs, USB flash drives, etc., can still save data after power failure, so the choice of memory has a great impact on the running speed and stability of the computer.
So, what do you need to know about choosing memory?We can start from both the parameters and the brand.
2. Common parameters
1. Memory capacity
That is, the storage capacity of the memory module, when running the program, it will occupy a certain amount of memory capacity, when the memory capacity usage is too high, it will cause the computer to freeze or even crash. At present, the capacity of memory modules is 2 4 8 16 32 64GB, etc., of which 8GB 16GB 32GB is the current mainstream, and 2GB memory is used less.
2. Memory frequency
It refers to the highest working frequency that the memory can reach, representing the speed of the memory, the higher the memory frequency, the faster the data exchange speed between the CPU and the memory. The mainstream D4 memory frequencies are 3200MHz and 3600MHz. The mainstream D5 memory frequencies are 6000MHz and 6400MHz
In the case that the motherboard does not support overclocking, the choice of memory frequency depends on the lowest frequency of both the CPU and the motherboard. In the case that the motherboard supports overclocking, the choice of memory frequency depends on the highest frequency of the motherboard.
Currently, the motherboards that support memory overclocking are Intel's B, Z, and X seriesAMD's A-series, B-series, X-series.
3. Memory type
DDR3 is only possible on older computers, so here we mainly introduce DDR4 and DDR5.
At present, there are Z690 motherboards equipped with DDR4 memory and Z690 motherboards equipped with DDR5 memory on the market at the same time, and the 13th generation Core still supports DDR4 memory, so the coexistence of DDR4 memory and DDR5 memory will continue for a considerable period of time, but DDR5 memory With the iterative update of technology, the comprehensive performance of DDR5 of many large manufacturers has been gradually improved, whether it is transmission speed or compatibility, it is far from being comparable to some DDR4.
So, my final point is: choose DDR4 memory if you have a limited budget, and choose the top DDR5 if you want the most performance, such as this.
4. Number of memory (dual channels).
Dual-channel is more efficient and faster than single-channel, for example, for the same 16G, two 8GB dual-channel memory will be faster than one 16GB single-channel memory stick. It can be understood as two roads, dual-channel memory modules, the CPU can exchange data through the two roads and the memory, so that the memory bandwidth is also doubled, which is equivalent to the data access speed is also doubled.
Single 16G: It is easy to troubleshoot when there is a problem with the memory module, which is low, but the work efficiency is low.
Dual-root 8G: two at the same time to accept instructions, high efficiency, strong stability, one has problems, the other can be used normally, but it is also prone to compatibility problems, such as two plugged into the motherboard alone, plugged into the motherboard at the same time can not be lit.
5. Memory particles
Let's talk about memory particles first, the three most influential memory particle manufacturers are Samsung, Hynix, Micron, in addition to our domestic memory particles, Changxin, Ziguang, Nanya, etc. are also good. Among them, Samsung and Hynix are both big brands in South Korea and have a greater say in flash memory particles. Theoretically, the better the memory grain, the more stable it is, the higher the voltage it can withstand, and the greater the potential for overclocking.
3. Memory brand
Our more common and reliable brands are: Lexar, Kingston, ADATA, Samsung, G.SKILL (G.).SKILL), Corsair, TEAMGROUP, Micron Crucial, KLEVV, ASGARD, Gloway, Shadowrace, Golden Baida, etc. (In no particular order and not only these, but these are enough for everyone's reference) so many brands, how do we choose the right one?
First of all, there is no first, the same is true for memory brands, there is no absolutely perfect memory brand, due to the difference in these factors, particles, capacity, frequency, appearance, etc., resulting in the cost performance of each product is not the same, relatively speaking, the shipment is large, the name is relatively loud, basically it is not a big problem. Everyone is no stranger to Lexar, and they are also veteran players in the storage track, and the choice of such a big brand is also guaranteed by after-sales and service.
Fourth, memory product recommendation
After talking about so many dry goods, it is estimated that many people can also see it in a fog. After all, the particles and channels are too abstract for us people, and there is no way to concretize them in our minds. Now I recommend some memory modules that you can't go wrong with your eyes closed.
1、ddr4
1.Golden Baida Silver Lord
The first is the Changxin particle version of the Jinbaida Silver Jue, 3200 frequency C14 has strong performance at the same price, which can exceed 4000 frequency, but the timing performance after overclocking is relatively average, in general, the budget is not much, and you can choose this one with certain requirements for performance.
In addition, the compatibility of Changxin particles on the motherboard is relatively general, you can ask customer service before buying, or check the memory compatibility table on the official website of the motherboard, if you are not compatible, you can choose the version of Hynix particles, the timing performance is weaker, but the compatibility is better.
2.ASGARD TUF co-branding
The second is the ASGARD TUFF co-branded model. You can also choose domestic Changxin's particles, which are a little more expensive than Jinbaida, and the performance is about the same, but the materials and appearance design are better, and you can choose this if you like a black vest.
3.Acer Marauder Glare Starship
This is one of the ceilings of the current DDR4, which is also a special Samsung B-die, and the 3600 frequency is pressed to C14 timing, with 10 layers of PCB, high-quality aluminum alloy vest, overclocking potential and life are guaranteed, and the lighting effect is also very good-looking, suitable for players who assemble high-end game consoles.
But then again, for gamers who haven't decided on a CPU motherboard yet, DDR5 is more appropriate at this price point.
2、dd5
1.Guangwei Shence
This is Guangwei's flagship series, the overall appearance is very high, and the material is very fierce, aluminum heat dissipation vest, copper vapor chamber, 10-layer PCB, with high-quality Hynix A-Die particles, with excellent heat dissipation and overclocking potential, but the brand is average.
2.Asgard Blowing Snow Collaboration
Although the two-dimensional co-branding looks like it has a feeling of paying taxes, in fact, this co-branding is very cost-effective, Hynix A-Die particles, 6800 frequency C34 timing, you can consider the group of small blowing snow hosts.
3.Lexar DDR5 Esports Ares God of War Blade
The use of all-aluminum pure white heat sink + high thermal conductivity glue, which can quickly export memory heat, and the mecha-style appearance design should meet the taste of many gamers. At the same time, it supports four lighting effects such as ASUS and Gigabyte, and the specific color can be adjusted by the next app. The 32GB package consists of two single 16GB memory, each with a single-sided 8-particle design.
The particles are made of the well-known Hynix A-Die particles, which have good overclocking capabilities, basically more than 7000, support RGB synchronization, and support Intel XMP 30 and AMD Expo dual-platform one-click overclocking configuration, in the DDR5 high-frequency bar, the timing is lower, so it has better memory latency performance, which is the answer of the version at the same price.
These mentioned above are basically more recommended, if you insist on the main promotion, I personally recommend Lexar DDR5 E-sports ares God of War Blade, after all, the first echelon of cost performance is there. Of course, turnip greens have their own favorites, so everyone can start according to their needs.
