Průmyslový počítač je jedním z důležitých doplňků v počítači a je mostem pro komunikaci s ním. Používá se hlavně k dočasnému uložení provozních dat v CPU a dat vyměňovaných s jinými externími pamětmi. Protože všechny programy v počítači běží v počítači, má výkon paměti a stabilní provoz počítače velký vliv na počítač.
Many users' understanding of memory remains at the level of "bigger is better". The memory capacity has a great impact on the performance of a machine, especially when running some large programs and multi-window work, the memory capacity is very large. important. However, it is obviously not enough to only focus on the capacity. Here are some issues that should be paid attention to when purchasing memory:
Let's first understand the main structure of the memory. The memory is mainly composed of memory particles, PCB circuit boards, and gold fingers.
Choose the right type
Memory is divided into three different generations of memory: DDR, DDR2 and DDR3. Since the three types of DDR memory are incompatible with each other from memory controllers to memory slots. And even on some Combos that support two types of memory at the same time, the two types of memory cannot work at the same time, and only one of them can be used. Therefore, before buying memory, you must first determine the type of memory supported by yourself. .
Choose Original Granules
The quality of the particles itself has an almost decisive influence on the quality of the memory module. 90 percent of the quality of the memory is determined by the chip.
In the FAB of the international original factory, a qualified silicon wafer must be successfully born after several months of physical, chemical and photoelectric reactions under harsh conditions. After rigorous and fine polymer cutting, only the essence with better performance and quality is retained, and then these selected essences are encapsulated, and finally the encapsulated particles are subjected to strict testing.
In the original factory test, the test equipment performs a complete test process according to the program, which can better ensure the compatibility of the particles (particle compatibility determines the compatibility of the memory) and durability (the durability of the particle determines the overclocking ability and service life).
Choose high-quality PCB circuit boards
The effect of a high-quality PCB board on memory particles is similar to the effect of a stable and reliable motherboard on the CPU.
You should try to choose more layers and thicker PCB circuit boards. In fact, in Intel's very early specifications, it is stipulated that memory modules must be manufactured with 6-layer PCB, and there are corresponding strict requirements for PCB material, layer spacing, copper thickness, circuit layout parameters and other processing technologies.
There should be as many chip resistors and capacitors as possible on the PCB, and as thick gold fingers as possible. When purchasing a motherboard, everyone will be very concerned about the number of chip resistors and capacitors and the welding process. Similarly, high-quality memory modules cannot be slack in the use of chip resistors and capacitors.
Choose the right capacity and frequency
The capacity of memory is not only a factor that affects the price of memory, but also a factor that affects system performance. In the past WindowsXP platform, the memory of 512M was still the mainstream, but now, without the memory of about 4GB, the smoothness of the operation may not be guaranteed.
However, the memory capacity is not necessarily the bigger the better. When purchasing memory, everyone should choose according to their own needs, so as to achieve greater value of the memory. For consumers who are still using 32-bit XP systems, 2GB of memory is a better choice, while 4G or higher memory and a 64-bit system can maximize the performance of the computer.
Like the CPU, the memory also has its own operating frequency. The higher the main frequency of the memory, to a certain extent, the faster the memory can achieve. However, high-frequency memory modules cannot be blindly selected, and should be purchased according to the relevant parameters of the personal computer, such as the larger frequency supported by the motherboard and the larger capacity supported by a single slot.
Anti-counterfeiting
At present, some memories often use different brands and models of memory particles, and you can see the difference at a glance. At the same time, the fraudulent means of grinding memory particles will be used, and then new numbering parameters will be printed.
Generally, the polished chips are dull and have a fluffy feeling, and the handwriting on the overprint is blurred and unclear. These are generally counterfeit memory products. In addition, it is also necessary to observe whether the PCB circuit board is clean, whether there are burrs, etc., and whether the gold finger has obvious traces left by plugging and unplugging. If there is, it is likely to be a reworked memory product.
After a brief introduction of the industrial computer, I believe that everyone has a certain understanding of the choice of memory, and I hope that it can help you when installing or upgrading the memory, and choose the memory that suits you.
