Some netizens said that thanks to the domestic memory, if it is not Changxin, not the domestic memory, the price of the memory may also rise sharply. In the past, foreign particle factories, casually blackout, a fire, will lead to huge fluctuations in the price of memory modules. Now this kind of thing is basically gone. Take the recent pollution accident in the Japanese flash memory factories of Western Digital and Jiaoxia, which have affected the supply of flash memory with a capacity of 6.5 EXB, and have not caused large price fluctuations in the domestic SSD price, let alone a crazy rise.
What does this mean? It shows that domestic production does have a good inhibitory effect on hardware prices. If there is no domestic production, the price of the memory module will find a reason and rise in a rumbling way. For example, the current DDR5 memory module, because there is no domestic production, so its price has risen very crazy, all far more than the original price, and even with the graphics card price increase has a fight.
Now, there are more and more memory brands that support domestic Changxin granules, which shows that netizens' recognition of Changxin granules is also getting higher and higher. In fact, there are still many memory sticks that can be bought on the market now, using domestic Changxin granules. For example, Guangwei, Langke, Weigang and so on. Recently, Jinbaida also launched the first memory bar using Changxin granules, and the main product is still cost-effective. However, there is one more god operation, that is, the 3200MHz high-frequency memory is marked as a frequency of 2666MHz to sell. In this way, netizens have a feeling of picking up leaks, and I have to say that this feeling is still very good. I also found out when I got the product and did the test.
Jinbaida's 8GB DDR4 2666 desktop memory module adopts a single-sided particle design, with eight Changxin original particles on one side and blank on the other. In terms of frequency, Jinbaida is very conservative, and the label labels a relatively low 2666MHz frequency. To be honest, this frequency is basically only suitable for entry-level platforms. But in fact, it is a genuine 3200MHz high-frequency product, anyway, I let Jinbaida this wave of god operations are a little confused. Some brands are eager to mark the frequency of memory sticks higher and higher, but Jin Baida does the opposite, marking the high as low to sell.
At present, I have only seen two kinds of Changxin particles, one is that the particles are printed with the words "cxmt", this is the Original Changxin particles, with a certain overclocking ability, basically everyone can easily go to the frequency of 3600MHz. Even some special particles can reach 4266MHz, support XMP 2.0 automatic overclocking technology, the timing can be controlled at 18-22-22-42, and the voltage is standard 1.35V. The other kind of particle is the Changxin particles encapsulated by Guangwei's parent company Jiahe Jinwei, which is printed with the word "Yi". The overclocking ability of this particle is very general, and it is even impossible to overclock, and its frequency is generally 2666 or 3000MHz. The memory module using Changxin original granules and the third-party self-encapsulated Changxin granule memory modules, there is a difference of almost 20 to 30 yuan between the two. When you start, you still need to distinguish it, so as not to spend more money to buy non-original Changxin granules.

In fact, many netizens are struggling, in the end, is it one step in place, start with DDR5 memory, or save money to start DDR4 memory? In fact, this really does not need to be entangled. Because as long as you are entangled, it means that there must be poor money, and the poor money will of course enter DDR4. Don't look at the lack of domestic DDR5 memory now, its price will rise to the sky. However, its performance is not strong, and you will definitely be disappointed after starting. DDR5 really wants to become mainstream, at least two or three years away. The current DDR5 memory is not very good, just like the DDR4 memory module just came out, basically the frequency of 2133MHz started, and now, the frequency above 3000MHz is bought at will. The same is true for DDR5 memory, which is now too low at 4800MHz and too high in timing, so the performance gain is not noticeable. So the motherboard I started here is to support DDR4. In fact, I am looking forward to the future to be able to launch a motherboard that supports both DDR4 and DDR5 memory, remember when DDR4 was just listed, there were motherboards that supported both DDR3 and DDR4 memory.
MSI MAG B660M MORTAR WIFI DDR4 mortar, using 12ch 60A CPU intelligent power supply, ISL99360 DrMOS, titanium inductor. Level I9 non-K-series processors can be easily supported.

The Price Difference between the WiFi Version and the Regular Edition is around 50 to 100.
Weigang Frost Shield Dazzling 360 integrated water-cooled radiator this kind of inexpensive, full of water-cooled products are very suitable for ordinary users, even if you do not overclock, it will not be too wasteful. The main features of this water-cooled product are: infinite mirror LED magic light effect water cooling head design, PWM intelligent temperature control heat dissipation, Rifle bearing fan, 80.3CFM air volume and 2.69mmH20 wind pressure, support for 3Pin ARGB Daisy Chain series, support for 12th generation Core processors, and its own lighting effect remote control.
Weigang LEGEND 840 SSD PCIe4.0 1TB SSD is a very practical product, the performance is a high-end level, sequential write, read speed is basically around 5000MB/s, compared with flagship products, there are still some gaps. However, its 4K performance is outstanding, comparable to flagship products. Temperature control is also very good, in order to strengthen the heat dissipation, the product is also equipped with a thin and light heat sink as standard, which can be compatible with notebook computers.
In terms of main control and particles, INNOGRIT (Yingren Technology) IG5220BAA main control and self-sealing particles are adopted, and the particles have the ADATA standard on them. Supports the latest NVMe 1.4 protocol, SLC Caching and LDPC error correction mechanism. In terms of after-sales, it offers an original warranty of five years, or a write life of 650TBW.
The graphics card shows an older product, the Colorful iGame GeForce RTX 2060 SUPER Vulcan X, which belongs to the Rainbow Vulcan system and is a little cheaper than the Water God series. I have to say that now the domestic brand graphics card design is more and more personalized. Do you know that back then, Rainbow was only one of the five tigers of Tongde, right? Now it is basically in the graphics card industry, and it can also be regarded as the existence of the top five.
In terms of power supply, MSI's MPG A850GF rated 850W full module computer power supply, the price is very high, and MSI is built for 30 series graphics cards, so it will be more worry-free to use it to bring 30 series graphics cards. Everyone should pay attention to the fact that the instantaneous power of the 30 series graphics card is very good. If you do not do the relevant optimization, it is also prone to problems. This is also the 30 series graphics card just listed that will, there are some more than 1000W power supply, but also brought about the problem of movement, damage.
From the power supply nameplate information, it adopts four 12V outputs, supports 12V intelligent single-track joint output, 12V graphics card output is 480W, and 12V CPU output is 300W, which can fully meet the needs of high-end graphics cards and high-end CPUs.
It is the flagship product in the MSI power supply series, supporting a ten-year warranty, 80PLUS Gold certification, all-Japan capacitors, using a full module design, flat module line. Using a 14cm FDB bearing fan, the noise is only 22dB during operation.
Now the price of the monitor is also getting cheaper, to know that the previous liquid crystal display is not cheap. I have to say that in fact, the price reduction of liquid crystal displays, one is the continuous development of technology, and the other is that there is a domestic BOE. However, BOE is still slightly worse than Samsung in the high-end. However, the medium and low end is already remarkable. MSI MAG274QRF-QD 27-inch gaming display, using Rapid IPS fast LCD panel, original color quantum dot technology, support 2K (2560×1440) resolution, 165Hz refresh rate, 1ms GTG fast response, 147% sRGB ultra-wide color gamut, HDR Ready technology, NVIDIA G-Sync Compatible tear protection, shadow dynamic lift and other functions.
Display on the side of the display, support free lifting, support ninety degree rotation, various angles can be adjusted. It supports the adjustment of pitch (-5 degrees to 20 degrees), lifting (0 to 100mm), left and right (-75 degrees to 75 degrees) and rotation (-90 degrees to 90 degrees).
With RGB lights on the back of the monitor, MSI's Mystic Light glare system is supported, and users can adjust it according to their preferences. When measured at night, you can still see its light effect, and during the day, the light effect is very general. In fact, I still like to design a projection on the base, and put the light effect on the desktop, which feels better. The display has added RGB elements, mainly to enhance the esports atmosphere.
Next, it was a practical test of Jinbaida's 8GB DDR4 2666 desktop memory module.

Master Lu directly displays the name of Jinbaida's 8GB DDR4 2666 memory module, which is Jinbaida DDR4 3200MHz 8GB, and the production date is the product in December last year.
The memory module information measured by AIDA64 software can be seen that the manufacturer of DRAM is cxmt, that is, Changxin particles. Its XMP is 3200MHz.
The memory module information measured by typhoon software is A-die particles, 22 nanometer technology, and genuine Changxin particles. It is said that the market occupancy rate of Changxin granules is now about 5%, which is still very weak compared with the three giants of Samsung, Hynix and Micron.
Through the CPU-Z software, you can see the detailed memory module information, where JEDEC is the timing of 2666MHz, there are three types. As for the only one XMP, it is the XMP3200, the timing is 16-20-20-38, and the voltage is 1.35V. It is recommended that you directly open the XMP option in the motherboard BIOS, so that it is in a 3200MHz high-frequency state, so that it can play its performance more.
At the 3200MHz frequency, where Read is 49362MB/s, Write is 46671MB/s, Copy is 46782MB/s, and Latency is 68.4ns.
Of course, Changxin original granules also have a certain overclocking ability, through the toss found that after overclocking, there is a problem of Gear1 and Gear2. And the memory stick of This Jinbaida in my hand can only run in Gear2 mode, so it still has a certain impact on performance.
At 3600MHz, Read is 48271MB/s, Write is 48917MB/s, Copy is 47720MB/s, and Latency is 84.4ns, and the performance improvement is not ideal. It seems that it is better to treat it as 3200MHz memory. At present, the overclocking function of the B660 motherboard has not really been perfected, and there are still many BUGS.
The development momentum of Changxin granules is still very fierce, and the product categories are becoming more and more abundant, in addition to ordinary memory strips, there are different products such as vest strips, lamp strips, notebook strips and so on. There are also special Changxin granules for overclocking users to choose. Although Changxin is still a distance away from Samsung, Hynix, and Micron in the whole. But I believe that this distance will only get smaller and smaller. And this year, Changxin's DDR5 particles will also be mass-produced, and then DDR5 memory will usher in the real domestic memory. Jinbaida 8GB DDR4 2666 memory stick, the name of this product, is caused by some netizens to misunderstand. In fact, it is more accurate to change it to a Jinbaida 8GB DDR4 3200 memory module. As for the price, it is now 189, which is still somewhat competitive. Of course, it would be better if the price was a light bar, or a vest bar.
