When it comes to domestic memory sticks, there will always be some netizens who are dismissive. It's not that the technology is too backward, or it's that the price is too high, there is no cost performance, or it can't be overclocked. Anyway, they can definitely find a lot of reasons to confirm that domestic memory modules are not as good as foreign memory modules. But the reality is that it directly hits their face, because the domestic memory strip is getting better and better, and the price is getting cheaper and cheaper. You know, before the advent of domestic memory particles, foreign particle factories have a period of time, there will always be a thousand strange accidents, not blackouts, try to fire, and then the price of memory sticks will be like sitting on a rocket, rubbing up.
Remember a few years ago, an 8G capacity DDR4 memory stick, surprisingly less than half a year, from more than 200 to more than 800, this dare you believe? But this is the truth, but since the domestic Changxin memory particles listed, I have not seen the price of memory sticks rise sharply, but the price of memory sticks is very stable, and it is stable and small. With this alone, I feel that domestic memory modules have won.
Recently, the price of domestic memory strips has opened a price reduction mode, and there have been many good prices. For example, the so-called 8G 2666MHz memory module of Jinbaida is very cost-effective. It is itself an XMP-3200 MHz memory module, which can basically go up to 3600MHz. Is not overclocking, directly open XMP, when the 3200MHz memory module to use is also very fragrant.
I started two, did not expect to be serial, it is said that the serial number is easier to overclock, in fact, this is just a psychological effect, the advantage of the serial memory bar is that the particles are basically the same batch, generally will not appear due to different particles, and the compatibility problems caused, relatively stable. As for whether it can be overclocked and the serial number has little to do with it, it mainly depends on the quality of the particles. This 8GB DDR4 2666 desktop memory module of Jinbaida adopts a single-sided particle design, with 8 1G Changxin original particles on one side and a blank PCB board on the other side.
You can see that the memory particles are printed with the words "cxmt", indicating that it is Changxin original particles. In addition to the Original Changxin particles, there are also some memory modules that use third-party self-encapsulated Changxin particles. For example, the Changxin particles of Guangwei's parent company Jiahe Jinwei's own package are printed with the words "Yi" on the particles, rather than the words "cxmt". In general, original granules are better than third-party self-encapsulating granules. In addition, there are specially tuned Changxin particles, which can only be seen in high-end memory. I also have it in my hand, but it's an RGB vest strip, and I can't see the real situation of the particles at all.

For users who do not like toss and want to save money, it is most appropriate to use 12 generations of non-K series processors with B660 motherboards. For motherboards, it is recommended to prefer a version that supports DDR4 memory modules. Because according to the actual performance of the current DDR5 memory module, at least three or five years, the DDR4 memory module is still mainstream. In addition, domestic DDR5 memory particles, if everything goes well, then this year will achieve mass production, then DDR5 memory modules will definitely reduce prices.
The motherboard used for testing is MSI's MAG B660M MORTAR WIFI DDR4 mortar, which is very generous in terms of workmanship and materials, using 12-way 60A CPU intelligent power supply, ISL99360 DrMOS, titanium inductor, and dual 8Pin interface power supply, which can easily support I9 level non-K series processors.
This motherboard is designed with two PCIe Gen4 x4 channels of 2280 M.2 interface, which can perfectly support the NVMe protocol PCIe 4.0 x4 SSD. The one close to the CPU is directly connected to the CPU and does not support SSDs of the SATA protocol. The second is an SSD that is directly connected to the south bridge chip and supports the SATA protocol. Both interfaces are equipped with SSD expansion heat sinks (Frost Armor). The motherboard sound card is ALC1200, under the 24pin power supply interface, there is a front USB 3.2 Gen2 Type-C (10Gbps) and a USB 3.2 Gen1 Type-A (5Gbps) expansion port, next to an ASM1543 chip, used to achieve the Type-C port front and back blind plug, but both interfaces need chassis support to use normally.
This motherboard interface is very rich, the motherboard in I / O interface, from left to right is four traditional USB2.0 interface, a DP interface, an HDMI interface, three USB 3.2 Gen 2 10Gbps Type-A interface, a USB3.2 Gen2x2 20Gbps Type-C interface, as well as 2.5G wired Lan port, WiFi antenna socket interface and audio interface.
For non-K series 12th generation Core products, the built-in heat sink is generally unable to hold down, because as long as the CPU occupancy rate is high, its heat generation will become very large. Therefore, the use of third-party air-cooled radiators, or water-cooled radiators, is a better choice. Weigang Frost Shield Colorful 360 integrated water-cooled radiator is very cost-effective, using wireless mirror LED magic light effect water cooling head design, support PWM intelligent temperature control heat dissipation, the use of Rifle Bearing fan, you can get 80.3CFM air volume and 2.69mmH20 wind pressure, in addition, this water-cooled product also supports 3Pin ARGB Daisy Chain series.
As for the graphics card, it is not much to introduce, I have a lot of bright card in my hand, but this rainbow iGame GeForce RTX 2060 SUPER Vulcan X graphics card is the only graphics card I can get my hands on at present. For game users, if you use a 1080P monitor, it is enough. But if you use a 2K 144Hz display, or even a 4K display, then it is a bit of a struggle, and the performance is not as good as the 3060 graphics card.
Jinbaida KP230 1000GB SSD, using M.2 interface (NVMe protocol), belongs to the KP230 series. However, it is also the vest version of the YLR P2 SSD series, essentially they are the same product, including the master control, particles, these are exactly the same, but also support the Computer Storage Executive's toolbox software. The only difference is that the brands are different and the after-sales time is different. The KP230 1000GB SSD is backed by a 600TBW, or three-year warranty. The Yredia P2 1000G SSD comes with a 300TBW, or five-year warranty.
Jinbaida K230 1000G SSD adopts the group PS5013-E13-31 master control, is a 4 flash channel, PCIE 3.0 x4 design, compatible with TLC and QLC flash memory, maximum capacity 2TB, no cache design, with SLC dynamic cache acceleration technology.
In terms of NAND flash memory particles, micron's original IMB22 NX893, 256GB 96 layer stacked 3D QLC NAND particles, consisting of 4 1TB, of which 24GB is used as a backup wear supplement block, and the actual usable capacity is about 931GB (1024 decimal). As for the 1000G in the product name, it is 1000GB (1000 base). Its read speed is about 2400MB/s, the write speed is about 1900MB/s, although the performance is not very strong, but it is not weak, and the heat dissipation is good, running at full load for a long time, and the temperature has not exceeded 55 degrees.
In terms of power supply, it is still MSI MPG A850GF full module computer power supply, its rated power is 850W, which is enough for now. Even after the 40 series graphics card is listed, there is no need to change the power supply, but the 40 series graphics card supports PCI-E 5.0, so the graphics card power supply interface will also be upgraded to PCI-SIG 12VHPWR H+ (including 12pin power terminals, and the side of the 4pin signal terminal) interface. But don't worry, this power supply can fully use 3 8-pin to PCIe Gen5 power cords.
From the power nameplate information, it adopts four 12V outputs, supports 12V intelligent monorail joint output, 12V CPU output is 300W, and 12V graphics card output is 480W, which can fully meet the needs of high-end graphics cards and high-end CPUs.
This power supply has three 8-pin graphics card interfaces, just can be upgraded to 3 8-pin to PCIe Gen5 power cords, this conversion cable is believed to be on fire after a while, but the premise must be your old power supply to support.
The display used for testing was MSI MAG274QRF-QD, a 27-inch gaming display that uses a Rapid IPS fast LCD panel, true color quantum dot technology, support for 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 resistance, shadow dynamic boost and other features. In fact, so many parameters, you just need to remember that it is IPS, 2K, 165Hz can be.
The back of the display has its own RGB light, which supports MSI's Mystic Light glare system, and the base supports ninety degree rotation, which can be adjusted at various angles and can be freely lifted and lowered. Among them, it supports the adjustment of pitch (-5 degrees to 20 degrees), left and right (-75 degrees to 75 degrees), rotation (-90 degrees to 90 degrees) and lifting (0 to 100 mm).
The hardware information display measured by Master Lu.
Jinbaida 8GB DDR4 2666 memory module, Master Lu directly gave a frequency of 3200MHz, which is much higher than 2666MHz.
Cpu-Z measured the memory module information, you can see that it has four modes, three are JEDEC and one is XMP. Here I will briefly introduce that JEDEC is the memory specification standard, and XMP is the SPD extended memory preset file specification.
At present, the only memory specification standard-setting body in the world that has been recognized by the IT industry and the memory industry is JEDEC. The full English name of this JEDEC is the Joint Electron Device Engineering Council, the full name of the Chinese is the Joint Committee on Electronic Device Engineering, and the normative standard for memory is formulated by the Solid State Technology Association under JEDEC.
XMP can't actually be called a memory standard, because it is an INTEL-defined SPD Extended Memory Preset File Specification. XMP is to add a file called Profile to the SPD chip of the memory module, which records a series of parameters and voltages when the memory is set to a certain frequency. Because these parameters can not comply with the JEDEC specifications, can be the manufacturer's own parameters, so a lot of low-frequency memory, as long as through XMP can become high-frequency memory. It is precisely because XMP can make it easy for memory manufacturers to make high-frequency memory, so it is deeply loved by major memory manufacturers.
The JEDEC standard should take care of everyone, for compatibility, stability, so it is not open to high frequency at the beginning, it is absolutely in line with industry standards and can operate absolutely stably and produce. XMP is only a modification made by memory manufacturers for their own memory, not necessarily stable, so some netizens will open XMP, the computer will appear blue screen, unstable problems.
Simply put, in a word, JEDEC is the native frequency, very stable, XMP is copied, not necessarily stable. So Jinbaida 8GB DDR4 2666 memory module, its native frequency is 2666MHz, XMP frequency is 3200MHz.
Viewed through the Typhoon software, it can be seen that it uses memory particles that are A-die, using 22-nanometer technology.
The manufacturer of DRAM measured by AIDA64 software is cxmt, which is Changxin.
Directly turn on the XMP function, using AIDA64 software for testing, Jinbaida this memory module at 3200MHz frequency, Read is 49362MB/s, Write is 46671MB/s, Copy is 46782MB/s, Latency is 68.4ns. During the test, it was found that The 8GB DDR4 2666 memory module of Jinbaida was very stable at a frequency of 3200MHz. So, I'm going to overclock it at a higher frequency.
Through many tests, I found that with my ability and the platform in my hand, I can exceed the 8GB DDR4 2666 memory module of Jinbaida to 3600MHz.
The 12th generation Core platform has the problem of Gear1 and Gear2, so we should pay attention to it, do not pursue the high frequency of memory too much, so as not to have the problem of stable operation in Gear2 mode, and also depends on whether the timing is high or low, not too high.
Through the AIDA64 software test, Jinbaida's memory module is 48271MB/s, Write is 48917MB/s, Copy is 47720MB/s, and Latency is 84.4ns at 3600MHz. In general, the performance of memory has risen and fallen, but the increase and decline are not obvious, so it is most appropriate to use it at a frequency of 3200MHz.
I have to say that jinbaida this memory stick with the price of 144, coupled with domestic long-core original granules, is still very powerful. Although it has no vest and no RGB lamp, it has a frequency of 3200MHz, which can be achieved by directly turning on XMP, which is very practical for the B660 platform.
