Little secret about memory particles： I didn’t expect the difference between different particles to be so great.
[PConline Miscellaneous Talk] Speaking of memory, there may be nothing to talk about for ordinary people. Although it is an indispensable hardware in computers, as long as the capacity is large enough, the impact on games and daily use experience is not strong. But for DIY players, it is what they have been pursuing. Although 3600MHz may be a few frames higher than 2400MHz, the number looks very comfortable.
There are three main factors that determine memory overclocking. One is IMC (Memory Controller) with CPU, which is mainly related to IMC design, and it is the same as CPU constitution. IMC of each processor of the same model will have physical differences. Followed by the motherboard and motherboard BIOS, it depends on the adjustment of motherboard manufacturers; Finally, it depends on the memory particles. Today, Xiao Bian will take you to know the mainstream memory particles, and it is also convenient for everyone to buy cheap and easy-to-use memory that can be overclocked.
What is the difference between memory particles?
Why are there physical differences between memory particles? First of all, there are many manufacturers who produce memory granules, which should be known to many DIY players. Here is a brief list. At present, 90% of memory granules in the consumer market are produced by three giants from the United States and South Taiwan Province, such as Magnum, Hynix and Samsung. In addition, South Asia, Winbond and Lijing will also produce them. However, these latter manufacturers mainly produce server memory granules now, and the consumer market is relatively small.
Domestic purple DDR3 memory particles
Memory particles are DRAM chips. Each manufacturer has different technological research and development capabilities, different chip designs and different manufacturing processes, so the quality of the chips produced will naturally be different.
Even the memory particles produced by the same manufacturer will develop iteratively. For example, Hynix’s first-generation DDR4 memory particles mainly include particles ending in MFR, such as H5AN8G8NMFR and H5AN4G8NMFR, which are called MFR particles by the people. These particles can run stably at the frequency of 2666MHz or 2400MHz, but there is almost no overclocking potential, and crazy voltage application cannot succeed. Subsequently, Hynix introduced particles ending in AFR. This generation of particles significantly improved the overclocking performance, and the frequency was significantly increased when pressurized. Now it has been iteratively developed to the third generation of CJR particles.
What are the mainstream memory particles at present?
So what are the mainstream memory particles at present? Let’s talk about manufacturers.
Hynix
For example, Hynix is used. Let’s talk about Hynix granules first. Just now, I also said that the DDR4 memory particles promoted by Hynix’s first generation areMFR particle(also known as Hynix M-die), 25nm process, MFR particles are stable and durable, but almost no overclocking ability, and now it is more common in low-frequency DDR4 memory.
However, compared with Samsung’s excellent overclocking physique in particles, Hynix is at a disadvantage. In order to improve this situation, Hynix has launched three kinds of particles, namely, H5AN8G6NAFR(8Gb), H5AN8G8NAFR(8Gb), H5AN4G8NAFR(4Gb) and H5AN4G6NAFR(4Gb), at the end of 2015, and announced that.AFR particles(also known as Hynix A-die). Generally, the AFR particles with 21nm process have better overclocking ability than MFR, and it is not difficult to apply voltage at 3200MHz, but their physique is not good, and the timing at high frequency is also very general.
In order to compare Samsung’s advantages in high-frequency memory, Hynix has devoted itself to research and development for several years, and finally launched CJR particles that have been on fire for nearly two years.
HynixCJR granulesIt is SK Hynix C-die particle, which is the third generation of 8Gbit particles after MFR and AFR. It adopts the process of 1X nm (usually 18nm), and it is also called CJR particle because of the suffix of model "H5AN8G4NCJR". CJR particles have good physical fitness, and more importantly, they are very compatible with the Ruilong platform which has been on fire in recent years. It is easy to go up to 3600MHz, so it has become the darling of DIY players, especially AMD platform players.
In addition, Hynix has also introduced a new generation.JJR(J-die) granulesHowever, this particle is to replace the previous MFR and AFR particles, and the overclocking constitution is slightly worse than that of CJR particles.
To sum up briefly, among the mainstream Hynix particles in the market at present,According to physical fitness, CJR>JJR>AFR>MFR.Of course, it is not excluded that there are some special cases with good physical fitness that can be committed below.
Orion’s belt
As early as DDR3 era, Samsung memory particles were very superior, and established a reputation in DIY circle, and so was DDR4 era. Here, we have to mention Samsung B-die.
Samsung B-die is the legend of overclocking in DDR4 era, most of which are 20nm processes, and countless memory overclocking records are completed by him, which is the best grain in DIY players’ hearts. Samsung B-die has good compatibility with AMD and Intel, and it is the basic operation to reach the frequency above 4000MHz on Intel platform, and the timing sequence is still very low, which is very popular among players.
But the B-die particles we often talk about are actuallyEspecially BCBP particles in 5WB suffix series such as K4A8G045WB and K4A8G085WB.These particles are specially selected for flagship memory, soMore precisely, a person with good health should be called a special B-die..
Although the rest of the ordinary B-Dies have good physique, they don’t have the strength to challenge overclocking records. There is also a kind of B-Dies with scraps. These are the worst B-Dies.
Ying Chi HOF OC Lab uses Samsung B-die.
However, it is a pity that Samsung announced the discontinuation of B-die granules last year, and the legend of the first generation ended. Now it is increasingly difficult to buy Samsung B-die granules’ memory in the market, and some memory manufacturers used it to manufacture flagship products, which is expensive.
Samsung A-die and M-die have replaced B-die particles. The new particles have improved the density, and the single particle capacity is larger, which reduces the cost and facilitates the manufacture of a single 32GB or larger memory. According to Samsung, A-die has the same or even better super capacity as B-die, and the capacity is larger, while M-die is inferior. However, such a good granular Samsung is mainly used in the professional market and server market, and the consumer market has not yet reached it. It may not be accessible to our ordinary consumers until the production capacity goes up.
In addition, there are C-die and E-die Samsung particles on the market at present, and these constitutions are relatively average.
To sum up, let’s discuss the Samsung memory granule constitution that everyone can buy at present.Specially selected B-die > ordinary B-die > scrap B-die>C-die≈E-die.However, A-die and M-die will not talk about it because they have not been bought in the market and have not been measured.
magnesium light
Previously, the presence of magnesium particles in DIY circle was still relatively low, generally stable and durable, but the overclocking performance was not as eye-catching as Samsung.
Magnesium B-die is an early DDR4 particle, and it is also a particle with a large shipment of magnesium. This kind of particle is stable and durable, but don’t think about how to overclock it, just buy it by default.
In addition, Spectek, a subsidiary of Magnesium Light, specializes in handling degraded particles that are unqualified in magnesium light testing. These degraded memory particles will be marked with Spectek’s big S logo, which is called big S particles. Large S particles are degraded films of magnesium light, but there are also good and bad ones. For example, magnesium light produces memory particles with a frequency of 3,200 MHz, and the ones that fail to meet the requirements are downgraded to the 2400MHz standard for processing and sales. Then you can’t say that these particles are garbage particles that fail to meet the requirements of 3,200 MHz; However, some large S particles are screened by low-end memory screening standards, and the yield is extremely low. These are garbage particles.
Large s particle mark
Therefore, the big S particles are mixed, and they are also the memory particles that many cottage memory chips like to use. It is better for DIY players who are not specialized in reading the particle models to avoid them.
Of course, with the passage of time, as well as Hynix, Magnesium has E-die great efforts to launch a batch of particles that are easy to get high frequency and the key price is not expensive. It is the recent fire, which broke the DDR4 memory overclocking record with a score of 5726MHz.
Magnesium E-die is a particle produced by magnesium at the end of 17 years, but few people played it before Samsung B-die stopped production, and it was not until 19 years that it was discovered by versatile DIY players. In the hands of overclocking players, it is not difficult to overclock magnesium E-die to 4000MHz, but the voltage should be increased relatively high, and the time sequence is difficult to narrow. Although there are some flaws, Magnesium E-die has been popular recently, because at present, Magnesium E-die is mainly used in the original memory of Yingruida, and the lowest price is only over 200, which is very affordable and can be called a civilian Ferrari.
Different types of magnesium E-die particles also have physical differences. At present, C9BJZ is the best one in folk practice, followed by D9VPP, while others are not obviously different from ordinary B-die.
If you give an order to the particle constitution of magnesium light, it is probablyE-die C9BJZ>E-die D9VPP > other e-dies > b-dies > big s.
After reading each summary, everyone should be able to understand which particles are better, but how should they be sorted if they are summarized? Don’t panic, here xiaobian simply summarizes a simple memory particle ladder table for your reference, and friends who need it can also save it.
So what about memory particles?
Under normal circumstances, the surface of memory particles has its number, but now the memory basically has a vest, so it is unrealistic for ordinary consumers to take apart the vest to see the particles.
At this time, a more convenient way is through the software Thaiphoon Burner, which can read all kinds of information in the memory. Let’s teach you how to use it.
After Baidu downloads the software, open it directly and click Read in the red box to enter the information page.
This is the memory produced by Shiquan, which uses Hynix Hynix granules. The granule number ends with CJR, and the model number also indicates C-die. Obviously, this memory is made of Hynix CJR granules.
By analogy, this memory is the D9VPP E-die of magnesium light.
This memory is Samsung’s B-die for BCPB.
However, the typhoon is not completely accurate. It is estimated based on its big data, but it is also close. If you want to see it, it will be more reliable to remember to update the software to the latest version.
summary
In fact, except for a small number of DIY enthusiasts, the physique of memory particles has no effect on most people. Most people buy memory and go back, and it is very comfortable to use XMP by default. This article is also for DIY enthusiasts with a very small audience.
For this part of the enthusiasts, Xiao Bian finally gave a suggestion to buy. Samsung’s B-die has been discontinued, and now it basically only exists in the flagship memory with high price, so it is unnecessary to force it too much. At present, the C9BJZ is mostly used in magnesium’s own Yingruida memory, and the self-operated Yingruida ballistix 3000MHz vest strip on a Dongping platform is mostly made of C9BJZ particles. At present, this memory is also sold out of stock at a higher price, so players who like tossing can pay attention to it.
