In Q4 this year, DDR5 48GB (24x2) memory modules are very hot. Large capacity, high frequency, low **, who doesn't like it!However, there are many DDR5 48GB (24x2) products on the market, and it is inevitable that they will be uneven. The most important thing about memory modules is memory particles. Today, we will learn about the purchase and pit avoidance of DDR5 48GB (24x2) memory modules through memory particles.
DDR5 48G 24G is currently mainly Hynix MDe 3G8 particles and Micron BDie 3G8 particles. Let's start by understanding how to identify memory granular information. First, the memory SPD is read by the Thaiphoon Burner software to view the particle code, but this method is not necessarily accurateSecond, if you are very sure of what kind of particle the memory is, and you are very confident in the product, and do not worry about the warranty (disassembly is not guaranteed), you can disassemble it, and then look at the memory particle encoding. Micron memory particles, we need to query the particle code from the ** of the particle identification, understand the naming rules, and interpret the particle information. Hynix memory particles, we know its particle code, understand its naming rules can directly get the details of the particles.
1. Micron BDIE 3G8: Original standard, big S
1. Original standard particles
Micron DDR5 memory chips, generally there is no particle code on the grain. You need to go to the official website to find it according to **. As shown in the figure, the second line d8dcn.
Upon searching, we see that its particle code is MT60B3G8RW-56B:B.
This is the information of Micron's original standard DDR5 24GB memory particles, we see that there are currently three main MT60B6G4, MT60B3G8, MT60B1536M16, which are BDIE products, with a speed of -48B (4800MHz), -56B (5600MHz), -64B (6400MHz). Therefore, it is known that MT60B3G8RW-56B:B, this is the original DDR5 memory particle BDie product of Micron, with a speed of 5600MHz.
2. Spectek (large S) particles
The DDR5 memory particles of the big S do not have a particle code on the same grain. And according to the first line ** on the particles, it is not easy to find on the official website of Micron. We searched directly for 24GB to find the file in question.
We can see that there are currently 2 types of DDR5 24GB memory particles for big S, PRN3G8Y4CAB8RW-XX, PRM3G8Y4CAB8RW-XX, also known as BDIE chips, with a speed of -48B (4800MHz), -56B (5600MHz), and -64B (6400MHz).
We can judge whether the particles are the original standard or large S white flakes by the particle surface label. Or look at the particle code, the one that starts with MT is the original Micron standard, and the particle code PRN starts with the big S white film. The particle code "-" is followed by the velocity frequency. It's good for everyone to understand this. Because anyway, it is not recommended to choose the DDR5 24X2 of Micron particles.
2. New Hynix MDIE 3G8: quality grade, speed grade
1. Quality grade
At present, the mainstream DDR5 24 48G memory modules on the market are all new Hynix MDie 3G8 particles, with original standard particles and white chip particles. The original standard particles of the original factory are the particles that have passed the quality test and are self-sealed and marked by the manufacturer. White chip particles are particles that are of inferior quality, but can be used normally, and are shipped under other labels, or the wafer is shipped from other factories. The quality of the original standard particles is better than that of white film granules.
The products using the original standard particles of the new Hynix MDIE are: Guangwei Shence DDR5 24*2, Zhi Fantasy Blade DDR5 24*2, Corsair DDR5 24*2, Asgard Blowing Snow DDR5 24*2, Xinlux Crazy Blade DDR5 24*2, etc. Among them, Guangwei Shence DDR5 24*2 is the most cost-effective, and the time of release is the time when DDR5 24*2 is reduced. In the past, the 1999+ DDR5 24*2 could be called the nobility of the memory module, but now 1299 can be played.
The product using the new Hynix MDiE white film granules, Guangwei Longwu DDR5 24*2 This is undoubted;In addition, there are some products that are specially selected, selected, and carefully selected on the detail page. But don't pay attention to this. Everyone remembers that the DDR5 24*2 memory module of the new Hynix MDIE on the market within 900 yuan is all made of white chip particles. At present, the DDR5 24*2** of white film new Hynix MDix particles is less than 800, which can be purchased. This**is similar to Micron's**, so fools choose Micron particles' DDR5 24*2.
Not to mention 800 900, even if Micron particles' DDR5 24*2 is more than 700, I believe many players will not choose. You see, I didn't sell a few sets on Pinxi. This shows that although there are many big deceptions, there are not many kinds of big injustices.
2. Speed grade
Let's first talk about the rules of the new Hynix MDIE particle encoding. As shown in the figure above, the first 3 bits of the particle code H5C are fixed;The first digit is GD GJ, or GY, which stands for capacity 24G 48G;The 6th bit 8 represents the structure 8 particles;The 7th bit m represents mdie;The first digit indicates the frequency speed class.
Remember that the last 2 digits of the letter M indicate the speed level, EB level 4800MHz, GB level 5600MHz, HB level 6400MHz. The higher the base frequency of the memory, the higher the speed level of the granularity, and the higher the limit that the memory module can reach. EB grade, limit about 7000MHz;The current limit for GB and HB grades is 8800MHz. The GB level of the white film can also easily be 8000MHz.
At present, the flagship-level DDR5 24*2 memory module uses the original standard of the new Hynix MDIE GB-grade particles, or even better HB-grade particlesThe middle end uses the original standard MG grade particles, and the white flake GB particlesThe low-end ones use EB particles with white flakes. The pit is coming, those who say that Hynix selects special selection of carefully selected particles DDR5 24*2 memory module with a base frequency of only 4800MHz, please stay away, be careful to fool you lame.
Finally, let's summarize.
1 Pit avoidance: Micron BDIE (original standard. Large S white flakes) particles of DDR5 24*2 memory modules;Hynix MD5 24*2 memory module with MDIE EB grade white chip particles;On the evening of the spell, those granules are unknown, and they sell 8 900 miscellaneous DDR5 24*2 with their heads and faces covered. None of these are recommended.
2 Purchase: DDR5 24*2 memory module The correct purchase is to give preference to the original standard of the new Hynix MDIE particle productsSecondly, no matter how poor it is, you must choose the GB grade granules of white film New Hynix MDIE. After all, players who have a demand for DDR5 24*2 memory modules, who don't want to have both large capacity and high performance, there is no need to spend 7 800+ and wronged themselves.
Under the impact of domestic high-end memory, now DDR5 24*2 memory modules are already very affordable. It's just that more than 2,000 ** babies who bought a certain odd and a boat DDR5 24*2 memory stick, I heard that it was a big loss to sell salted fish.
