In the first paragraph:

Group A numbers indicate the name of the chipset, which is directly represented by the chipset, such as INTEL's P55, AMD's 770, etc.

Group B numbers indicate that the motherboard supports memory:

None- indicates that only DDR 3； is supported;

T- means only DDR 2； is supported; (This is the opposite of gigabytes)

C stands for COMBO, which supports both DDR2 and DDR 3；;

Group c numbers indicate the motherboard size:

None-indicates that the sample plate type is ATX；; ;

M—— indicates that the plate type is MicroATX；;

I- indicates that the orifice type is MiniITX；;

In the second paragraph:

Group d numbers indicate product family positioning:

X-extreme (supreme level) User objects: overclocked users and top players;

(Note: It has multiple graphics card slots and the most comprehensive additional technology, providing powerful computing power for top overclocking users and high-performance users such as graphics workstations);

G-gaming (player level). User target: mainstream game users;

(Note: the mainstream configuration design has strong expansibility and good overclocking ability);

Electronic entertainment (entertainment level). User objects: home users and multimedia users;

(Note: Integrated chipsets are mostly used, but they are decoded by high-definition hardware and have rich interfaces);

P- major (professional level). User object: business users;

(Note: low power consumption, low cost, contributing to data security and protection, and also having certain scalability);

C-classic (standard entry level). User object: beginner user;

(Note: the low-cost design caters to the needs of novices, but there is a separate graphics card slot, which is more cost-effective);

The number of group E is relatively simple: if there is a D, it means that MSI has its own "Dr. MOS" technology.

"Drmos" technology is similar to ASUS's "Xtreme Design", which combines some unique technologies of MSI. Dynamic energy-saving technology of packaging "green power"; "XpressCool" technology, using heat pipe to dissipate heat and reduce noise; And "RapidBoost" technology to strengthen power supply and improve overclocking ability.

The number of group F is represented by numbers, which represents the positioning level of products. The higher the number, the higher the level.

9-equivalent to the diamonds in the old number (diamonds, flagship series);

7 ~ 8- equivalent to the platinum in the old number (platinum, the second top series);

4 ~ 6- equivalent to Neo (mainstream series, positioning the middle end) in the old number;

1 ~ 3- equivalent to the value in the old number (input value sequence);

Group G number indicates the functional level of the motherboard:

0- extreme value function;

5- fully functional;

3- alto function;

1- basic functions;

For example:

Let's talk about the 785GTM-E45 motherboard in the picture, which uses a 785G chipset. Group b is numbered t, which means that only DDR2 memory is supported; The number m in group c represents the small plate of MicroATX; Group d number e indicates that the motherboard is family multimedia entertainment type; Without e group number, there is no DrMOS technology; The number 6 in group F indicates that it is located in the middle of the mainstream; Group G number 5 indicates the complete function type.

H55M-ED55, using H55 chipset; There is no group B number, which means that only DDR3 memory is supported; The number m in group c represents the small plate of MicroATX; Group d number e indicates that the motherboard is family multimedia entertainment type; Group e, number d, means having DrMOS technology; The number 5 in group F indicates that it is located in the middle of the mainstream; Group G number 5 indicates the complete function type.

Take 780GM-ED65(v 2.x) as an example:

780g-stands for chipset model, such as 790GX, 780g, 790F, etc. The 780G here obviously uses the AMD 780G chipset.

M- represents the size of the motherboard, that is, the size of the PCB substrate. For example, we often say ATX version, mATX version and so on. Among them, ATX (big board) will not appear in the product name, and MicroATX is replaced by the letter M, such as 780 GM-ED65；; MiniITX will be replaced by the letter I; DTX will be replaced by the letter d.

E- represents the application category of this motherboard. For example, eXtreme stands for extreme series, and the letter X is used instead of products. For high-end users, it is an all-round top motherboard; Gaming stands for game series, with the letter G instead of products, aimed at gamers; Entertainment stands for entertainment series, and the product is changed to the letter e, which focuses on high-definition and digital device connection; Professional stands for professional level, and the letter P is used instead of the product, which is stable and overclocked and can be purchased by game users. Classic stands for classic practical series, and the letter C is used instead of products, which stands for high cost performance and strong practicability, and is suitable for entry-level users to buy.

D stands for DrMOS. It is a brand-new intelligent energy-saving technology of MSI, and the version with the letter D will provide more efficient power utilization.

6—— This letter represents the classification of the motherboard. We often hear the names of MSI Platinum Edition and Diamond Edition. In fact, we don't know English. We can recognize it by looking at the letters. The number 9 represents the high-end diamond version; Numbers 7-8 represent platinum edition; Numbers 4-6 represent gold or neo versions; The number 1-3 represents the entry-level version.

5- No practical significance. It can be understood as motherboard level and added value. Need to compare with the previous serial number, the bigger the serial number, the better. The number 0 represents ATX or mATX version.

V2. x- represents the current motherboard version. Motherboard will be constantly modified during its life cycle, including BIOS, etc. V stands for version, 2.x stands for the current revision number, and the updated version stands for improving the compatibility of processors and other aspects. Usually, the motherboard has made long-term expectations when it leaves the factory and has passed the test. Not all models of motherboards will have new revisions.
