How to judge the authenticity of Kingston's memory?

Naming rules of AMD OPN code:

The OPN code of AMD K8 CPU follows the following format.

xx x * * * * x x x * xx

1 2 3 4 5 6 7 8

take for example

ADA4400DAA6CD, SDA2500AIO3BX, ADAFX55DEI5AS, etc.

The following subfields explain the meaning of OPN.

1 segment, AD/SD/OS, respectively representing A64/Sempron/Opteron.

Section 2, power limitation, A/K/B= standard /55W/35W (Snapdragon),

A/O/D= standard /65W/35W (desktop series)

3 segments, model, i.e. product code, such as 4800, 3000, FX55, etc.

4 segments, encapsulation type, A/C/D/I respectively represent 754/940/939/AM2 interface.

5 segments, core voltage, A/E/I/K respectively.

1.35。 1.4V variable/1.50v/1.40v/1.35v.

6 segments, the highest surface temperature of CPU, and A/O/P/K represent variables /69/70/65 degrees respectively.

7 segments, L2 cache total capacity, 2/3/4/5/6 stands for128k/256k/512k/1m/2m.

8 paragraphs, core process, two English letters,

The first a starts with 130nm process, and b or c starts with 90nm process.

2. Identify the hard disk:

Maxtor's hard disk used to have a 7-digit serial number, but since Diamondmax Plus9, its hard disk serial number has changed to 13. However, what is useful for us to identify the hard disk is the first 7 digits. The number of Maituo is mostly "serial number+maximum capacity of this series of hard disks+first place+capacity+interface type+number of heads".

Our simple expression is "XX, XXX, X, X".

The two "X's" in the first part indicate the product family and model.

"3" is equal to or less than 40GB, and "9" is greater than 40GB. This series is the first generation of star diamonds.

"2R" means fireball 53 1DX, the first generation of American diamonds.

"2B" means fireball 54 1DX American diamond II.

"2F" means fireball 3.

"4W" refers to Diamondmax 536DX Star Diamond II.

"4D", "4K" and "4G" are all represented as Diamondmax 540X star diamond three generations.

"4R" means Diamondmax 16 star diamond four generations.

"5T" stands for the sixth generation of Diamondmax Plus60 gold diamond.

"6L" stands for the seventh generation of Diamondmax Plus D740X gold diamond.

"6E" means diamond plus 8.

"6Y" means diamond plus 9.

The three "X's" in the second part represent the capacity, and the unit is GB. For example, "080" or "200" are expressed as 80GB or 200GB respectively.

The "X" in the third part indicates the buffer capacity, interface and spindle motor type.

"D" refers to Utral ATA/33.

"u" means Utral ATA/66.

"H" stands for Ultra ATA 100 interface with 2MB cache.

"J" stands for Ultra ATA 133 interface, 2MB cache and ball motor.

"L" stands for Ultra ATA 133 interface, 2MB cache, and hydrodynamic bearing motor.

"P" stands for Ultra ATA 133 interface, 8MB cache, and liquid bearing motor.

"M" means serial ATA 150 interface, 8MB cache, using liquid bearing motor.

The "X" in the fourth part indicates the number of magnetic heads used, that is, the number of recording surfaces, so the storage capacity per disk can be calculated by the formula of "storage capacity per disk of hard disk = 2 × total capacity of hard disk/number of magnetic heads". However, starting with Diamondmax Plus9 of the diamond series, the number changed to "0", but we know that Diamondmax Plus9 of the diamond series is all based on storing 80GB of products per disc, so the changes here will not affect our recognition.

Let's take Diamondmax Plus9 hard disk with serial number "6Y200M006500A" as an example. We already know that the first seven digits of this number are useful to us, so we see that the capacity of this hard disk is 200GB, serial ATA 150 interface, 8MB cache and liquid bearing motor.

3. Identify cpu and memory

The instructions of the fake goods are folded like a piece of paper, and there is no serial number of the CPU; The manual of the real product with serial number is like a small book. The anti-counterfeiting label for returning to the moon has no stereoscopic effect.

The numbers in the manual and the numbers on the box CPU are also encoded on the fan. The genuine product has 1 1 leaves, and the aluminum cooling surface is marked with the following words.

CMK8-7 1520-A 14-GP

0703FDGP 14

Made in China

On the top cover of CPU, 65nm/90nm AM2 Athlon64 3600+ X2 has three lines of similar core definition numbers, namely "ADO 3600IAA 5DD", "CAALG 0706RPAW" and "Z284883B70 154". Wherein the first behavior core specification definition, the second behavior core period definition and the third behavior core serial number definition. Among them, A of ADO in the first row stands for Athlon processor, S stands for Athlon processor, followed by DD stands for 35W, DH stands for 45W, DO stands for 65W, DA stands for 89W, DX stands for 125W processor ("3600" below Athlon 64 stands for the PR value model of the processor; "IAA" stands for the socket type of CPU, for example, "A" stands for socket 754, "D" stands for socket 939, "I" stands for scooter AM2, and the following "AA" stands for the core voltage and maximum core temperature limit of the processor respectively; The following "5" indicates that each core of the processor has a level 2 cache of 5 12K; "DD" means that the processor uses the Brisbane core, which is also the key to distinguish between 65nm and 90nm products, because the Athlon64 3600+ X2 of the previous generation 90nm Windsor core is "CU".

How to identify the true and false laser agent Kingston memory stick-false target hotline 8008 1083 15 or 8007 1603 15, another false memory hotline 8008 1083 15. Therefore, if the received Kingston products use 8008 1083 15 or 8007 1603 15 as the hotline to identify fakes, they can be directly judged as fakes. Please pay special attention!

As the world's largest memory manufacturer, Kingston has considered possible fakes since the product was launched, and specially established an online inquiry system to identify the authenticity of Kingston's memory according to the unique ID number of each memory. Therefore, through this official anti-counterfeiting method to identify the correct Kingston memory, it must be genuine.
