Memory is one of the most important components of a computer. The performance of memory directly affects the normal work of the computer, and one of the important parameters of memory performance is the frequency of memory chips. So, what does Win7 think of the frequency of memory chips? Below, let's take a look at the method of Win7 to check the frequency of memory chips.

method steps

method 1. view the related commands of the command line memory bar

1. press? Win+R? Key to open the operation, input in the operation? cmd? ; Or click the command prompt

2 in the start menu bar, enter after entering the command prompt? wmic memorychip? ; This is the command to view the relevant parameters of the memory stick.

3. Then you can see the frequency of the memory chip.

Method 2. View through the software application. Here we introduce 36 security guards

1. Open the security guards and select? More? ;

2. after you go in, find it inside? Master Lu? , click? Add? ; Master Lu is also an excellent software for computer hardware performance testing and process monitoring

3. Hardware detection? , you can see the details of the memory stick.

Supplement: Common maintenance skills of memory

1. For the failures of memory gold fingers and oxide layers of graphics cards caused by dust, everyone should use rubber or cotton to clean them with alcohol, so that the screen will not be black.

2. With regard to memory mixing, when upgrading memory, try to choose the same memory as your existing one. Don't think that buying new mainstream memory will make your computer perform a lot, on the contrary, there may be many problems. The principle of mixed memory insertion: insert low-standard and low-standard memory into the first memory slot (DIMM1).

3. When only one memory needs to be installed, the memory socket close to the CPU socket should be preferred. This has the advantage that the memory can be cleaned after being polluted by dust brought out by the CPU fan, but the socket is extremely difficult to clean after being polluted.

4. Install the memory stick. There are two claws on both sides of the DIMM slot. When the memory gap is aligned correctly and inserted in place, these two claws should automatically connect the memory? Bite? Live. There is only one gap on the gold finger of DDR memory, and the two sides of the gap are asymmetric, which corresponds to a rib on the DIMM memory slot, so the direction is easy to determine. For the previous SDR, there are two gaps, and it is easy to determine the direction, but SDR has gradually faded out of the market, so it is no harm to know; When pulling up the memory, just move the two claws outward, and the memory will automatically come out of the DIMM (or RIMM) slot.

Check memory labels: genuine Kingston memory labels are printed clearly and regularly, while fakes are obviously rough and light, and the fonts are relatively thin. In addition, the typesetting rules of the true and false Kingston memory labels are also very different, please observe carefully.

Check the memory particles: It can be clearly seen from the Kingston memory particles in the picture that the genuine Kingston memory particles are clearly printed, while the fake memory particles are very dim, which is in sharp contrast with the genuine ones. For a memory, PCB circuit board only accounts for about 1% of the memory cost, and memory particles are the key to determine the memory price. Therefore, usually fake PCBs are basically made by regular foundries, while the particles are made of jargon? White film? , which is what we call inferior products, is low in price, but poor in stability and compatibility.

check the registered trademark logo: the registered trademark of authentic Kingston? R? A circle composed of the English letters "KINGSTON" is clearly printed around it, while the fake is just a round box that is obviously copied at random. One more thing, after careful observation of the watermark inside the label, there are obvious traces at the junction between the fake memory watermark and KINGSTON font, which proves that it is post-printed, which will not appear in the genuine Kingston memory.

gold finger identification: the following is the gold finger of genuine Kingston memory. The gold finger in the authentic Kingston memory is pure in color, and the gold finger connection part in the purple box is plated with gold; The gold finger of the fake Kingston memory is slightly dim in color, and the joint of the gold finger in the red box is a copper piece of PCB board, which is not plated with gold.

font recognition on PCB: the left is genuine Kingston memory. Authentic Kingston memory has uniform fonts, no obvious size difference, and relevant certification symbols. Fake Kingston memory has different fonts and no relevant authentication symbols.

K-shaped label: This is a macro shot with a SLR camera, and at the same time, the flash is turned on to shoot the true and false label. The laser pattern of the genuine label can see dense silver powder particles, and the K-shaped label is not obvious, and the background is blue. However, the K character of counterfeit label is very obvious, and the density of silver powder particles is low.

flip the angle to check the anti-counterfeiting: the laser anti-counterfeiting label with genuine Kingston memory can present two patterns by changing the angle. The first pattern is silver powder effect on the upper half edge and half k stain on the lower half edge; The second pattern has a silver powder effect on the lower half edge and a half-K shape on the upper half edge. The counterfeit label has only one pattern, that is, the whole presents an obvious K word.

query serial number: verification method: short message for memory product editing? M+ product SN serial number? Send it to 21233345

According to Kingston's official statement, I input? M36785241571636? Send it? 212333345? You can query the authenticity of the memory!
