One of the key points in the daily maintenance of the memory stick is to wipe the memory stick. So how to wipe the gold finger of the memory stick? This problem may give some computer users a headache. I will introduce it in detail below. Let’s take a look at how to clean the oxidation of the gold fingers of memory sticks.
How to clean memory slots and gold finger oxidation of memory strips
Memory slots:
1. First clean the memory with an oil paint brush Dust in the tank.
2. Use a leather tiger to blow away the dust in the tank.
3. Use a paintbrush to apply washing water (trichlorethylene) to clean the memory slot.
4. While the washing water is still wet, scratch the corners of the old memory stick and wipe the memory slot.
5. Clean with washing water or 95 alcohol. After the above 5 steps, the success rate is 90%.
Memory module:
1. Use an oil paint brush to clean the dust on the surface of the memory.
2. With the gold finger facing down, take a paper towel and dip it in a little gasoline to wipe the gold finger. (PS: Do not let gasoline get on the memory circuit board and particles when wiping. After wiping, it needs to be dried in the shade to avoid sunlight.)
3. You can also use a hard eraser to wipe and reinstall the memory afterwards.
Supplement: Common memory maintenance tips
1. For memory golden fingers and graphics card oxide layer failures caused by dust, we should use rubber or cotton dipped in alcohol to clean them, so that they will not The screen will be black.
2. Regarding the problem of mixed memory insertion, 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 better. On the contrary, it may cause Lots of questions. Principle of mixed memory insertion: Insert low-standard, low-standard memory into the first memory slot (that is, DIMM1).
3. When only one memory needs to be installed, the memory socket close to the CPU socket should be preferred. The advantage of this is that it can be cleaned when the memory is contaminated by dust brought out by the CPU fan, and the socket It is extremely difficult to clean after being contaminated.
4. Install the memory module. There is a latch on both sides of the DIMM slot. When the memory gap is correctly aligned and plugged in, the two teeth should automatically lock the memory. . There is only one notch on the gold finger of DDR memory. The two sides of the notch are asymmetrical and correspond to a ridge on the DIMM memory slot, so the direction is easy to determine. For the previous SDR, there were two gaps, and it was easy to determine the direction. However, SDR has gradually faded out of the market, so it doesn’t hurt to learn about it. When pulling out the memory, you only need to move the two latches outward. , the memory will automatically come out of the DIMM (or RIMM) slot.

Check the memory labels: The genuine Kingston memory labels are printed clearly and regularly, while the fake ones are obviously rough and light, and the fonts appear relatively thin. In addition, the formatting rules of real and fake Kingston memory labels are also very different, so 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, in sharp contrast to the genuine ones. For a memory, the PCB circuit board only accounts for about 10% of the cost of the memory, while the memory particles are the focus of determining the price of the memory. Therefore, usually the PCBs of fake products are basically manufactured by regular OEMs, while the particles are made of "white flakes" in the jargon, which is what we call defective products. They are cheap but have poor stability and compatibility.
Check the registered trademark logo: the genuine Kingston’s registered trademark? R
Another point, carefully observe the watermark inside the label. There are obvious traces at the connection between the fake memory watermark and the KINGSTON font, proving that it is post-printed, which will not appear in genuine Kingston memory.
Gold finger identification: The following is the gold finger of a genuine Kingston memory. The gold fingers of genuine Kingston memory are pure in color, and the gold finger connections in the purple square are gold-plated; the gold fingers of counterfeit Kingston memory are slightly dull, and the gold finger connections in the red square are copper sheets of the PCB board and are not Gold plated.
Identification of the fonts on the PCB board: The left is genuine Kingston memory. Genuine Kingston memory has uniform fonts with no obvious size difference, and has relevant certification symbols. The counterfeit Kingston memory has different fonts and no relevant certification symbols.
K-label: This is a macro shot using a SLR camera, and the flash is turned on to capture the authentic and fake labels. The laser pattern of the authentic label can see dense silver powder particles. The K-character is not obvious, and the background appears. blue. The letter "K" on the counterfeit label is very obvious, and the density of the silver powder particles is low.
Flip the angle to view anti-counterfeiting: The laser anti-counterfeiting label of genuine Kingston memory can show two patterns by changing the angle. The first pattern has a silver powder effect on the upper half and a half K stain on the lower half. ; The second pattern has a silver powder effect on the lower edge and a half-K shape on the upper edge. The counterfeit label has only one pattern, which is a very obvious K word.
