Careful with what you buy, Fake DDR5 RAM is flooding the market, especially in Asia. Real DDR5 memory costs much more due to shortages and high demand. Scammers are making fake sticks that look like the real thing. These fakes copy big brands like Samsung and SK Hynix. Inside, they use plastic dummy chips instead of real working memory chips. Some also have wrong or fake power parts. A common example is 16GB DDR5 laptop RAM sold on Yahoo Japan. Sellers list them as “junk” or untested items with no returns allowed. The price is around $85. If you install them, your computer usually will not start at all, or it may crash and run badly. Here is how to spot them: >Real RAM has sharp, straight edges on the board. Fakes often have rounded edges. >The small power chips look strange or different. >The board feels thinner or looks a lighter color. On desktop RAM, the metal cover can hide the fake chips until you remove it. Always buy from trusted sellers only, I wouldnt risk my whole PC for saving some money
