As memory prices continue to rise, the PC market is facing a new crisis: counterfeit DDR5 memory modules have begun to circulate in large quantities through multiple retail channels (including online e-commerce and offline physical stores). Some fakes even use plastic to pretend to be DRAM chips, and their appearance is enough to look fake.
A Japanese social platform user shared a typical case. He purchased a 16GB DDR5 SO-DIMM notebook memory labeled as manufactured by Samsung, only to find that it was completely fake:
·The gold finger (metal contact) has an abnormal appearance, with rounded edges instead of standard right angles.
·The memory chips actually come from SK Hynix, but the label says Samsung
·Some fakes have the power circuit in the wrong location or don’t match it at all.
For DIY players who are familiar with hardware, such fakes may not be difficult to identify. But for ordinary consumers, it is often difficult to distinguish authenticity. In particular, desktop memory modules are usually covered with heat dissipation vests, which cover the DRAM particles. It is almost impossible to detect fraud without disassembling the heat sink or testing on the computer.
What’s even more worrying is that these fake memories are being sold openly. On the Japanese Yahoo auction platform, the same fake 16GB DDR5 SO-DIMM module is priced at 12,845 yen (approximately RMB 573). The product description clearly states that this is a "junk item", its function has not been confirmed, and the seller does not accept returns.
Memory fraud is becoming a new disaster area after graphics cards and CPUs. In a market environment with high prices, consumers need to keep their eyes open to avoid paying high prices to buy back a piece of "plastic memory."
