Scammers are selling counterfeit DDR5 RAM with plastic chips

Counterfeit DDR5 RAM is circulating across online storefronts and gray-market retailers, and some fake modules are convincing enough to pass visual inspection — until you cut them open. According to Digital Trends, the chips installed on the fraudulent sticks aren't memory at all, but merely fiberglass boards shaped to resemble legitimate DRAM.

The issue was reported by a Japanese X user who purchased what appeared to be a genuine SK Hynix SO-DIMM laptop module and physically dissected it after becoming suspicious. Inside, they found non-functional fiberglass pieces where the memory chips should have been.

"At first glance, they look like regular memory sticks, but the chips actually installed on them are just bare circuit boards—plastic boards. I removed them and cut them open to check," reads a translation of the X post.

Some of these counterfeits are reportedly being sold openly on auction platforms like Yahoo Japan under listings marked "untested" or "junk," with sellers explicitly refusing returns.

The problem is compounded with desktop DDR5 kits, where large heatspreaders cover the memory chips entirely. Without visible chips to inspect, Digital Trends notes, buyers often have no way to confirm what they've purchased until a system fails to boot or crashes repeatedly.

The conditions for this kind of fraud are straightforward. DDR5 prices have been rising sharply for over a year, driven by AI-related demand that has sparked a global memory crisis. And as memory manufacturers prioritize enterprise and server production over consumer supply, there's no end in sight for shoppers.

Mashable previously reported that Framework, the modular PC maker, raised its DDR5 prices multiple times through late 2025, with a 48GB module jumping from $240 to $620 over the course of months. Samsung warned manufacturing partners of further price hikes to come, with major laptop makers including Lenovo, Dell, and HP warning of price increases.
