Several Reddit posters and WCCF Tech claim criminals are targeting AMD Ryzen processor inventory with RMA fraud. Basically, fraudsters buy Ryzen 5 and 7 processors, resell the Ryzen chips and return the original package to Amazon (or its partners) with an old Intel processor.
Scammers remove the Intel markings from the integrated heatspreader and replace them with legit-looking Ryzen markings. The Intel CPUs used for these scams are close enough in weight, appearance, and size to fool basic checks conducted by non-tech savvy employees.
The scam itself is very elaborate. Apart from the fact that it is very clearly an LGA based Intel processor (the distinctive shape of the PCB is obvious to any PC enthusiast), the scammer(s) managed to remove the Intel markings on top of the package and even place legitimate-looking Ryzen markings. I have no doubt that this has the potential to fool a first time builder. That said, if the AM4 motherboard bought is the real deal then the chance of permanent damage is relatively low. Since AMD AM4 motherboards do not have any pins on the socket, there’s nothing much to mess up the motherboard unless you try to use overly excessive force, potentially break the socket seat itself.
WCCF Tech found two Reddit users that received a fake Ryzen CPU. Fortunately, Amazon handled the situation by offering a refund plus a gift card.
