Ask HN: What to do with counterfeit hardware?
I fear it is likely to be some kind of counterfeit item - maybe someone is just counterfeiting label and boxes to defraud unsuspecting buyers, who may not have other sticks to compare.
I tried calling amazon, they said to just return it. I asked my call to be escalated, they didn't seem to care much. Returning it for a refund won't help solve the problem: there are counterfeit items that somehow end up on legitimate resellers site.
I would never have caught that if I had not run a memtest and checked the SPD information.
So I ask HN: what should I do? Who cares about counterfeit hardware, except the client? (there is some serious price difference between DDR3L 2133 and 1600)
