Hello, I have a set of 2x8GB Viper DDR4 (PV416G300C6K) in front of me for my next system. This kit was purchased new from Amazon a few days ago, however close inspection reveals marks on the contacts of each module showing that they have been previously inserted into a socket. Do these completed modules go through some kind of factory testing which could account for these marks, or did I perhaps get a used kit from an unscrupulous Amazon supplier?

The package also didn't contain a case badge with the Patriot logo like I saw in many of the reviews for this kit. Aside from the modules themselves there is only a decal of the stylized Viper logo. I assume this is normal and just the result of minor packaging changes.
