Something about the information from Digitec about this RAM is not right.
According to Digitec, it should be DDR4-2133, which is rather slow by now and explains the low price.
According to the manufacturer's no. BL2K16G30C15U4B, however, it should be DDR4-3000.

For an AMD Ryzen, for example, it should be at least DDR4-3200.
