Installed Kingston HyperX Impact [HX424S14IBK2/32] 32Gb. Works great!

Thanks a lot, roberttrevellyan! Now I can buy 32 Gb RAM with confidence

I have a Mac (Retina 4K, 21.5-inch, 2017) 3.0 GHz Intel "Core i5" processor (7400). The Apple website says that with such a processor you can install only 16 Gb of RAM maximum, and for 3.4GHz quad-core Intel Core i5 (Turbo Boost up to 3.8GHz) you can install up to 32 Gb. In the comments they ask about how much you can install as much as possible and they are always answered - 32 Gb. Does this mean that the processor model is not important?
