as I understand it, now you can take any of

or are there pitfalls?

Answer 1

On the websites of the main memory manufacturers there is a configurator, type in the name of the motherboard or chipset and it displays the appropriate models
www.kingston.com/ru/memory/search/devices?DevicesT... The
website of the motherboard manufacturer has a list of compatible modules

Yes

Answer 2

If you decide to take one or two, then two are better, they will work in two-channel mode, and usually cheaper. An exception is if you plan to increase more memory soon, and there will be no more free slots.
