Will the memory work properly?

Question

Iron

Hello.
Here is the situation:
I bought a PC, they shoved me a memory of 1600Mg, but my mother does not support 1600Mg and cuts it to 1333Mg. If I buy for 1333Mg, will they work without friezes and other things, the old one for 1600Mg and the new one I buy for 1333Mg?
Thank you!

Answer 1

They will be no problem, but will be truncated by the minimum frequency of the slowest bar (i.e. 1333).
