How to replace RAM?

Question

Iron

Good day, dear ones. Such a problem: one of the RAM sticks failed (it costs two 4 gigabytes each):
Type DDR3
Size 4096 MBytes
Manufacturer Kingston
Max Bandwidth PC3-12800 (800 MHz)
Now it seems like you need to change it, but how? Buy another one? But they seem to be the same, but I'm not sure I'll find one.
Or crush a toad (it’s a pity to throw out the working bar) and immediately take a pair to replace it?

First you need to google "The structure of the system unit for the smallest." And secondly, learn to read.
