This is the way to do it (I'll be using a random part):
- Go to PCPartpicker, and to select RAM
- Find the RAM you like, and select it.
- Scroll to "Part #" and copy the code
- Go to the list, press Crtl+F, paste the part number, and if there are any matches, then your RAM should be compatible, if not, keep looking.
Following the method I described, the sticks you selected should be compatible. Part number is CMK8GX4M2B3000C15. The thing about that one, is that it shows up twice. Here is why that could be a problem:
It says that version 3.21 is supported, but not 4 DIMMs. However, I am not sure what that version number is supposed to mean. Maybe you should find something else. Like this one:

That one shows up on the list, and the 4 DIMMs seem to be working when populated, so I think we found your RAM. And it's 3200MHz so even better. Build is a bit over budget but not by much.
